Supported Chipsets and Devices

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/
