Power Supply

A 230 watt power supply that is switch-selectable for 115 (100 - 120) or 230 (200 - 240) VAC powers the X-series deskside/LX system. The table lists the output ratings for the power supply.

The table lists 150 watts available for +5 volts and 96 watts for +12 volts. You will have to adjust your loads so that the combined total wattage for your system configuration is less than 230 watts.

For information about calculating the power consumption for your system configuration, see your product guide.

The combined continuous current drainCurrentDrain.5 for -12 volts and -5 volts should not exceed 1 ampere. For example, if the current for -5 volts is 0.0 amperes, the maximum current rating for -12 volts goes to 1.0 ampere.


Voltage	Maximum Continuous	Minimum Load	Peak Surge	Watts
+5	30.0 A	3.0 A	30.0 A	150.0 W
-5	0.5 A	0.0 A	0.5 A	2.5 W
+12	8.0 A	0.25 A	11.0 A	96.0 W
-12	1.0 A	0.0 A	Maximum capacitive load <350 mF	12.0 W

Current Drain

As an overall current drain limitation on the power supply, do not exceed the maximum output capacity of 30 amperes at +5 volts. The EISA slots on the system baseboard are rated at a maximum of 4.5 A per slot. The EISA specification recommends supporting an average of 2.0 A per slot. The average current consumption should not exceed 3.0 A per slot. The cooling efficiency varies per slot; therefore, ensure that adequate cooling is available in the target slot, especially in an expansion slot drawing more than 2.0 A.

Introduction

You can configure your X-series deskside/LX system by using one of the following methods:

· the system BIOS Setup Utility, which is stored in both the flash memory and the batterybacked memory of the real-time clock (RTC)

· the EISA Configuration Utility (ECU) on the System Configuration Disk which was shipped with the system

If your system does not have a diskette drive or it is disabled, use Setup to configure your system. Otherwise, use the ECU to configure it. The information you enter using the ECU overrides any entered using Setup.

If your diskette drive is disabled or improperly configured, you must use Setup to enable it so that you can use the ECU. If necessary, you can disable the drive after you exit the ECU.

Turning on Your System

Use the following procedure to turn on your system:

1. Make sure all external devices, such as a video display monitor, keyboard, and mouse, have been connected.

2. Remove drive protection cards (if present) from the diskette drive(s) and tape drive (if installed).

3. Before you connect the AC power cord to the system, make sure that the line voltage selector switch on the back panel is set to the correct line source voltage (see your product guide).

4. Make sure that the power cord is connected to the AC power input socket on the back of the system.

5. Make sure that the male connector of the power cord is plugged into a grounded AC electrical outlet. Refer to your product guide.

6. Turn on the video display monitor.

7. Turn on your system by pressing the power on/off push-button switch on the front panel (see your product guide).

8. Verify that the power indicator light on the front panel is lit (see your product guide).

9. After a few seconds your system begins a power-on self test. (POST).

Power-on Self-Test

Each time you turn on the X-series system, the power-on self-test (POST) runs automatically and checks the system baseboard, CPU module, memory, keyboard, and most installed peripheral devices.

During the memory test, POST displays the amount of memory that it was able to access and test. Depending on the amount of memory installed, it may take several minutes to complete the memory test. If you do not want to wait for the memory test to complete, you can terminate it after it starts by pressing [Spacebar]. After a soft boot ([Ctrl] + [Alt] + [Del]), POST does not test the memory. Depending on your system configuration, you may or may not see the following message on your video display monitor:

Press Spacebar to Abort Memory Test

Whether or not the above message appears on your video display monitor, the [Spacebar] remains active.

When POST reaches countdown number 135, the system beeps twice and, depending on your system configuration, may or may not display a message similar to the following:

To continue press:...................Spacebar
To configure system press:.................F1

If you do not press the spacebar or [F1], the above message remains for a few seconds, the system beeps once, and then the boot process continues. The [Spacebar] and [F1] remain active whether or not the above message appears on your monitor.

