Chapter 1: Introduction
This manual documents the AMIBIOS for the Intel 82430HX Triton II PCI Chipset based on the
AMIBIOS 95 Core AMIBIOS. This AMIBIOS is designed for a Pentium-based ISA computer
system. This AMIBIOS also supports IDE on the PCI local bus.
Plug and Play Support
This AMIBIOS supports the Plug and Play Version 1.0A specification.
PCI Bus Support
This AMIBIOS also supports the Intel PCI (Peripheral Component Interconnect) local bus specifi-
cation. Please see the Intel technical documentation for additional information.
SRAM Cache Memory Support
This AMIBIOS supports asynchronous and burst SRAM. This AMIBIOS automatically detects the
cache memory type and size.
DRAM Support
EDO (Extended Data Out), FPM (Fast Page Mode), and ECC (Error Correction Code) DRAM
memory is supported.
Flash ROM Support
Flash ROM support is also included in this AMIBIOS.
The Intel 28F001BXT flash EEPROM is supported. To reprogram the flash ROM, make an update
BIOS ROM file and name the file AMIBOOT.ROM. Copy this file to a floppy. The end user can
insert the floppy drive in drive A: and press <Ctrl> <Home> while powering on.
PCI SCSI BIOS Support
The Adaptec 7880 PCI SCSI support is included in the system BIOS for the onboard SCSI PCI
controller. This AMIBIOS gains control if a Adaptec 7880 SCSI device is detected.
System BIOS
The BIOS is the basic input output system used in all IBM® PC-, XT-, AT®-, and PS/2®-
compatible computers. The AMIBIOS is a high-quality example of a system BIOS.
