BIOS Recovery
When you boot up the computer and you hear one long beep, followed by a shorter one, the system BIOS is
damaged. This may be caused by an interruption during a BIOS flash procedure (e.g. a power outage) or a
corrupted BIOS code, which will cause the system to go into an unbootable state. You need to access and
execute the boot block program to reboot the computer and recover the regular BIOS code.
Note the following when restoring the BIOS settings:
•
Make sure the computer is connected to a UPS unit during the BIOS recovery process.
•
The BIOS recovery media should be prepared in a computer running the Windows OS. A USB flash drive
can be used.
Creating the BIOS Crisis Recovery Disk
1.
Set up a computer running the Windows operating system and connect the BIOS recovery media.
2.
Copy the target BIOS ROM file to the BIOS recovery media and rename it as “RCVBOOT.CAP”.
3.
Eject the BIOS recovery media from the computer.
Performing a BIOS Recovery
1.
Shut down the system with failed BIOS.
2.
Put the BIOS ROM file (it may exist at \ROM\xxx.CAP) to a USB storage.
3.
Rename BIOS ROM file to RCVBOOT.CAP (i.e. P11-A0.CAP to RCVBOOT.CAP)
4.
Plug the USB storage to the system.
5.
Press the power button to turn on the system.
The system will now execute the BIOS recovery process. You will hear a long beep followed by a short beep.
6.
Select
Proceed with flash update
to start recovery.
NOTE
This procedure is only applicable when the boot block section is still valid.