If the system halts before POST completes running, it will emit a beep code indicating a fatal system error that requires immediate attention. For a listing of beep codes and error messages that POST can generate, refer to "Error and Informational Messages."

Running Setup

The Setup utility, located in flash memory on the system baseboard, enables you to check or change the baseboard configuration information. It does not allow you to enter or change information about EISA add-in boards. Setup stores most of the configuration values in the battery-backed memory of the real-time clock (RTC); the rest of the values are stored in the flash EPROM. The values take effect when you boot up the system. POST. checks the values against the actual hardware configuration; if they do not agree, it generates an error message. You must then run Setup to specify the correct configuration.

You can run the Setup utility with or without an operating system being present.

Setup displays four pages of configuration fields: Setup Page 1, Setup Page 2, Setup Page 3, and Setup Page 4. To move from one Setup page to another, press [Pg Up] or [Pg Dn]. To select a field, use [Up] or [Down] to move the cursor to the field; the cursor moves only to the fields that you can change. Use [+] or [-] to change the value of the selected field. Each time you press [+] or [-], Setup displays one of the possible values of the field.

To save the configuration information and reboot the system so that the changes take effect, press [Esc] and then [F4].

Since values entered using the Setup utility are overwritten when you run the EISA Configuration Utility (ECU), you should only run Setup under the following conditions:

· To enable your diskette drive

· If you do not have access to a diskette drive

· If you have installed only ISA expansion boards in your system

Hard Drive 1

The Hard Drive 1 field lets you specify the drive type for hard disk drive C.

CAUTION: You must specify the correct hard disk drive type, because the system BIOS cannot independently verify this information. The system BIOS will not recognize the installed hard disk drive if the drive type is incorrect.

Note: We do not recommend mounting a hard disk drive in a 5.25-inch external peripheral bay because the drive may generate EMI. In addition, its susceptibility to ESD increases in the external bay.

Contact your sales representative or dealer for a list of approved add-in peripheral devices.

Select "Not Installed" if a SCSI hard disk drive is installed or if no hard disk drive is installed. If only one drive is installed, it will always be Hard Drive 1. In this case, select "Not Installed" for Hard Drive.

For information about the drive type, refer to the manufacturer's documentation packaged with the drive. Some manufacturers provide the drive parameters rather than the drive type.

If you know the drive type, use [up] or [down] to highlight the Hard Drive 1 field, and then press [+] or [-] until your drive type appears on the screen. For each drive type, the drive parameters also appear on the screen. The options include:

· Not Installed

· Type 1

through

· Type 47

If you have only the drive parameters, try to match them by stepping through the drive types and checking the displayed parameters for each type. If there is no match, select one of the user-definable drive types (2 and 3 or 48 and 49) to specify your drive's parameters. See "User Definable Drives."

Hard Drive 2

The Hard Drive 2 field lets you specify the drive type for hard disk drive D. The options are the same as those listed for hard drive.

Onboard SCSI

Depending on the model, the X-series deskside/LX system baseboard contains an onboard Adaptec AIC-7770, 32-bit dual channel SCSI controller. Enable H/W Only if the system does not boot up from a SCSI device connected to the embedded onboard SCSI controller, such as when you have only SCSI tape drives or CDROM drives installed; in this case, the SCSI drivers must be installed after running Setup. Enable H/W & BIOS if the system boots up from a SCSI device. Disable the Onboard SCSI field if you do not have SCSI devices connected to the system. Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

· Disabled

· H/W Only

· H/W & BIOS

SCSI, when enabled, uses hardware interrupt 11 by default. When SCSI is disabled, interrupt 11 is available. Use the ECU to edit the interrupts.

The Onboard SCSI field refers only to the SCSI controller, not the installed SCSI devices. To fully enable the Onboard SCSI field, you must run the ECU. See "Running the EISA Configuration Utility."

Note: If the onboard SCSI BIOS is enabled, it must not conflict with another system BIOS; for example, if the video BIOS is at E0000H, then the SCSI BIOS must be at a different address.

