Work in progress
Looks like we need some things that are on wikipedia mediawiki [1] but not here or default in 1.12 [2] for this to look good. I'm copying a lot of syntax from this wikipedia article [3].
Specifically this syntax is not working:
Footnote / reference syntax
<ref name="coreboot-on-dbe61c-usb">http://wiki.thincan.org/DBE61#Caveats states that "USB boot is not possible without highly experimental code."</ref>
Example: [1]
Template syntax
{{yes}}
{{no}}
{{rh}}
Example: style="background: #90ff90; color: black; vertical-align: middle; text-align: center; " class="table-yes"|Yes
Please help
Please add to this list, and speak up if you see something that you know is non-free!
Desktops
Definition
These systems at minimum should have:
- The ability to work stand-alone - no reliance on other computers being available
- Libre boot firmware (BIOS)
- No components that can not be replaced by a person with a screwdriver that require drivers with binary blobs to function
- Usually wifi adapters and graphics adapters are the issues here - you can help with this if you are a hacker with appropriate skills...
- Not make an insane amount of noise or have a form factor that is aimed at the server market

Misc Notes
BeagleBoard RevC2
- 3D graphics require a binary blob, but you can just not use 3D graphics.
- Boot loader is u-boot. ROM source isn't open, but ROM is really ROM, in the chip, not flashable from software. There is a loader between the ROM and u-boot called x-loader, but it is based on u-boot and is free software.
- x-loader is also called MLO when put on a sd-card : from the #beagle channel: "<khasim> MLO is x-loader, x-loader is strip down version of u-boot, used to get a minimal bootloader onto OMAP3's internal RAM, generally used with NAND and MMC booting as they are don't support executing in place"
- the tools for compiling and flashing x-loader are free software : "<Gnutoo> ok are the tools for compiling x-loader and flashing it free software? => <jpirko> Gnutoo: yes" and the source of some uttilities can be find here
- The Always Innovating Touch Book is basically a BeagleBoard in a (*really* :-) nice case.
- See IRC logs starting here for more...
- It's *really* tiny. The box is about the size of 2 packs of playing cards.

- Kridner observed that the board's HDMI video port is not actually HDMI-compliant. However, he said it "works great" with low-cost HDMI-to-DVI adapters and ordinary LCD flat panel displays. "The splashscreen is 1280 x 1024, but the bottleneck is on the pixel clock, which has a 75MHz limitation. So right now we can do 720p — 1280 x 720 — at 30 frames per second," he said. [5] - This is good as HDMI is usually DRM-encumbered [6].
ThinCan DBE61C-USB
Really expensive shipping.

ThinCan DBE61C-USB
TODO
Machines to evaluate when possible
- Lemote Fuloong Mini - not available outside of china to the general public as far as I know - might be possible to get if you are a hacker and contact them directly. Need someone who speaks a Chinese language to comment on price and availability within China (this info doesn't seem to be available in English).
- ThinCan DBE63 - should be available in Q2 or Q3 2009.
Routers
A lot of router run or are capable of running a GNU/Linux distribution,but most of them have non-free wifi drivers despite of having a free bootloader(which replace the bios)
- /brcm47xx HOWTO free your wrt54*/brcm47xx router : running a 100% free GNU/Linux distribution on your wrt54*/brcm47xx router router is possible...it just need to be polished
- routers with atheros wifi cards usually come with wifi driver named madwifi and that contain(need to verify if it's still the case) a blob named HAL. but Master mode may be possible with the ath5k driver + wireless-compat
Laptops
Lemote
The Lemote yeeloong is the first fully free laptop, including the Bootloader(that replaces the BIOS) and the operating system.There are no firmwares in the wifi card. A port of gnewsense is beeing developed for this laptop,and the laptop is used by Richard Stallman.
Characteristics
- MIPS 64 CPU@800MHz
- 512MB or 1GB of DDR2 RAM
- 1024x600 screen
- 160GB hard disk or 2GB SSD or 8GB SSD
Components
The components are part of a computer,such as the graphic card and can be used to choose laptop and embedded computers ,or to make or choose Desktop computer
Graphic cards
- Free Graphic cards drivers must be checked in order to see if there are some sort of microcode loaded.
Intel Cards
Most of intel card come with a free software driver but some cards like the GMA 500 are instead a Powervr which lacks free software driver for something else than framebuffer
Ati Cards
The status of the most common Ati chipset support in the free software driver can be find here
Nvidia Cards
The support for Nvidia cards in the free software driver is very experimental,status can be find here
