Appendix I: How to recover UEFI BIOS
Important Notes:
The emergency UEFI BIOS Recovery process is only used to rescue a system with
a failed or corrupted BIOS image that fails to boot to an OS. It is not intended to be
used as a general purpose BIOS flashing procedure and should not be used as
such. Please do not shutdown or reset the system while the BIOS recovery process
is underway or there is risk of damage to the UEFI recovery bootloader that would
prevent the recovery process itself from working. In no event shall Tyan be liable for
direct, indirect, incidental, special or consequential damages arising from the BIOS
update or recovery.
The BIOS Recovery file is named xxxx.cap, where the 'xxxx' portion is the
motherboard model number. Examples: 5630.cap, 7106.cap, 7109.cap, etc. Please
make sure that you are using the correct BIOS Recovery file from Tyan's web site.
BIOS Recovery Process
1.Place the recovery BIOS file (xxxx.cap) in the root directory of a USB disk.
2.Ensure that the system is powered off.
3.Insert the USB disk to any USB port on the motherboard or chassis.
4.
Power the system on while pressing “Ctrl” and “Home” simultaneously on the
keyboard. Continue to hold these keys down until the following Tyan screen is
displayed on the monitor:
