Chapter 3 BIOS Setep
AMI BIOS upgrade:
It is true that hardware and software are upgrading all the time. When your IPC can not
support the newest processor (for example), you should upgrade the BIOS to try to keep up
with the latest technology. Upgrading (or flashing) the BIOS is not an easy attempt. To make
sure upgrade succeed, please follow the instruction below:
Set jumper JAV as open
Afudos.exe is the program for BIOS to modify and upgrade，need to be run in DOS mode.
Step1: use boot disk load DOS, run Amiflash.exe and write the newest file: XXXX.ROM into the
Flash IC.
Order format: A:\ Afudos XXXX.ROM
If you need to add other parameters, please add <space>/? after the order format.
Example：Afudos 4850I101.rom /P /B /C /N /X
Remarks:
1. Upgrading BISO may cause your system crash, so please operate carefully.
2. Please use the upgrading program in the CD-ROM provided by us
3. Please do not power off or reboot the system when upgrading, otherwise, the BIOS maybe
be damaged.
4. Please backup your BIOS before upgrading
