| 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.
| |
| | |
| 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)
| |