Run EZ-SCSI to install SCSI devices in your system when you are using DOS as your operating system. For information about running EZ-SCSI, see your X-Series SCSI Software User's Guide for the AIC-7770.

SCSI BIOS Mapping

If the onboard SCSI BIOS is enabled, it must not conflict with the onboard video BIOS; for example, if the onboard video BIOS3B8A0M4 is at E0000H, then the SCSI BIOS must be at a different address. Enabling the onboard SCSI BIOS in Setup assigns it to interrupt 11. Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

· C0000H

· C8000H

· E0000H

· EC000H

User Definable Drives

The User Definable Drives field allows you to enable the user-definable drive types 2 and 3 or 48 and 49. Select 48 and 49 unless there is a conflict with your network; if there is, select 2 and 3. Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

CPU Speed

The CPU Speed field lets you change the operating speed of the CPU. With the field set to Fast, the CPU runs at its full rated speed. With it set to Slow, the internal cache and any secondary cache are disabled and the system effectively runs like an 8 MHz IBM PC AT system. If a software application does not run correctly with CPU Speed set to Fast, try setting it to Slow. Some older applications and copy-protection software may require the Slow setting. Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

· Fast

· Slow

You can change the CPU speed during run time. For more information about changing the speed, see "Hot Keys."

Cache

Use the Cache field to enable or disable cache (both the internal cache of the CPU and the external cache module, if installed). Certain CPU modules support cache in the write-back mode. Enabling cache in the writeback mode causes it to perform faster. Enabling cache as write back on a CPU module that supports only write through causes the module to enable its cache in the writethrough mode. Disabling cache results in system performance degradation. You may want to disable the cache when you are using timing-loopdependent software. Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

· Disabled

· Write through

· Write back

I/O Recovery Time

Selecting Enhanced from the I/O Recovery Time field causes a fast I/O recovery time. If you experience problems (especially memory parity errors or poor video add-in board performance), then try Standard; the I/O recovery time is slower. The hardware guarantees system bus clocks (BCLKs) between I/O cycles as shown below:


I/O Recovery	8 Bit	16 Bit
Standard	11 BCLKs	3 BCLKs
Enhanced	6 BCLKs	2 BCLKs

The duration of one BCLK cycle is 120 ns at 8.33 MHz. Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

· Enhanced

· Standard

Posted I/O Writes

Selecting Enabled from the Posted I/O Writes field causes posted I/O writes to be executed which gives higher system performance. Setting the Posted I/O Writes field to enabled causes all memory write cycles and I/O write cycles to certain I/O addresses to be posted. The CPU module executes a successive cycle on the system bus while the write cycle is completing on the EISA/ISA bus. A successive cycle to the EISA/ISA bus gets delayed until the posted cycle completes. Setting the Posted I/O Writes field to disabled disables posting of memory write cycles and I/O write cycles. Write cycles to the following I/O address ranges are never posted: 0000H-00FFH, 0400H-04FFH, 0800H-08FFH, and 0C00H-0CFFH.

Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

· Standard

· Fast

· Disabled

Concurrent Refresh

Selecting Enabled from the Concurrent Refresh field causes concurrent refresh cycles to be performed. The CPU then executes out of cache or onboard memory while the EISA bus is being refreshed concurrently giving higher system performance. The maximum refresh cycle duration during a concurrent refresh is 125 ns. If EISA and onboard memory are coupled (a nonconcurrent refresh), then the refresh cycle duration is 1.2 ms. The CPU cannot execute until the EISA bus refresh cycle completes.

Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

· Enabled

· Disabled

Onboard Video BIOS Mapping

The Onboard Video BIOS Mapping field allows you to locate the video BIOS at E000:0000H - E000:7FFFH or C000:0000H - C000:7FFFH. Some applications require locating the video BIOS in segment C000 for compatibility. Selecting "To E0000H" maps C000:0000H - C000:7FFFH to the EISA/ISA bus. Selecting "To C0000H" maps E000:0000H - E000:7FFFH to the EISA/ISA bus. Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

· To E0000H

· To C0000H

If the onboard SCSI BIOS. is enabled, it must not conflict with the onboard video BIOS; for example, if the video BIOS is at E0000H, then the SCSI BIOS must be at C0000H. Enabling the onboard SCSI BIOS in Setup assigns it to interrupt 11.

