      that's actually surprisingly well-written, and you can even build it for EFI

      I like 44. Program manufacturing information and 33. Erase non-volatile adapter storage. I bet some combination thereof will solve all the pesky crossflashing problems. I have both an IBM M5010 and a Dell PERC... wonder if I can completely rewrite the latter.

      as far as I can tell building this for EFI and enabling expert mode should just naturally allow overriding all VID/PID checks

      ManufacturingPage2 seems to contain the first chunk of what I called the SBR. I wonder if that really is the SBR itself or some kind of mirror in NVRAM (which would explain the complaints from the other tools even after you write SBR).

      "44. Program manufacturing information" seems to write all that stuff. I wonder if it writes just NVRAM or also SBR.

      Oh, and that magic byte that fixed half the ports on my Fujitsu board? It's called HardwareConfig. Surprise.

      I'm really tempted to mess with the Dell adapter in my backup server now, see if I can convert it to vanilla firmware straight from Linux. Even though it's a 3 hour train ride away. YOLO, right? It's not used for the boot drives...

      Also I bet this can be ported to run in "DOS/EFI" mode (raw access) under linux (with pcilib) to recover bricked adapters without the kernel driver being involved.

          yup! To be honest I was surprised that it used the Linux driver, seems superfluous

          You want to use the Linux driver when it's loaded (otherwise you're stepping on its toes; this thing is supposed to be usable on live systems) but it makes no sense not to offer the direct option as well.
