Firmware Update Utility-AMI Flash Utility
AMI Flash Utility can update BIOS through local interface.
1Boot into DOS/Microsoft Windows.
2Execute C5220BIOS(version).exe.
NOTE: DOS does not support long file names. To use a file under DOS mode, rename it to fit the required file structure before executing the file.
BIOS Recovery Mode
The BIOS has an embedded recovery technique in the 'boot block'. In the event that the BIOS becomes corrupt the boot block can be used to restore the BIOS to a working state. The routine is called when the 'system block' of the BIOS is empty or corrupt. The restore routine when called accesses the USB drive looking for a file named 5220BIOS.ROM.
This is the reason the USB drive light comes on and the drive appears to be in use. If the file (5220BIOS.ROM) is found it is loaded into the 'system block' of the BIOS to replace the corrupted information.
To restore your BIOS, copy the most recent version of your system board’s BIOS file to a USB key and rename it 5220BIOS.ROM.
BIOS Recovery Flow
1Rename the ROM file to 5220BIOS.ROM and copy to the USB device.
2Short the recovery jumper (JP11).
3Power on the system.
