CB7268 74 Version: 1.1
8.8 BIOS update
The "DecdFlsh" program and a bootable medium with the latest BIOS version are used if the BIOS needs to
be updated. When doing this it is important to start the program from a DOS environment without a virtual
memory manager such as "EMM386.EXE". If such a memory manager is loaded, the program will abort with
an error message or cause a crash.
DecdFlsh is a program for the automatic updating of the BIOS on all boards with AMI-BIOS. All files
contained in the zip file must be unpacked into a directory, from where
DecdFlsh Bios-Dateiname
calling takes place. The name of the BIOS file and its length are checked. The BIOS will now be
programmed. DecdFlsh also exists as a UEFI tool for calling from the UEFI shell.
A running Flash procedure must never be interrupted, as otherwise the BIOS on the board will be destroyed.
The Flash procedure takes about 75 seconds. The necessary firmware update takes place automatically.
Avoid damage due to incorrect update execution!
If the BIOS update is performed incorrectly, the board may become unusable. Therefore a BIOS up-
date should only be done if the corrections / additions that the new BIOS version brings with it are
really needed.
Before a planned BIOS update, it is essential to ensure that the BIOS file to be reloaded is really re-
leased for exactly this board and for exactly this board version. If an inappropriate file is used, the
board will inevitably not boot afterwards.
