Other one, maybe wrong thread… because of Supermirco.
Having some X9, X10, X11 Supermicro Server boards.
BIOS of them is a bit tricky:
some don’t habe EFI Graphic modules for Intel (because most Xeon don’t habe IGPUs, but some e.g. C226 have support for that CPUs),
but they have Graphic GOPs for IGPUs
nearly all Boards have additional microcodes for CPUs which do not fit into sockets = silly Supermicro
Did add iGPU efs module as last DXE files with UEFItools, also added NVMe-ffs. Then updated microcode, LAN, GOPs and RSTe with UBU.
Flashed with AMIflash and after successfull flash ended in recoverymode of bios (bios showing “entering recovery” then restarting in a loop).
Renamed modded BIOS to SUPER.ROM and put it onto root of stick (FAT32),
Mainboard restartet many times, each time again going into recovery (maybe each time a bit further).
After around four restarts BIOS-Menu for Recovery appeared, selectet flash recovery bios and so flashed modded bios again.
After flashing modded bios in recovery mode, modded bios was accepted and mainboard now has a running system.
First tried it with a X10 mainboard with defect LAN (no problem if brickage), then flashed all other X10, then X11 and then X9 without problems.
Now all boards running well under ESXi 6.5
