Looks like you have that backwards. If "lspci -vnn" reports 1002:4752 then you should set OPTIONROM_VENDEV_1 to "0x10024752". > Notice the byte at 35b0.

I committed a couple of more debug statements to the option rom scan. Can you do a "git pull", set the debug level to 6, and provide the output? > PS I think a comment about the order of OPTIONROM_VENDEV_* would be > helpful, since it is device then vendor ID.

With CBFS that should be a thing of the past. -Kevin -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