Shadow C0000 to C7FFF

The Shadow C0000 to C7FFF field lets you enable or disable shadowing of area C000:0000H to C000:7FFFH. Shadowing memory increases performance by copying slow ROM into fast RAM. However, some BIOS code does not function correctly when it is shadowed. Use [up] or [down] to highlight the field, and then press [+] or [-] to change it. The options include:

· Disabled

Exiting Setup

After changing the Setup configuration information, press [Esc] to display the "Exiting Setup" menu. To save your changes and reboot the system, press [F4]. If you want to load the default options for all pages, press [F5]. If you want to exit Setup without saving your changes, press [F6].

Running the EISA Configuration Utility

If you install EISA add-in boards or add extended memory to the system, you must run the EISA Configuration Utility (ECU). This utility is on the System Configuration Disk. shipped with your system.

To operate properly, the X-series deskside/LX system needs information about the configuration of any EISA add-in boards that you have installed. The information is then stored in the nonvolatile flash memory. Use the ECU to specify and store configuration information about EISA add-in boards.

When you exit the ECU, it will update Setup configuration information stored in the battery-backed memory of the Real-time Clock (RTC), and the EISA configuration information stored in flash memory.

Note: The flash memory jumper E0190 must be in the default position, "normal boot," before you can run the ECU. Refer to "Flash Memory Jumper E0190."

Each EISA add-in board comes with a diskette that contains a configuration (CFG) file which describes the board's characteristics and the system resources that it requires. The X-series deskside/LX system board also comes with a CFG file. The ECU uses the CFG files and the information that you enter to specify a system configuration. It configures the system by writing the configuration information to flash memory.

You can also use the ECU to create system configuration information (SCI) files to use in configuring other systems. When you configure your system, the ECU automatically creates an SCI file that you can use to restore your system configuration; for example, adding or removing an EISA add-in board.

Procedure

The basic steps in running the EISA Configuration Utility are listed below:

1. Install the EISA add-in boards into your system. For information about installing add-in boards, see your product guide.

2. Turn on the video display monitor.

3. Turn on your system by pressing the power on/off push-button switch on the front panel (see your product guide).

4. Verify that the power indicator light on the front panel is lit (see your product guide).

5. Use Setup to enable the onboard floppy drive controller, to specify the correct type of diskette drive, and to enable or disable console redirection to the COM ports.

If you are using console redirection, enable console redirection, edit the CONFIG.SYS file on the System Configuration Disk, and add the /M and /B parameters to the "shell=" line; see "Command Line Parameters" for details.

6. Start the ECU by inserting the System Configuration Disk into the diskette drive and rebooting the system. When the ECU appears on your screen, press [Enter] to continue.

7. From the Main Menu, press [up] or [down] to highlight an item and then press [Enter] to select it. If you are using a mouse, point to an item and double-click the left button to select it. When you highlight an item, information about it appears in a popup window.

8. From the Main Menu, select "Learn about configuring your computer" for information about setting up your computer.

9. From the Main Menu, select "Configure computer" to load the configuration files.

10. From the "Steps in configuring your computer" menu, select "Step 3. View or edit details" and follow the steps on the screen. Press [F1] at any time for help.

You can also start the EISA Configuration Utility from drive A by typing ECU at the MSDOS prompt and pressing <Enter>. (To speed up the execution of the ECU, copy the System Configuration Disk to a directory on your hard drive and run the it from there.)

Command Line Parameters

Use the following command line parameters to run the ECU in different modes:

/A Advanced/Dealer mode. Displays advanced menu selections. You can also enter this mode by pressing [Ctrl] + [A] when the "Welcome" screen is displayed on your monitor.

/B BIOS video output. Uses the BIOS video support (interrupt 10H) routines for all video output. Use this parameter on systems with nonstandard video display monitors and when you have redirected the console to one of the onboard serial ports.

/F Automatic configuration mode. Configures the system by auto-adding EISA add-in boards and using valid flash memory for the configuration information. If the flash memory is invalid, the SYSTEM.SCI file will be used to obtain the configuration information.

/H High resolution display. Sets the display mode to 43 lines for an EGA add-in video controller board or 50 lines for a VGA board. The default is 25 lines for all add-in video controller boards.

/K Keyboard only. Prevents the system from supporting a mouse, even when one is present. The default is to support a mouse if a mouse driver is detected.

/M Monochrome display. Shows monitor screens using monochrome attributes, even on a color monitor. The default is to display color, unless a monochrome monitor is detected. Use this parameter when you have redirected the console to one of the onboard serial ports.

/N Modeling mode. Lets you open an existing SCI file or create a new one. If you use this parameter, the configuration is saved to a named SCI file rather than to the flash memory.

/P Permanent command interpreter. Indicates that there is no COMMAND.COM and the ECU is to reboot the system instead of exiting to the operating system. The ECU prompts you to press a key to continue with the reboot.

Hard Disk Group

The hard disk group is listed in "Step 3. View or edit details" in the ECU. You can install four 3.5-inch SCSI hard disk drives in the internal bays near the fan and two IDE or SCSI 3.5-inch hard disk drives in the internal bays near the power supply.

Note: We do not recommend mounting a hard disk drive in a 5.25-inch external peripheral bay because the drive may generate EMI. In addition, its susceptibility to ESD increases in the external bay.

Contact your sales representative or dealer for a list of approved add-in peripheral devices.

Hard Drive 1

The Hard Drive 1 field lets you specify the drive type for hard disk drive C. The options include:

· Hard Disk Auto-Configuration

· Hard Drive 1 Disabled

· Drive Types 1 - 47

· Drive Type 2 or 48 (User-definable)

· Drive Type 3 or 49 (User-definable)

Hard disk drive 1 must be configured to determine drive-specific parameters. If the hard disk drive controller can auto-configure the drive through the ECU, then you should select "Hard Disk Auto-Configuration." SCSI hard disk drives are usually selected as "Hard Drive 1 Disabled." Otherwise, choose the drive type for the drive from types 1 47. If hard drive 1 is not installed, then select "Hard Drive 1 Disabled."

Selecting either "Drive Type 2 or 48" or "Drive Type 3 or 49" requires you to enter specific parameters (cylinders, heads, precompensation, landing zone, and sectors). Some operating systems do not read BIOS drive type parameters above type 47; types 2 and 3 are provided for those operating systems.

Hard Drive 2

The Hard Drive 2 field lets you specify the drive type for hard disk drive D. The options are the same as those listed for hard drive 1.

Other Configuration Utilities

One of the selections from the main menu of the EISA Configuration Utility, "Access System Utilities," lets you set various system passwords and other configuration options. Some of these options are also accessible through Setup.

Cache

Power-on Password

Selecting "Set Initial Power-on Password" lets you enter a password that you will be prompted for when the system is turned on or rebooted. To enter a password, follow the instructions on the screen. You must enter the password a second time for verification. The power-on password also becomes the keyboard password when the system is turned on or rebooted (see "Network Password").

To change or remove the password, refer to the password part of the Setup utility.

To disable the password facility, set the password jumper to "Off" on the system baseboard. Refer to "Password Jumper E0390."

Network Password

Selecting "Activate Network Password" lets the system boot up, install all specified drivers, and wait for the password to be entered before it will allow access via the keyboard or mouse. The network password is the same as the power-on password that must be installed before the network password can be activated. This scheme enables the system to boot from a network server while retaining password protection for security.

Keyboard Password

Selecting "Set Keyboard Password" lets you enter a password for the keyboard. To enter a password, follow the instructions on the screen. You must enter the password a second time for verification. If one already exists, the utility asks if you want to change it. If yes, the utility prompts you for the old password, the new password, and then the new password again for verification.

After you have installed a keyboard password, you can lock the keyboard by selecting "Lock Keyboard." To unlock the keyboard, type the keyboard password and press [Enter].

To remove the keyboard password, reboot the system. If a power-on password exists, that becomes the keyboard password after the system reboots. There will be no keyboard password if you remove the power-on password and then reboot the system.

System Speed

Selecting "System Speed SLOW" slows the effective system speed to that of an 8 MHz IBM PC AT system for compatibility with certain older software. (In slow mode, all the primary and the secondary cache logic is disabled.) Selecting "System Speed FAST" enables the system to run at the full rated speed of the CPU. When you reboot the system, the system speed will revert to what you specified with the ECU or Setup utility.

Speaker

Selecting either "Speaker ON" or "Speaker OFF" lets you turn the system speaker on or off. When you reboot the system, the state of the speaker will revert to what you specified with the ECU or Setup.

Cache

Selecting either "Cache ON" or "Cache OFF" lets you turn on or off the system's caching capabilities (both the internal cache of the CPU and the external cache, if installed). When you reboot the system, the system caching will revert to what you specified with the ECU or Setup.

Hot Keys

The keyboard controller provides the following hot key sequences. Enter the numbers and symbols enclosed in [ ] by depressing keys on the numeric pad.


[Ctrl] + [Alt] + [Del]	Pressing these keys clears system memory and reloads the operating system. This is a "soft boot" reset.
[Ctrl] + [Alt] + [1]	Depending on your operating system or application software, pressing these keys (1 only on the numeric keypad) sets the system in the slow mode; it emulates an 8 MHz CPU.
[Ctrl] + [Alt] + [2]	Depending on your operating system or application software, pressing these keys (2 only on the numeric keypad) sets the system in the fast mode; it runs at its normal speed of operation.
[Ctrl] + [Alt] + [+]	Depending on your operating system or application software, pressing these keys increases the click sound made when a key is pressed.
[Ctrl] + [Alt] + [-]	Depending on your operating system or application software, pressing these keys decreases the click sound made when a key is pressed.

Installing Video Drivers

After you have configured your X-series deskside/LX system, you may install various video drivers to take full advantage of its onboard super VGA video controller. The system may not operate properly without the video drivers installed. In addition to the MSDOS and Microsoft Windows video drivers supplied with the system, you can obtain UNIX and OS/2 video drivers from your system supplier.

For the most current information on what drivers you need to install for your system's configuration, read the text file README.TXT that is in the root directory of each diskette in the base software kit supplied with the system. To install the drivers from the diskettes, follow the installation instructions in README.TXT.

The diskettes containing the video drivers provide procedures that take full advantage of the onboard Western Digital WD90C31 super VGA controller's enhanced features. To install these video drivers, do the following:

1. Fully configure your system. (This may include video DRAM buffer memory, application software, or new EISA/ISA add-in boards.)

2. Insert disk 1 of the video drivers and utilities for MS-DOS and Windows into drive A.

3. At the DOS command prompt, type A:install and press [Enter].

4. Follow the directions on the screen to install the video drivers.

If you are installing a third-party software package, you need to select the Paradise VGA video driver from the package. It will work on your system.

The super VGA controller on the system baseboard is a Western Digital WD90C31.

Beep Codes and Error Messages

If POST can display a message on the video display screen, it causes the speaker to beep twice as the message appears. However, POST cannot display messages when an error occurs before the video display is initialized. Instead, it emits a series of beeps.

For example, a failure of bit 3 in the first 64 KB of RAM is indicated by a 2-1-4 beep code (a burst of two beeps, a single beep, and a burst of four beeps). In addition, POST writes a value of 13H to I/O port 80H to enable debugging tools to identify the area of failure.

