**M1489/87 FinALi-486 PCI Chipset <Feb95
***Info:
ALi's M1489/M1487 PCI chipset is the most cost effective PCI solution
available. M1489/M1487 enables top-to-bottom PCI in 486 CPU systems,
offering superior price/performance for mainstream PCI-ISA systems.
M1489/M1487 highly integrates the DRAM controller, L2 cache control-
ler, Host, PCI, and ISA interface, as well as the standard ISA
functions: DMA controller, interrupt controller, timer/counter, RTC
(Real Time Clock), and keyboard controller. Additionally, M1489/M1487
incorporates the high performance Local Bus IDE allowing a system de-
signer to implement Local bus IDE with no additional cost. M1489/M1487
is a highly integrated solution requiring minimized TTL components,
enabling PCI-ISA designs at costs equal to or lower than comparable VL
Bus designs.
M1489 (Cache Memory PCI Controller: CMP) integrates the L2 cache con-
troller and the DRAM controller. The cache controller supports
write-back cache policies and cache size from 128K to 1M byte in an
interleaved or non-interleaved configuration. The DRAM controller
interfaces DRAM to the Host bus, PCI bus, and Link bus. M1489 can
support EDO 3/5V DRAM, standard DRAM, and flexible timing
select. M1489 also integrates intelligent Host to PCI, PCI to Host
buffer to achieve high performance. Also, M1489 provides the high
performance Local Bus IDE interface.
M1487 (ISA Bridge Controller: IBC) provides the bridge between the ISA
bus, PCI bus, and Host bus. IBC integrates the common I/O functions
found in today's ISA based systems: a seven channel DMA, two 82C59
interrupt controllers, 8254 timer/ counter, deep green function, and
control logic for NMI generation. IBC also has built-in 128 bytes RTC,
MC14069, KBC, and 7406. IBC also provides the decode for external
BIOS.

**W83759/A/F/AF Advanced VL-IDE Disk Controller <96
***Notes:...
***Info:
GENERAL DESCRIPTION
The W83759A is an advanced version of Winbond's popular VL-IDE
interface chip, the W83759. The W83759A retains all of the features
and compatibility of the W83759 (the chip meets the ANSI ATA 4.0
specification for IDE hard disk operation and the VESA VL-Bus 2.0
specification for PC local bus devices) while incorporating new
features to meet Enhanced IDE, SFF-8011, ATA-2, and Fast-ATA
specifications.
Supports Disk Capacity of Greater than 528 MB
The W83759A's driver can handle remapping from BIOS CHS mode to HDD
LBA mode. This scheme enables users to break the 528 MB per drive
barrier, allowing full use of BIOS INT13 CHS information in drives
with a capacity of up to 8.4 GB.
High Speed Host Transfer Rate
The W83759A supports Enhanced IDE PIO mode 3 and Fast ATA PIO mode 3
and 4 timing; jumper settings or driver programming can be used to
select the PIO mode and a 33 or 50 MHz VL-Bus clock. Different
programming timing can be selected for different drives in the same
system. The burst transfer rate is shown in the following table.
ATA PIO IDE COMMAND CYCLE BURST TRANSFER RATE IORDY THROTTLE
MODE TIME (nS) (MB/sec) CONTROL
0 600 3.33 Option
1 383 5.22 Option
2 240 8.33 Option
3 180 11.1 Required
4 120 16.6 Required
Dual IDE Channels
Like the W83759, the W83759A supports a secondary IDE address
(170h-177h/376h) and IRQ15 for applications with four hard disk
drives. Additionally, the primary and secondary channels can be
independently enabled or disabled by jumper settings or software
programming.
Non-disk IDE Peripherals
Because the command cycle can be programmed individually for each
drive and dual IDE channels are supported, non-disk IDE peripherals
(such as an ATAPI CD-ROM or tape drive) can be attached to the
secondary IDE without affecting the transfer rate of the ATA disk
drive. Sales of ATAPI IDE CD-ROMs are expected to grow rapidly as
these devices become a standard part of many users' desktop PC setup.
The W83759A provides all of the next-generation ATA-IDE requirements,
including support for high capacity disk drives, high speed host
transfers, multiple IDE peripherals, and non-disk IDE peripherals. It
makes high-performance, low-cost, easy-to-use IDE machines possible.
The W83759A is pin-to-pin backward compatible with the W83759. In
addition to the advanced features described above, the W83759A
supports automatic power-down, standby, and suspend APM power
management states for green PC applications. This new chip is packaged
in a 100-pin QFP.
