Thx for replay :-). I was not sure wher to improve the code, in flashrom, coreboot or maybe seabios. Now I know :-)

P.S. I test command 'setpci -s 00:07.0 b2.w=8000' and this also make flashrom working but byte=e0 is from PCI config space table from vendor BIOS.

Thanks again, I will seek help on coreboot list.
