**82371AB PCI-TO-ISA / IDE Xcelerator 82371AB (PIIX4) 02/17/97
***Notes:...
***Info:
The 82371AB PCI ISA IDE Xceierator (PIIX4) is a multi-function PCI
device implementing a PCI-to-ISA bridge function, a PCI IDE function,
a Universal serial Bus host/hub function, and an Enhanced Power
Management function. As a PCI-to-ISA bridge, PIIX4 integrates many
common, I/O functions found in ISA-based PC systems-two 82C37 DMA
Controllers, two 82C59 interrupt Controllers, an 82C54 Timer/Counter,
and a Real Time Clock. In addition to compatible transfers, each DMA
channel supports Type F transfers. PIIX4 also contains full support
tor both PC/PCI and Distributed DMA protocols implementing PCI-based
DMA. The interrupt Controller has Edge or Level sensitive programmable
inputs and fully supports the use of an external I/O Advanced
Programmable interrupt Controller (APIC) and Serial interrupts. Chip
select decoding is provided for BIOS, Real Time Clock, Keyboard
Controller, second external microcontroller, as well as two
Programmable Chip Selects. PIIX4 provides full Plug and Play
compatibility. PIIX4 can be configured as a Subtractive Decode bridge
or as a Positive Decode bridge. This allows the use of a subtractive
decode PCI-to-PCI bridge such as the Intel 380FB PCIset which
implements, a PCI/ISA docking station environment.
PIIX4 supports two IDE connectors for up to four IDE devices providing
an interface for IDE hard disks and CD ROMS. Up to four IDE devices
can be supported in Bus Master mode. PIIX4 contains support for
"Ultra DMA/33" synchronous DMA compatible devices.
PIIX4 contains a Universal Serial Bus, (USB) Host Controller that is
Universal Host Controller interface (UHCI) compatible. The Host
Controller's root hub has two programmable USB ports.
PIIX4 supports Enhanced Power Management, including full Clock
Control, Device Management for up to 14 devices, and Suspend and
Resume logic with Power On Suspend, Suspend to RAM or Suspend to Disk,
It fully supports Operating System Directed Power Management via the
Advanced Configuration and Power Interface (ACPI) specification.
PIIX4 integrates both a System Management Bus (SMBus) Host and Slave
interface for serial communication with other devices.

**5591/5592/5595 (David) Pentium PCI A.G.P. Chipset <01/09/98
***Info:
The SiS5591/5592 SiS5595 glueless P5 A.G.P. chipset provides a high
performance/cost index Desktop/Mobile solution for the Intel Pentium
P54C/P55C, AMD K5/K6, and Cyrix M1/M2 A.G.P. system.
The SiS5591/SiS5592 A.G.P./PCI controller integrated the Host-to-PCI
bridge, the L2 cache controller, the DRAM controller, the Accelerated
Graphics Port interface, and the PCI IDE controller. The L2 cache
controller can support up to 1 M P.B. SRAM, and the DRAM controller
can support EDO/FP/SDRAM memory up to 768 MB with optional ECC or
parity check function. The A.G.P. 1.0 compliance interface supports
both 1X, and 2X speed mode with sideband address capability. The
built-in fast PCI IDE controller supports the ATA PIO/DMA, and the
Ultra DMA/33 functionality.
SiS5591 and SiS5592 have some pin-out switching to facilitate the
main-board layout. SiS5591 pin assignment is based on the ATX form
factor, and SiS5592 pin assignment is based on the NLX form
factor. Beside the pin-out switching, SiS5591 and SiS5592 is totally
the same on the internal logic circuit.
The SiS5595 PCI system I/O integrates the PCI-to-ISA bridge with the
DDMA, and Serial IRQ capability, the ACPI/Legacy PMU, the Data
Acquisition Interface, the Universal Serial Bus host/hub interface,
and the ISA bus interface which contains the ISA bus controller, the
DMA controllers, the interrupt controllers, and the Timers. It also
integrates the Keyboard controller, and the Real Time Clock (RTC). The
built-in USB controller, which is fully compliant to OHCI (Open Host
Controller Interface), provides two USB ports capable of running
full/low speed USB devices. The Data Acquisition Interface offers the
ability of monitoring and reporting the environmental condition of the
PC. It could monitor 4 positive analogue voltage inputs, 2 Fan speed
inputs, and one temperature input.
