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 maybe cause 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.
