Appendix C - BIOS Recovery
The recovery procedure described in this section is to be used only when you are
advised by your Supermicro Technical Support representative, or in cases of emer-
gencies where the system no longer can boot due to a corrupted BIOS. DO NOT
re-program (re-ash) the BIOS if your system is running properly.
C-1 Recovery Process from a USB Device/Drive
(Recommended Method)
If the BIOS le 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. Below is a two-part
procedure to recover the BIOS:
Part 1: Boot Sector Recovery Process
1. Using a different system, download and copy the correct BIOS binary image
into a USB ash device or a writable CD/DVD disc's Root "\" Directory. Rename the
downloaded le to "super.rom", so the recovery process can recognize and read
the BIOS binary le.
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 rmware is being
reprogrammed. The screen will also display a message as shown below. DO NOT
INTERRUPT THIS PROCESS!
