Appendix E: Updating the System BIOS

Updating the System BIOS
The Micronics motherboards are designed so that the BIOS can be
reprogrammed using a BIOS file. You can easily FLASH a BIOS by
following the steps below:
1) After downloading the appropriate BIOS file from our BBS,
extract it to a bootable MS-DOS 6.X diskette.
2) Reboot your system with the MS-DOS 6.X diskette in the A:
drive. To make sure a clean DOS environment is loaded, press
the F5 key while “Starting MS-DOS” is displayed. After the
system has rebooted, the cursor will appear at the A:> prompt.
3) Now you can run the FLASH utility. The filename will be either
“FSH” (or FSH20, FSH20G, etc.) or “PHLASH.” Type this
filename at the A:> prompt (but don’t include its extension),
followed by a space and the BIOS ROM image’s filename. This
file will be included in the download and has a file length of
about 131K. For example, to update the M54E2 to BIOS version
05, you would type:
PHLASH M54E2.05 [ENTER]
4) Once the FLASH process has begun, select [Y]es, if prompted, to
allow auto-sensing of the part (the FLASH chip itself).
5) After the update process has completed and the system reboots,
verify that the new BIOS version appears on-screen. If you have
problems during this process, or if you have questions about the
procedure, please call Technical Support.
NOTE: If the BIOS is somehow erased or doesn’t seem to accept the
upgrade, you can have your original BIOS chip reprogrammed
manually by Technical Support. There is a $29.95 fee for this
service, which includes shipping charges to send your FLASH
EPROM chip back to you. Also, a preprogrammed FLASH EPROM
chip can be purchased from Technical Support for $50.00. Overnight
shipping costs an additional $10.00. (Price and availability subject to
change.) If you prefer to send your system board in for the upgrade,
the RMA department offers this service free of charge if your system
board is under warranty.
