Does your system post? If it does just use ipmitool to locally reset password - I had an Linux usb flash drive with ipmitool installed just for that purpose - to reset admin password on ipmi of my servers when needed.

Ouch. I don’t even think I have any Naples based processors left in my collection. Is this an issue with Gigabyte boards or is it a generic AMD issue that BIOS can serve only one generation of Epycs?
the board is rev. 1.x = only Naples. BIOS chip 16mb
but can be flashed to Rome with part of BIOS from rev 3.x
Can anyone please help to update MZ31-AR0 (rev. 1.1) to server_mb_bios_MZ31-AR0_R34_F22 (Rome/Milan).
As I have 16 384 kB chip I can only flash Rome or Milan (not both simultaneously supported in my case).
So, how can I do this? BMC says:

So, I need a programmer to flash it?
server_mb_bios_MZ31-AR0_R34_F22
R34 = Rome
F22 = Naples
server_mb_bios_MZ31-AR0_M04_R32
R32 = Rome
M04 =Milan
you need RBU file:
check this

Do you happen to have rome BIOS that also works on ES epycs? , I couldn't find BIOS with old agesa versions.server_mb_bios_MZ31-AR0_R34_F22
R34 = Rome
F22 = Naples
server_mb_bios_MZ31-AR0_M04_R32
R32 = Rome
M04 =Milan

i can mod a flash_F.rom or flash_R.rom to a RBU file. which do you need ?
check this
I was able to find MZ31-AR0_R03_F16.zip, not sure how to do the flashing part as I only have SOP8 now, I think Zhang Said that rev 2 rome part would be flashed as they have some sort of signature check. I would have to somehow cheat BMC and I am not sure about where to start.
just added flash_R.RBU in RBU folder
is this going to bypass the signature check? I am also not sure which agesa version this BIOS has. hopefully lower enough for it to work with ES epycjust added flash_R.RBU in RBU folder
read the rel.notes inside. AGESA PI version: RomePI 1.0.0.1
RBU is accepted by WebGUI
I see, I think something odd is wrong with the board, it keeps showing old CPU 7282 and one stick of RAM eventhough I tried resetting BMC along with CMOS, I tried RBU Update and it doesnt work no matter which version I use. I also noticed that IPMI shows bios recovering right after I log in.
pls note: you need full successful POST to update the inventory. if not you see last working config.
I've never had this work on 2 different sets of Supermicro boards. Inventory never updates, but system runs fine so I'm not bothered about it. I'm sure there has to be some BIOS or IPMI option that's just blocking it.
