Recovering the BIOS

If you encounter a problem while you are updating the BIOS, such as a power outage, the BIOS update may not be successful. If the system continues to try to boot from the new, corrupted BIOS, you can boot the system in recovery mode.

This should only be done if other BIOS recovery methods have failed. In recovery mode the recovery code will load working BIOS code from the recovery media and use it to boot to the EFI shell. The minimum number of peripherals will be enabled.

To recover the BIOS:

1 Create the BIOS recovery media:

■Create a DOS-bootable USB flash memory device (the recovery media)

■Copy the flash BIOS update application (iflash64.exe) to the root directory of the recovery media

■Copy the BIOS update file to the root directory of the recovery media

■Edit the autoexec.bat file on the recovery media to automatically run the BIOS update. For example, add this line to the autoexec.bat file:

iflash64.exe shw4.cap /u /ni
