Hi,
You need to edit SeaBIOS config.h and tell where the ROM is in final image. SeaBIOS will load it for you. I'm out on bussiness trip from next day evening. Perhaps Kevin will help with details.
I ran gpxe from coreboot-v2 with seabios. The procedure I used was:
* modify coreboot-v2 Config.lb to make room for gpxe image. I set:
option ROM_SIZE = (256 * 1024) - (62 * 1024) - (53 * 1024)
Total rom is 256KiB, 62KiB is for vga rom, and 53KiB for 10ec8167.rom (gpxe rom).
* Configure seabios to deploy both a vga rom and gpxe rom by setting in src/config.h:
#define OPTIONROM_BDF_1 0x0100 #define OPTIONROM_MEM_1 0xfffc0000 #define OPTIONROM_BDF_2 0x0048 #define OPTIONROM_MEM_2 0xfffcf800
The 0xfffc0000 corresponds with the 256KiB rom. The vga adapter is at pci 1:00.0 (hex(1<<8) == 0x100) and nic is at pci 00:09.0 (hex(9<<3) == 0x48).
* Build coreboot-v2 with seabios as payload.
* Build the coreboot rom and combine with vga rom and gpxe:
cat video.bios.bin 10ec8167.rom coreboot.rom > coreboot.final.rom
Hope this helps.
