C-1 Recovery Process from a USB Device/Drive
(Recommended Method)
If the BIOS file is corrupted and the system is not able to boot up, this feature will
allow you to recover the BIOS image using a USB-attached device. A USB Flash
Drive or a USB CD/DVD ROM/RW drive may be used for this purpose. Please note
that a USB Hard Disk drive is NOT supported at this time. Follow the procedures
below recover the BIOS.
Part 1: Boot Sector Recovery Process
1.
Using a different system, download and copy the correct BIOS binary im-
age into a USB flash device or a writable CD/DVD disc's Root "\" Directory.
Rename the downloaded file to "super.rom", so the recovery process can
recognize and read the BIOS binary file.
2.
Insert the USB device that contains the new BIOS binary image ("super.rom")
and power the system down.
3.
While powering on the system, press and hold <Ctrl> and <Home> simultane-
ously on your keyboard until the USB device's LED indicator comes on. This
will take a few seconds or up to one minute.
4.
Once the USB device's LED is on, release the <Ctrl> and <Home> keys. The
system may generate beep codes to indicate that the BIOS ROM firmware
is being reprogrammed. The screen will also display a message as shown
below. DO NOT INTERRUPT THIS PROCESS!
5.
When the Boot Sector Recovery Process is complete, the system will reboot
automatically, and you will see a checksum error on your screen.
