For X60 and X60s. (not for the T60 or T60p)

thanks go to GNUtoo, PaulePanter, patrickg, phcoder and others, for all your help so far.

Compile GNUtoo's fork of coreboot with:

- GRUB2 payload (necessary. the native graphics code requires GRUB2 as a payload)
- native graphics (free replacement for the proprietary VGA option ROM / Video BIOS / VBIOS)
- nonfree microcode removed

Note: the upstream coreboot has a Kconfig option for grub2. i didn't use that. here i compiled grub2 payload manually... (upstream coreboot isn't used. we are using gnutoo's fork)

I have tested this on an X60s 170237G.

GNUtoo uses this on an X60.

I hope to test it on more machines also.

Dependencies

This is something that I did before hand. Note: I did these on Trisquel 6

(these are used to download the latest source code for coreboot, flashrom and bucts)

$ sudo apt-get -y install subversion git

(these contain tools used for compiling source code)

$ sudo apt-get -y install build-essential

(these are required for building coreboot)

$ sudo apt-get -y install libncurses5-dev doxygen iasl gdb flex bison

(required for building flashrom)

$ sudo apt-get -y install libpci-dev pciutils zlib1g-dev libftdi-dev

(i installed these before compiling grub2. As per this guide)

$ sudo apt-get install bison libopts25 libselinux1-dev autogen m4 autoconf help2man libopts25-dev flex libfont-freetype-perl automake autotools-dev libfreetype6-dev texinfo

Getting started

$ 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 grub.custom.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 grub.custom.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: GNUtoo's grub.cfg

Now coreboot is there, with the right config.

Now need to compile grub2 before compiling coreboot.

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 the root directory of the grub source code, make a grub.custom.cfg with your grub config text inside. Do this before creating grub2-X60.elf as per the command below. Here is what I put inside my grub.custom.cfg: grub.custom.cfg

do that command (it will also use your grub.custom.cfg):

$ ./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=grub.custom.cfg

test grub2-X60.elf in a coreboot.rom compiled for qemu first (not covered in this guide).

assuming that it works, continue on...

ok,

now to build coreboot.rom. first see notes at the end about nonfree microcode .h files.

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.rom 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

.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) http://paste.debian.net/68794

nonfree microcode blobs (.h header files)

GNUtoo's patch is supposed to disable the nonfree microcode on the X60. There are still some .h files. I am deleting those and then trying to build coreboot.rom again, and testing it. As I understand it, these are microcode blobs - they are proprietary. I'm not sure if some of those .h files are for X60 and that the microcode is merely disabled or actually removed. Maybe these are for other machines too. In any case, I want to remove them.

UPDATE: a coreboot.rom is compiled after removing those (now I will test it):

UPDATE: After removing those .h files (microcode blobs) and then recompiling coreboot.rom for X60 (as above), it still worked. GRUB worked, it could boot my distro. Everything works.

Do that command to remove the .h files:

Now I will attempt once more to compile a coreboot.rom and test it.

UPDATE: coreboot.rom is compiled. now i will flash it.

UPDATE: it is flashed, and works.

Do that to remove the offending files:
