D. Flash BIOS Programming Utility
Flash BIOS is featured on DC-390 series with the exception of DC-390 (The word
“FLASH” on the adapter’s BIOS chip indicates flash support) .
Updating the DC-390U/F/U2B/U2W BIOS Code is made easy with the TRMFLASH.EXE
Utility, which can be found in the <BIOS> directory of the driver disk. Since the DC-390U/F
(board versions 1.1/2.2 and later) and DC-390U2B/U2W feature FLASH BIOS, it is not
necessary to change the actual BIOS chip in order to upgrade the SCSI BIOS. The user can
simply re-program the old BIOS using the TRMFLASH.EXE Utility as follows:
1.
First, boot the system with DOS or to “Safe Mode” under Windows 95. If you are
booting DOS from a hard drive or floppy disk, press [F5] when the message “Starting
MS-DOS…” appears on the screen. If you are booting Windows 95, press the [F8] key,
and select the “Safe mode command prompt” option. This will assure that the system is
running in
“
real mode
”
with
no device drivers loaded
.
This is the only correct way to
run the TRMFLASH Utility program.
2.
There are (2) important files needed to re-program the BIOS. The first is
“TRMFLASH.EXE” which is the FLASH BIOS Programming Utility. The second file
needed is the updated “BIN” file which contains the actual BIOS code. This file will
have the extension [.bin], such as “INT13.BIN”. Make sure these files are on the diskette
or hard drive in the same directory.
3.
Start the TRMFLASH Utility by changing to the directory where the two required files
exist and typing: TRMFLASH and pressing [ENTER].
4.
The TRMFLASH Utility Screen appears. You will be asked for the file name to
program. Type in the name of the new BIOS (.bin) file and hit [ENTER].
5.
The program will then ask if you want to backup the old BIOS. This is recommended in
case there are any problems with the new “.bin” file. Enter the name of the new backup
file (such as “backup.bin”) and press [ENTER].
6.
At this time the system will prompt you for final confirmation before beginning
programming. The Utility can be aborted at this time by hitting “n”. To begin
programming, hit “y”…
When the Flash programming starts, a bar indicator will show the progress of the
programming operation. After successful completion, hit the reset button or power off the
computer.
After BIOS upgrade, there will be no <<<Press F2 …>>> message shown along with DC-
390’s BIOS message during next bootup. To enable this display you need to execute
\DOS\UTIL.EXE from the DOS/NetWare driver diskette and set the “F2 or F6 Function
During Bootup” in “Set Adapter Options” to “Enabled”.
