Phoenix BIOS
Introduction
The motherboard uses an Phoenix BIOS, which is stored in flash memory and can
be upgraded using a disk-based program. In addition to the BIOS, the flash memory
contains the Setup program, Power-On Self Test (POST), Advanced Power
Management (APM), the PCI auto-configuration utility, and is Windows 95-ready
Plug and Play. This motherboard supports system BIOS shadowing, allowing the
BIOS to execute from 64-bit onboard write-protected DRAM.
The BIOS displays a message during POST identifying the type of BIOS and the
revision code.
BIOS Upgrades
A new version of the BIOS can be upgraded from a diskette using the AFUDOS.EXE
utility that is available from the Viglen FTP site. This utility does BIOS upgrades as
follows:
•
Updates the flash BIOS from a file on a disk.
•
Updates the language section of the BIOS.
•
Makes sure that the upgrade BIOS matches the target system to prevent
accidentally installing a BIOS for a different type of system.
Note:
Please review the instructions distributed with the upgrade utility before
attempting a BIOS upgrade.
Using AWDFLASH to update the BIOS
The BIOS can be updated using the AWDFLASH.EXE utility in DOS environment.
