Hi all,
I just followed the instruction of http://www.coreboot.org/SeaBIOS concern about #define CONFIG_OPTIONROMS_DEPLOYED 0 ,
But It can not show the video output correct. Maybe something wrong with it.

If you have a built-in VGA device that requires an option rom from flash, then you also need to set something like:
#define OPTIONROM_BDF_1 pci_to_bdf(0x01, 0x00, 0) #define OPTIONROM_MEM_1 0xfffc0000
in src/config.h. Adjust the BDA and memory location to correspond to the rom location and the Bus/Dev/Fn for the vga card as reported by lspci (eg, the above would correspond with "01:00.0" with the option rom at the start of a 256KiB flash).

Kevin, It appears you have been pelted with this question numerious times, it may be a good idea to add it to the SeaBIOS Wiki page???

Well, it took a while, but I finally updated the wiki:
http://www.coreboot.org/SeaBIOS
Now that CBFS is in coreboot-v2, the steps are a lot easier.

I just made the romfs->cbfs change there.
