********BIOS Recovery procedure*******



When you performed the Flash reprogramming, make sure you do not reboot or power down until the updates is completed
( typically within 5 minutes).  If you fail to heed this procedure, 
you will be left with a system that has a corrupted BIOS.  
In the unlikely event that a Flash upgrade is interrupted catastrophically, 
the BIOS may be left in an unusable state. However, SUPERMICRO's Flash ROMs have a special BIOS Recovery procedure 
that can be performed. Recovering from this condition requires the following steps. 


1. Copy the H8xxxxx.xxx file from BIOS package and save into a USB drive
2. Rename the H8xxxxx.xxx file to super.rom
3. Install the USB on the MB and remove other bootable device
4. While Power on the system, hit "ctrl + Home" keys several times
5. The USB LED turn on, but the screen is blank and some long beeps from onboard buzzer.
6. After the BIOS recovery is completed, 4 quick beeps and then system will reboot.
7. “CMOS Checksum” message will show, press F1 go into BIOS setup and then load optimal default settings or your custom BIOS setting.
8. Save setting and reboot system.
