using flashrom on supermicro board X11SSZ-TLN4F

[Kurt Jaeger]

Hi!

We've tried to install a new BIOS for a X11SSZ-TLN4F mainboard
from supermicro.

It can not be flashed using flashrom -- and says I should send
you a -V output. Here's the -V:

# flashrom -V -w X11SSZ0.602 -p internal
flashrom v1.2 on FreeBSD 12.2-RELEASE (amd64)
flashrom is free software, get the source code at https://flashrom.org

flashrom was built with libpci 3.7.0, LLVM Clang 10.0.1 ([e-mail]:llvm/llvm-project.git llvmorg-10.0.1-0-gef32c611aa2), little endian
Command line (5 args): flashrom -V -w X11SSZ0.602 -p internal
Using clock_gettime for delay loops (clk_id: 4, resolution: 1ns).

Found chipset "Intel C236" with PCI ID 8086:a149.
This chipset is marked as untested. If you are using an up-to-date version
of flashrom *and* were (not) able to successfully update your firmware with it,
then please email a report to [e-mail] including a verbose (-V) log.
Thank you!
