Revision as of 18:30, 22 April 2009
You can easily try out coreboot using QEMU, without having to actually flash the BIOS chip on your real hardware.
Tutorials
- QEMU Build Tutorial — Starting a Debian GNU/Linux system via coreboot + a Linux kernel, or via coreboot + FILO.
- Booting FreeBSD using coreboot — Booting FreeBSD via coreboot + ADLO.
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 + FILO
FILO is a simple bootloader which can load (e.g.) Linux kernels from disk.
The QEMU image uses coreboot v3 (r672) and FILO (r45) with a certain configuration (for example: it's looking for /boot/grub/menu.lst on hda1).
mkdir foo cd foo wget http://www.coreboot.org/images/b/b9/Qemu_coreboot_filo.zip wget http://www.coreboot.org/images/0/0d/Vgabios-cirrus.zip unzip Qemu_coreboot_filo.zip unzip Vgabios-cirrus.zip mv qemu_coreboot_filo.bin bios.bin cd .. qemu -L foo -hda /dev/zero -serial stdio
Replace /dev/zero above with a real QEMU disk image which has a /boot/grub/menu.lst on hda1 to actually boot something.
coreboot v3 + libpayload + coreinfo
This is a small payload called coreinfo.
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
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
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
coreboot v3 + Memtest86
This is coreboot v3 (r656) and Memtest86 (3.4) with serial support enabled. The VGA display in QEMU is broken after a few seconds, this is a known issue, but we don't yet know what exactly the problem is.
mkdir foo cd foo wget http://www.coreboot.org/images/3/33/Qemu_coreboot_memtest.zip wget http://www.coreboot.org/images/0/0d/Vgabios-cirrus.zip unzip Qemu_coreboot_memtest.zip unzip Vgabios-cirrus.zip mv qemu_coreboot_memtest.bin bios.bin cd .. qemu -L foo -hda /dev/zero -serial stdio
coreboot v3 + OpenBIOS
This is coreboot v3 (r672) and OpenBIOS (r186).
mkdir foo cd foo wget http://www.coreboot.org/images/9/9d/Qemu_coreboot_openbios.zip wget http://www.coreboot.org/images/0/0d/Vgabios-cirrus.zip unzip Qemu_coreboot_openbios.zip unzip Vgabios-cirrus.zip mv qemu_coreboot_openbios.bin bios.bin cd .. qemu -L foo -hda /dev/zero -serial stdio
