Dell R730 2.7.1 BIOS - ES CPU Support
#1
Hello,

I've purchased a Dell PowerEdge R730 server with BIOS 2.0.1, which has support for A0/A1 stepping ES Broadwell CPUs (CPUID 406F0). I need firmware 2.4.3 or newer because of a bug causing crashes and has therefore modified 2.7.1 and added the ES CPU Microcode from 2.0.1 BIOS. 

All well and good, the missing Microcode has now been added (replaced an entry I did not need), but there seems to be a block in the BIOS, with the following exact message:
Fatal Error. Broadwell A0/A1 stepping CPU not supported. Please replace CPU

I have found this error message in the BIOS, but I have no clue as to where I find the reference to this error, or where to disable it. Attached is the 2.7.1 (newest) BIOS with modified Microcode which has 406F0 CPUID added.

Original 2.7.1 BIOS:

Could anyone please help me out? Smile

It seems now that the error message is gone, but it does not continue to boot. No progress bar or anything else.

Please see attached image. There should, fairly quickly during boot display a progress bar at the bottom of the screen.

Are you sure there is nothing else you could do? It seems the error is removed, but it still freezes on the check. Could it be a problem with the microcode?

Could you try taking the original 2.7.1 firmware and add the microcode yourself? I may have done something wrong adding it. 

Guess microcode should be available here for the 406F0:

It's too difficult and too expensive work.

Okay. If you could give the error another go, this is how it looks like when frozen in boot. See attached image. Im sure there should be a way to skip it entirely.

Thanks for your time.

You can pass check but ES CPU can't be used by this BIOS.
Use old version BIOS or buy new CPU. It's cheaper that BIOS mod.
