IV. BIOS SOFTWARE
Flash Memory Writer Utility
This motherboard comes with a diskette which contains the following files:
README.TXT
A Readme text file containing information about the utility. To access or print out
the contents of this file, you can use any text editor program.
DMICFG.EXE
Desktop Management Interface Utility. See section V for basic instructions.
T25Ixxxx.AWD
A BIOS file for this motherboard. xxxx here is a 4-digit version number; larger
values denote newer BIOS versions, while smaller numbers denote older versions.
PFLASH.EXE
This is the Flash Memory Writer utility. The Flash Memory Writer utility updates
the BIOS by uploading a new BIOS file to the programmable flash ROM chip on the
motherboard. This BIOS file is included in the support diskette, and may be newer
than the BIOS on the motherboard. To determine whether or not the provided BIOS
file is newer than the current motherboard BIOS, compare the diskette's BIOS file
name with the last four numbers of the code displayed on the upper left-hand corner
of your screen during bootup. If the number of the BIOS file in the support diskette
is larger, continue with this section to reprogram the motherboard BIOS. If the
number is smaller, do not continue with this Flash Memory Writer section.
Before reprogramming the motherboard BIOS, you must first:
1. Enable "Boot Block Programming" (see page 12).
2. Make sure the system is running in real mode. This utility will not operate if
the system is under protected mode or virtual mode. This means that you
cannot reprogram the motherboard BIOS under the Windows environment or
with any memory management software, including HIMEM.SYS. If you have
any memory management software running, disable them first. The following
describes the easiest way to ensure that your system memory is free from these
programs:
