Mainboard Supermicro, M11SDV-8C-LN4F, does not find EEPROM

[Kurt Jaeger]

Hi!

I've tried to update the BIOS on the M11SDV-8C-LN4F mainboard,
running a very recent FreeBSD:

FreeBSD tst.opsec.eu 13.0-CURRENT FreeBSD 13.0-CURRENT #0 r364846: Thu Aug 27 05:10:55 UTC 2020     [e-mail]:/usr/obj/usr/src/amd64.amd64/sys/GENERIC  amd64

This is the output of the command:

flashrom -w M11SDV0.630  -p internal
flashrom v1.2 on FreeBSD 13.0-CURRENT (amd64)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 4, resolution: 1ns).
Found chipset "AMD FP4".
Enabling flash write... FCH device found but SMBus revision 0x59 does not match known values.
Please report this to [e-mail] and include this log and
the output of lspci -nnvx, thanks!.
Could not determine chipset generation.PROBLEMS, continuing anyway
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

Attached is the pciconf -lvb output (FreeBSD does not have lspci).

If it helps, I can try to boot some linux on that system.
