Appendix E: BIOS Recovery
D-1
Appendix D - 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-flash) the BIOS if your system is running properly.
D-1 Recovery Process from a USB Device
(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 may be used for this purpose. Please note that a USB Hard Disk drive is
NOT supported and COM1 is the only serial port recognized. 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 flash device'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!