The related topics below list the beep codes and the values that POST writes to I/O port 80H when it encounters error conditions. They list fatal errors (errors that halt the system), nonfatal errors (errors that are not serious enough to halt the system), and other conditions that have no beep codes.

Before You Begin Moving Jumpers

WARNING

Before opening your system to change the jumper settings, turn the system power off by pressing the on/off push-button switch on the front panel, and unplug the AC power cord from the back of the chassis. Failure to disconnect power before opening the system can result in equipment damage.

CAUTION: An electrostatic discharge (ESD) can damage disk drives, add-in boards, and other components. Do all procedures only at an ESD workstation. If one is not available, you can provide some ESD protection by wearing an antistatic wrist strap attached to chassis ground on your system when handling components.

CAUTION: Operating the system with the covers removed can damage the system components. For proper cooling and airflow, always replace the covers before turning on the system.

System Baseboard Jumper Options

The system baseboard jumpers allow you to set specific operating parameters into the system.

A jumper is a small plastic-encased conductor (shorting plug) that slips over two jumper pins. To change a jumper setting, use a jumper removal tool or your fingers to remove it from its current location. Position the jumper over the two pins for the desired setting and press it onto the pins. Be careful not to bend the pins.

The illustration. shows the location of the baseboard jumpers. The table below lists the system baseboard jumpers and their factory default settings which are indicated with an asterisk (*).

Locations of Jumpers on the Baseboard

A, orientation of jumper pins 1, 2, and 3 for the baseboard jumpers.

Flash Memory Jumper E0190

The flash memory jumper enables the BIOS flash memory special recovery mode. The system BIOS can be corrupted, for example: when the update procedure is aborted due to a power outage. The flash memory contains a protected area that cannot be corrupted. Code in this area is used to boot the computer from drive A when the BIOS has been corrupted. After booting, the flash update utility is used to automatically recover the system BIOS from the BIOS recovery files on the diskette.

CAUTION: To reprogram the BIOS, you need to ensure that the flash reprogramming power jumper E0721. is on pins 1 and 2, the default position. Do not change the NVRAM jumper E0292 at the same time.

Note: The flash reprogramming power jumper E0721 must be in the +12 V position, pins 1 and 2, during flash programming. Moving the jumper to pins 2 and 3 disables the ability to write to the flash memory. However, the jumper should be left in the +12 V position, pins 1 and 2.

If you have mapped the BIOS of an add-in board to any part of the E0000H address range, you must either map it to another area or physically remove the board from the system before a recovery procedure can be completed. You do not have to remove add-in boards for normal BIOS updates.

Recover the BIOS by doing the following:

1. Observe the precautions listed under Before You Begin Moving Jumpers.

2. Remove the system covers as described in your product guide.

3. Ensure that the flash reprogramming power jumper, E0721, is on pins 1 and 2 (default). This puts +12 V on the program pin of the flash BIOS components.

4. Move the flash memory boot jumper, E0190., from pins 1 and 2 (default) to pins 2 and 3.

5. Replace the system covers as described in your product guide.

6. Insert the flash memory update diskette in drive A.

7. Connect the power cord to the system and turn it on. After the system boots successfully, the speaker emits a single beep and the recovery process starts, which takes about three minutes.

While in the recovery mode, there is no screen display on the monitor and the keyboard is disabled as the system automatically recovers the BIOS. Because there is no screen display, the recovery status is identified through these beep codes.


Beep Code	Message
2	Successful completion, no errors.
4	The system could not boot from the diskette. The diskette may not be bootable.
Continuous series of low beeps	The wrong BIOS recovery files are being used and/or the flash memory jumper E0721 is not set properly.

8. When the recovery process completes, the system speaker emits two beeps indicating a successful completion of the process.

