Unknown flash chip

[v0rIk]

I'm attempting to flash a modded bios file to add NVMe support on a 2014
motherboard.  When using the command:  Flashrom -p internal -r backup.rom
I get the error message SFDP has autodetected a flash chip which is not
natively supported by flashrom yet.  I ran the command   flashrom.exe -p
internal -vv -o output.txt   as suggested by the program.  The output file
is attached.

The specific mobo is ASROCK  AM1H-ITX with 32mb Ami Atpio IV BIOS

Thank you,
