5.8 BIOS-Update
If a BIOS update needs to be done, the program “DecdFlash” as well as a bootable medium which
contains the newest BIOS version is used for this. It is important, that the program is started from a DOS
environment without a virtual memory manager, for example “EMM386.EXE”. In case such a memory
manager is loaded, the program will stop with an error message.
DescdFlash is a program which provides automatic BIOS updates on any AMI-BIOS boards. All files need
to be copied from the .zip-file in another directory.
The system may not be interrupted during the flash process, otherwise the update is stopped and the
BIOS is destroyed afterwards.
The program should be started as follows:
DecdFlsh BIOS-Filename
After checking the name of the BIOS file and its length the BIOS will be programmed.
The flashing takes nearly 75 seconds. The firmware will get updated automatically.
A faulty BIOS-Update process may cause damages on the board!
Updating the BIOS in an improper way can render the board unusable.
Therefore, you should only update the BIOS if you really need the
changes/corrections which come with the new BIOS version.
Before you proceed to update the BIOS you need to make absolutely sure that you have the right
BIOS file which was issued for the exact board and exact board revision that you wish to update. If
you try to update the BIOS using the wrong file the board will not start up again.
