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!
coreboot v4 is the current stable coreboot tree recommended for productive use and for porting new boards.
- If a device is not supported by coreboot v4, try checking coreboot v1 or coreboot v3 for support.
- In general it is not recommended to use coreboot v3 — this was an experimental development tree which is gradually being merged into v4.
- Also, coreboot v1 should be avoided (if v4 can be used instead for your board), as it has been unmaintained for a long time. However, it is definitely desirable to port boards from v1 to v4 whereever possible.

4 The W83977EF works fine with the W83977TF code (the pre-RAM serial part at least).
5 Pre-RAM serial output works fine, but nothing else, yet.
9 Works mostly, but currently there are some limitations as to which RAM DIMMs can be used.
12 All these Super I/O chips should be supported by the "smscsuperio" driver. Only the ASUS A8000 is tested, though. The floppy disk controller, the parallel port, the serial ports (COM1 + COM2), and the keyboard should work for all chips. More advanced stuff may need more work, though.
13 The ASUS A8000 Super I/O seems to be a rebranded SMSC DME1737.
14 Working, but not widely tested, yet. Works with single DIMM DDR2.
15 The Intel 3100/EP80579 UARTs and watchdog timer are integrated as a Super I/O-like device; only the UARTs have been tested so far.
16 Two implementations: Rev B-C supported in coreboot, Rev D-E support via AGESA
17 MCP55 and CK804 are supported, but no open documents are available from NVIDIA.
18 Partially supported, but not all features implemented.
19 Only support for serial port 1 implemented, everything else is unsupported so far due to lack of datasheet.
20 Working, but not widely tested, yet. Works with single DIMM DDR2.
21 Two Implementations: CIMX SB900 & Hudson 2 and AGESA Hudson 2/3. The AGESA implementation is for Fam15tn and newer.
22 VX900 is not merged into master. Patches to add minimal support are on gerrit http://review.coreboot.org/#/c/1228/
