You can easily try out coreboot using QEMU, without having to actually flash the BIOS chip on your real hardware.

Tutorials

Ready-made QEMU images

We'll soon provide various downloadable QEMU images you can use to try out coreboot.

You need a patched version of vgabios-cirrus.zip for these images to work fine, the version in QEMU's CVS repository does not yet work. The image from Debian's QEMU package (/usr/share/qemu/vgabios-cirrus.bin) is already patched and works, too.

coreboot v3 + coreinfo

coreinfo NVRAM dump.
$ mkdir foo
$ cd foo
$ wget http://www.coreboot.org/images/0/06/Qemu_coreboot_coreinfo.zip
$ wget http://www.coreboot.org/images/0/0d/Vgabios-cirrus.zip
$ unzip Qemu_coreboot_coreinfo.zip
$ unzip Vgabios-cirrus.zip
$ mv qemu_coreboot_coreinfo.bin bios.bin
$ cd ..
$ qemu -L foo -hda /dev/zero -serial stdio

coreboot v3 + invaders

GRUB invaders as payload.
$ mkdir foo
$ cd foo
$ wget http://www.coreboot.org/images/c/c8/Qemu_coreboot_invaders.zip
$ wget http://www.coreboot.org/images/0/0d/Vgabios-cirrus.zip
$ unzip Qemu_coreboot_invaders.zip
$ unzip Vgabios-cirrus.zip
$ mv qemu_coreboot_invaders.bin bios.bin
$ cd ..
$ qemu -L foo -hda /dev/zero -serial stdio

coreboot v3 + libpayload + tint

tint as payload.

This is coreboot v3 (r656), libpayload (r3225), and tint 0.03b patched to be built against libpayload.

$ mkdir foo
$ cd foo
$ wget http://www.coreboot.org/images/6/62/Qemu_libpayload_tint.zip
$ wget http://www.coreboot.org/images/0/0d/Vgabios-cirrus.zip
$ unzip Qemu_libpayload_tint.zip
$ unzip Vgabios-cirrus.zip
$ mv qemu_libpayload_tint.bin bios.bin
$ cd ..
$ qemu -L foo -hda /dev/zero -serial stdio
