SeaBIOS (previously known as LegacyBIOS) is an open-source legacy BIOS implementation, which can also be used as coreboot payload.

Building
SeaBIOS
You can download the latest version of SeaBIOS through a git repository:
$ git clone git://git.linuxtogo.org/home/kevin/seabios.git seabios $ cd seabios
Alternatively, the released versions of SeaBIOS can be found at http://linuxtogo.org/~kevin/SeaBIOS/.
Edit src/config.h and set the following values:
#define CONFIG_COREBOOT 1 #define CONFIG_DEBUG_SERIAL 1 #define CONFIG_PCIBIOS 0
Then:
$ make AVOIDCOMBINE=1
The final SeaBIOS payload file is out/bios.bin.elf, which can be used with coreboot v2 or v3.
coreboot
Finally, you have to build coreboot (v3 in this example) with SeaBIOS as payload:
$ cd .. $ svn co svn://coreboot.org/repository/coreboot-v3 $ cp seabios/out/bios.bin.elf coreboot-v3/payload.elf $ cd coreboot-v3 $ make menuconfig
Now enter the Payload menu and select Payload type and then An ELF executable payload file. Now exit the menu, save your settings, and build coreboot:
$ make
The file build/coreboot.rom (or build/bios.bin) is your final coreboot v3 image, which also contains the SeaBIOS payload.
Running SeaBIOS in QEMU
For running coreboot+SeaBIOS in QEMU, you need a patched version of vgabios-cirrus.bin in your build directory first:
$ cd build $ wget http://www.coreboot.org/images/0/0d/Vgabios-cirrus.zip $ unzip Vgabios-cirrus.zip $ cd ..
You can now run SeaBIOS in QEMU:
$ qemu -L build -hda /dev/zero -serial stdio
