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 can no longer boot due to a corrupted BIOS. DO NOT
reprogram (re-fl ash) the BIOS if your system is running properly.
B-1 Recovery from USB Device
If the BIOS fi 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 USB hard disk drives are NOT supported at this time. Below is the 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 im-
age into a USB fl ash device or a writable CD/DVD disc's Root "\" Directory.
Rename the downloaded fi le to "super.rom", so the recovery process can
recognize and read the BIOS binary fi 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 fi rmware
is being reprogrammed. The screen will also display a message as shown
below. DO NOT INTERRUPT THIS PROCESS!
