For X60
I am the maintainer for the [http://libreboot.org/ libreboot project]


Compile GNUtoo's fork of coreboot with:
You can contact me on freenode IRC, with my handle 'francis7'.
- GRUB2 payload
(previously 'fchmmr')
- native graphics (replacement for VGA option ROM / Video BIOS / VBIOS)
 
This version also removes the nonfree microcode.
 
I have tested this on an X60s 170237G.
 
GNUtoo uses this on an X60.
 
I hope to test it on more machines also.
 
 
git clone git://gitorious.org/gnutoo-for-coreboot/build-makefiles.git
 
(get the grub config, etc)
 
that is where i got the grub.cfg from.
 
rename it to coreboot.cfg and put it in the root of the grub source code directory
 
(see below)
 
note: i'm not using this. i adapted my own.
 
(at the time of writing, here is my grub.cfg, renamed to coreboot.cfg:
http://paste.debian.net/69573/
)
 
 
 
git clone git://gitorious.org/gnutoo-for-coreboot/coreboot.git
 
cd coreboot
 
git checkout 6ec9b1637b4e75de0ae4e2de258f72a7811aafbf
 
(the checkout gets gnutoo's patches to remove microcode, etc)
 
the .config (included in this post), put it in the coreboot directory.
I got it from here, which GNUtoo uploaded:
http://paste.debian.net/68794
 
Now coreboot is there, with the right config.
 
Now need to compile grub2
 
 
 
come out of coreboot:
 
cd ..
 
do that:
 
git clone git://git.savannah.gnu.org/grub.git
 
cd grub
 
./autogen.sh
 
./configure --with-platform=coreboot
 
make
 
 
 
Now we need to create a grub elf file as the payload:
 
note: in grub source root directory, make a coreboot.cfg with your grub config text inside
 
 
 
do that command:
 
./grub-mkstandalone --grub-mkimage=./grub-mkimage -O i386-coreboot -o grub2-X60.elf --modules='ahci pata ehci uhci ohci usb_keyboard usbms part_msdos xfs ext2 fat at_keyboard part_gpt usbserial_usbdebug cbfs' --install-modules='ls linux search configfile normal cbtime cbls memrw iorw minicmd lsmmap lspci halt reboot hexdump pcidump regexp setpci lsacpi chain test' --fonts= --themes= --locales= -d grub-core/ /boot/grub/grub.cfg=coreboot.cfg
 
 
 
test qemu.elf in a coreboot.rom compiled for qemu first (not covered in this guide).
 
assuming that it works, continue on...
 
 
ok,
 
just put grub2-X60.elf (it will be in the root of the grub source directory) in coreboot directory.
 
in make menuconfig, change the path to say grub2-X60.elf
 
then:
 
make
 
 
and now a coreboot.rom is in ./build/
 
 
if you are flashing this for the first time on a machine that has the factory bios, then using the
 
coreboot.rom just follow the wiki insturctions, especially with regards to the dd commands and the bucts commands
 
 
most important:
- cd build
- dd if=coreboot.rom of=top64k.bin bs=1 skip=$[$(stat -c %s coreboot.rom) - 0x10000] count=64k
- dd if=coreboot.rom bs=1 skip=$[$(stat -c %s coreboot.rom) - 0x20000] count=64k | hexdump
- dd if=top64k.bin of=coreboot.rom bs=1 seek=$[$(stat -c %s coreboot.rom) - 0x20000] count=64k conv=notrunc
 
 
flash the resulting coreboot.com like you normally would.
 
(with the dd commands you should also be able to use the flashing procedure from factory BIOS, but I
haven't tested that. yet)
 
 
see below:
 
 
 
---
 
.config (put it in root coreboot source directory) is like this:
download that text, save it as .config and put it in coreboot source directory
(you need it)
