For X60

Compile GNUtoo's fork of coreboot with:

- GRUB2 payload
- 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.

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 use this guide: http://www.coreboot.org/index.php?title=GRUB2&oldid=11812 (note to self: include a backup of this)

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:

phcoder sasy to remove memdisk.tar and rebuild grub2.elf, if you want to change something

boot from grub cli, eg: grub> linux (ahci0,1)/vmlinuz root=/dev/sda1 grub> initrd (ahci0,1)/initrd.img grub> boot (on grub command line. this can boot a kernel)

.config (put it in root coreboot source directory) is like this:
