Flashed with awdflash works.
Is the bootblock in the downloaded image intact/present? You can use bios_extract: http://cgit.freedesktop.org/~libv/bios_extract What happens when you reset the CMOS/ESCD data after flashing with flashrom? awdflash does that with the /cp parameter, see http://www.plasma-online.de/textual/howto/flash_award.html > - Image flashed with awdflash, dumped from bios chip using flashrom and > writing back using flashrom (to an empty chip also) works (machine does > POST and I can boot my OS) > - I haven't tried writing flashrom dumped image using awdflash. > - If I write a dumped image using flashrom and later do a flashrom -v it > will complain about some difference.
