I have a Supermicro X9SCL+-F motherboard that I flashed a beta BIOS to, then the flash went bad when I tried to flash back to the latest stable. I am attempting to recover using their SUPER.ROM recovery from a flash drive without success.

I read in the manual that if I hold down Ctrl +Home  while powering on the server I can do a BIOS recovery from a flash drive.

I hold down those keys, hear the desired two beeps and I can see the activity LED on the flash drive activate. Unfortunately, instead of the monitor turning on and allowing a BIOS recovery as the manual indicates, I hear five beeps, followed shortly after by 3 beeps. I grabbed the latest BIOS from their site ( and extracted it to my flash drive and renamed it to SUPER.ROM. Their instructions are not clear if any ROM can serve as the SUPER.ROM file, or if I need a special SUPER.ROM file to initiate the recovery at which time I can supply a known good ROM.

Does anyone have any expertise in ROM recovery for Supermicro boards? Am I missing some key step? Can any known good ROM file function as the SUPER.ROM file for recovery?

I had to do this on a laptop a few times. When I did it, I kept being impatient and not waiting for the BIOS to restore the firmware and kept interupting it. It took a good 90 seconds for it to finally finish. It is curious to note that I didn't get any display other than a flashing num lock and caps lock lights. I can't answer your question about the name of the file specifically, but I do know that in my case the name was very important. – MikeAWood Jun 2 '12 at 0:51
The reason why there is no display is because you need a working bios to initialize the display hardware; the special recovery routine probably has just enough code to do its job. I haven't done this procedure in a long time (when I did, it read the recovery BIOS from a floppy!). I'm pretty sure any BIOS can be used but check with support if you're unsure. I always found the Supermicro email support to be helpful. – JGurtz Jun 6 '12 at 15:45

I finally got some answers from their tech support, though it didn't end up working and it honestly sounded more like "suggestions" than actual facts... regardless:

  • The five beeps likely means "process failure" in this case - whatever that means.
  • The three beeps could possibly mean RAM failure. I strongly doubt this as I let the RAM burn in with memtest+ for about 72 hours. Doesn't mean something isn't wrong - just doubtful.
  • For what it is worth, I was told that the format of the flash drive didn't matter between FAT12, FAT16 and FAT32 - I tried both FAT16 and FAT32 without success.
  • I was told that the name of the file is case sensitive, and should be SUPER.ROM in all caps.
  • I was also told that any known good BIOS image could be used as a source, just renamed to SUPER.ROM

I hope this helps someone else in the future. After about six weeks of emailing back and forth with their tech support and attempting different things with this board - I finally gave up troubleshooting it and just sent it in for an RMA and purchased a different board. Anyone want to buy a refurbished Supermicro board?

What file system did you use if nothing of FAT-XX works? – adnako Jul 20 at 13:42
Thanks for answer, my war is still continuing. Now I'm trying FAT16, since RMA is very far from me ... – adnako Jul 21 at 7:18

Get mainboards with a "-F" in the product name. Then you have IPMI and can even flash a faulty BIOS. It requires a key from Supermicro to activate this feature which is not for free, but you can order a demo key which helps in this case. You get it relatively quick within 1-3 workdays.

The 2nd flash area can also be fully impacted by a faulty flash process, therefore the trick with Ctrl+HOME does not work.

At the end nothing will work, as a faulty flashed BIOS results in a fully dead machine. All that helps here is to go via IPMI. Then you are glad having spend the xx bucks more on a board with IPMI. Otherwise you would have to send the board damaged to supermicro.

This question is a bit old, so my memory is perhaps not perfect of this event any longer, but as I recall I could not reach the board via IPMI either. I believe the IPMI implementation on this board will only allow for IPMI firmware flashes not BIOS upgrades though. I would have to double check. – Goyuix Aug 7 at 21:45