9. Turn the system off and remove the covers.

10. Move the flash memory boot jumper, E0190, from pins 2 and 3 to pins 1 and 2 (default).

11. Replace the system covers.

12. Remove the flash memory update diskette from drive A.

System Baseboard SIMMs

The system baseboard contains four SIMM sockets: J0550 and J0551 (bank 0) and J0650 and J0651 (bank 1). Each socket can hold a single-sided or a double-sided, 80 ns, 36-bit fast-page SIMM module with a capacity of 1, 2, 4, or 8 MB. Each socket can also hold a singlesided or a doublesided, 70 ns, 36-bit fast-page SIMM module with a capacity of 16 or 32 MB. The baseboard will support up to 128 MB with four 32 MB SIMMs. Different-size SIMMs can be mixed in the system; however, they must be installed in like-sized pairs. Each pair can be of different size. You can install SIMMs in two or all four of the SIMM sockets (one or three installed SIMMs are not supported).

For information about the system memory map, see "System Baseboard"

For information about setting the SIMM memory bank jumpers, see "SIMM0 Jumper E0391" and "SIMM1 Jumper E0392"

When you install SIMMs in the sockets on the baseboard, you must start with socket J0550. When you remove SIMMs from the sockets, you must start with the first SIMM-filled socket closest to the CPU module connector J0770.

CAUTION: Mixing dissimilar metals may cause failures.

· SIMMs with tin-lead alloy plated edge connectors must be installed only in tin-lead alloy plated sockets.

· SIMMs with gold-lead alloy plated edge connectors must be installed only in gold-lead alloy plated sockets.

Note: Only SIMMs from JEDEC-compatible manufacturers have been tested for compatibility with the X-series deskside/LX system. Contact your sales representative or dealer for a list of approved devices.

Installing System Baseboard SIMMs

Baseboard SIMM Jumpers

The table below lists the jumpers and their factory default settings for each memory bank on the baseboard. If you install a pair of 16 MB or 32 MB SIMMs, you must move the memory bank jumper. from pins 1 and 2 to pins 2 and 3. In the figure, A shows the locations of the baseboard SIMM sockets.


Bank	Jumper	Position	SIMM Size	SIMM Speed
0 (J0550 and J0551)	E0391	1 to 2* 2 to 3	1, 2, 4, and 8 MB 16 and 32 MB	70 ns or 80 ns 70 ns
1 (J0650 and J0651)	E0392	1 to 2* 2 to 3	1, 2, 4, and 8 MB 16 and 32 MB	70 ns or 80 ns 70 ns

* Factory default setting.

Installing System Baseboard SIMMs

When properly installed, the SIMM module is oriented at an angle of 90° relative to the system baseboard; see F in the figure.

CAUTION: Use extreme care when installing a SIMM module. Applying too much pressure can break the retaining clips or damage the socket slot.

Note: SIMM modules are keyed and can be inserted in only one way.

1. Observe the precautions listed under "Before You Begin Moving Jumpers."

2. Remove the system covers, CPU module, and memory module (if installed) as described in your product guide.

3. Holding the SIMM module only by the edges, remove it from its antistatic package.

4. With the notched edge of the SIMM (E in the figure) facing towards the left edge of the system baseboard, position the SIMM at about a 45° angle relative to the socket on the baseboard (1 in the figure). The small notch in the middle of the bottom edge of the SIMM mates with the raised bump in the SIMM socket.

Beginning with socket J0550, insert the bottom edge of the SIMM into the socket and press in firmly on the SIMM until it seats correctly (1 in the figure).

5. When the SIMM seats correctly, hold it at each end and gently push the top edge towards the retaining clips (C in the figure) of the socket connector until the SIMM snaps into place (2 in the figure). The small horizontal posts by the retaining clips will pass through the holes in the ends of the SIMMs (F in the figure).

If the SIMM does not install correctly, gently push the retaining clips in opposite directions just enough so that you can pull away the top edge of the SIMM and try again.

6. Repeat the above steps to install the remaining SIMMs in the sockets. Fill the sockets in this order: J0550, J0551, J0650, and J0651.

7. Replace the CPU module, memory module, and system covers as described in your product guide.

8. Run the ECU to properly attribute the additional memory. Failure to do so may degrade the performance of your system.

Note: Running Setup will not attribute the memory.
