as requested for discussion, here is a modded/updated version for your particular board.
EFI_ROM stock:
EFI_ROM modded:
microcode update:
manual NMVe mod:
The modded BIOS is based on the version 3802 which is the lastest published version for your motherboard.
NOTE the existing Intel ME: 8.0.2.1410 should be upgraded to → 8.1.70.1590 updated in ME Region PRIOR to BIOS flashing Edit Feb 16, 2021
Note the Intel Management Engine version in the photo above!
Further observe the non empty padded files; which implies the NVMe mod should be done using MMTool 4.50.0023.
** Your board should be upgraded to ME 8.1.70.1590 before you update the BIOS. Copy the contents of IntelME.zip to the root of a DOS boot drive, boot from it and run flash.bat (doing this in advance speeds up the BIOS flashing procedure quite a bit and prevents possible ME version clash issues).
So I just flashed this onto my ASUS Z68V PRO Gen3 board…after flashing the IntelME update…rebooted but if I select UEFI Boot etc the PC won’t boot and I can’t get back into the BIOS I have to reset the CMOS…so what gives…the new modded BIOS I thought was supposed to allow UEFI boot from M.2 SSDs etc.
Thanks for replying…my other non Pro board boots fine in uefi mode with the modded 3603 bios…but the pro after flashing the intelME update and the .rom in this thread…in the first post…won’t even save in the bios …bios locks up and I have to reset back to default with a CMOS reset. Both boards have unlocked CPUs running closed loop water blocks so I’d like to keep them going … anyway thanks again.
I reread the install OS setup stuff you linked to…I think that has answered an issue I had on my p8z68v-gen3 board, the one that does boot with uefi mode enabled…so thanks for reminding me of that thorough detailed explanation…I only read it once when I first joined and most of it went over my head…
