Supported Chipsets and Devices

Note: If a device is not supported by coreboot v2, try checking coreboot v1 for support. Do not attempt to use coreboot v3 — this is an early development version which is not ready for production use, yet.

Devices supported in coreboot v3

coreboot v3 is an alpha-stage development version of coreboot and is not meant for production use, yet!

¹ Serial output should work for all ITE Super I/Os (but is only tested on the IT8671F and IT8712F). The rest could work, but is completely untested.
² Work in progress.
³ Serial output on serial port 1 is tested and works, the rest probably not yet (tested on FDC37M602).
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.
⁶ IDE support is available and tested. SMBus support may work, but is untested. USB support is on our TODO list.
⁷ Pre-RAM serial output works fine, everything else is untested.
⁸ Works fine mostly, but support for more obscure features (floppy, game port, MIDI, IR) might need more work.
⁹ Works mostly, but currently there are some limitations as to which RAM DIMMs can be used.
¹⁰ These southbridges should all be supported by the (experimental) new code in src/southbridge/intel/i82801xx/ now. Please test this code and use this code for all new ICH* based boards. There's still some old code for the southbridges, but that should not be used anymore.
¹¹ Sort of works, but the settings are hardcoded for the Tyan S1846. This will be fixed soonish.
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 fully tested. Works with single DIMM DDR2.

Devices supported in coreboot v1

Not all devices have been ported from coreboot v1 to coreboot v2, yet (check "v2?" field). If you want to work on such a port contact us on the mailing list.
