Some links on SuperMicro X10 and “PEI–Could Not Find Recovery Image…”

Posted by jpluimers on 2023/02/06

An X10 machine here hardly needs reboots, but at one point it did, and got a dreaded message “PEI--Could Not Find Recovery Image...“, so I started Googling.

  1. [Wayback/Archive] “pei” “could not find recovery image” – Google Search returned only one Russian thread: [Wayback/Archive] Восстановление BIOS на Supermicro X10SRi.
  2. Hard to read, I dug further with [Wayback/Archive] “PEI–Could Not Find Recovery Image…” – Google Search and [Wayback/Archive] “pei could not find recovery image” – Google Search, which both went for inexact matches: bummer.

The good news is that few people bump into this problem. The bad news is that the ones that do, usually do not find a way to solve it. For example:


What helped in retrospect, was using IPMI (which still worked), re-flash the most recent BIOS, then powered down the machine and rebooted: it worked.

Not sure if I will be so lucky next time, but via [Wayback/Archive] supermicro “could not find recovery image” – Google Search , I found the the idea from [Wayback/Archive] X9SRL-F POSTs only via BIOS recovery process | ServeTheHome Forums that might help: solder a new BIOS Flash ship. Definitely not for the fainthearted: [Wayback/Archive] Bios Recovery via Chip Reprogramming Supermicro X10SLM+-LN4F | ServeTheHome Forums.


I got at the BIOS programming via IPMI idea via the second set of searches above, which got me at [Wayback/Archive] Supermicro BIOS recovery – SUPER.ROM – Server Fault (thanks anonymous [Wayback/Archive] user303507):

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

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

This worked because all my SuperMicro mainboards are of the “-F” type and I had the key.

If you don’t have the key it can be generated, for instance with the bash script I published in Supermicro Bios Update – YouTube.

You can find back most letters and numbers SuperMicro uses at [Wayback/Archive1/Archive2] Motherboards (Intel UP) | Product Naming Conventions | Super Micro Computer, Inc. which has a few tables like this:

If you are on Mastodon as well as Twitter, then run these tools today, as soon they will likely stop working:
