Here's a nice opportunity for everyone to learn more about coreboot, a Free Software / Open Source firmware/BIOS for x86 PCs.
Ron Minnich, founder of the LinuxBIOS (now called coreboot) project, Peter Stuge of Stuge Konsult, and Stefan Reinauer of coresystems GmbH have given a presentation for the Google Tech Talks series recently. The topic was (of course) coreboot, its history, goals, features and technical details, surrounding tools and libraries such as flashrom and libpayload, as well as an automated test system for running a hardware test-suite upon every checkin in the coreboot repository.
A video of the talk, aptly named coreboot (aka LinuxBIOS): The Free/Open-Source x86 Firmware (134 MB), is available from Youtube, get it for instance via:
$ apt-get install youtube-dl $ youtube-dl http://www.youtube.com/watch?v=X72LgcMpM9k
The talk includes various demos of coreboot and various payloads you can use with coreboot. One nice example is the TINT payload, a Tetris-like game for Linux (
apt-get install tint for the curious), which has been reworked to be usable as a coreboot payload.
So, yes, you can now put Tetris in your BIOS ROM chip and play it from there (no hard drive required).
Other demos included some cluster nodes with coreboot, and a "normal" x86 desktop board booting coreboot + Linux in a very few seconds (much room left for optimizing there though, if you really want to get into fast booting).
Check out the full talk for more infos, and if you're willing to give it a try (see the list of currently supported boards), contact us on the mailing list or join the #coreboot IRC channel on Freenode.
Note: This article is part of my Testing stuff with QEMU series.
From the Debian GNU/kFreeBSD port page:
Debian GNU/kFreeBSD is a port that consists of GNU userland using the GNU C library on top of FreeBSD's kernel, coupled with the regular Debian package set.
Q: Why would anybody want to do that?
A: Why not? 
So, after we have talked about that, let's start:
apt-get install qemu
qemu-img create -f qcow2 qemu_kfreebsd_i386.img 5G
qemu -boot d -cdrom debian-20070313-kfreebsd-i386-install.iso -hda qemu_kfreebsd_i386.img
ALT-F3. Do it.
At the end you must select "No" as you're told to do, then reboot via "Exit Install". You can then shutdown QEMU.
qemu -hda qemu_kfreebsd_i386.img
apt-get update && apt-get dist-upgrade
apt-get install vim xorg icewm xterm
apt-get install kbdcontrol
Section "InputDevice" Option "Device" "/dev/psm0" Option "Protocol" "PS/2" [...] Section "Device" Driver "vesa"
Both kfrebsd-i386 and kfreebsd-amd64 seem to be reasonably stable already (and more than 70% of the whole Debian archive builds fine on these architectures, see kfreebsd-i386_stats and kfreebsd-amd64_stats). I'll quite likely install kfreebsd-amd64 on one of my boxes soonish and start using it, maybe I'll even find some time to fix/patch/port some packages...
 More elaborate answer(s) and reasons are available in the Debian wiki.
