Build tutorial

the first thing to remember, is that coreboot has multiple Payloads used for the boot process (SeaBIOS, FILO, GRUB2, etc), and you must build a payload first, so that coreboot can build it into itsself.

after your payload is compiled,

$ svn co svn://coreboot.org/repos/trunk/coreboot-v2
$ cd coreboot-v2/targets
$ ./buildtarget asus/p2b-f
$ cd asus/p3b-f/p2b-f
$ make -s

The resulting coreboot.rom is your coreboot ROM image you can flash using flashrom.
