QEMU
The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
You can easily try out coreboot using QEMU, without having to actually flash the BIOS chip on your real hardware.

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.
