[flashrom] Update bios (not full flash) with flashrom

[Skoll RC]

Hi everyone,

I would like to update my GA-8I915P-MF's bios with flashrom but Gigabyte only provide updates and no full bios so when I try to update with
flashrom -p internal -w 8i9pmf.f2 I have an error message: Error: Image size (262144 B) doesn't match the flash chip's size (524288 B)!
How can I fix it?

thx
