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!
Note: If a device is not supported by LinuxBIOSv2, try checking LinuxBIOSv1 for support.

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.
Devices supported in LinuxBIOSv1
Not all devices have been ported from LinuxBIOSv1 to LinuxBIOSv2, yet (check "v2?" field). If you want to work on such a port contact us on the mailing list.

1 The W83977EF works fine with the W83977TF code in LinuxBIOSv2 (the pre-RAM serial part at least).
2 Pre-RAM serial output works in LinuxBIOSv2, but the rest is not supported, yet.
