This page lists hardware known to NOT work with Plan 9. Entries here should note the reason for the incompatibility and include a datestamp. Please be as specific as possible about part, model, and revision numbers, including firmware and BIOS versions when relevant. Don't mention hardware for which there is obviously no driver support; this list is intended to enumerate broken hardware that you would have expected to work ... MOTHERBOARDS * Intel D945GCLF2: Very broken ACPI implementation. Fails to boot the Plan 9 loader; seriously hosed under FreeBSD as well. (2009-12-30 lyndon@orthanc.ca) * Intel DG45ID: ACPI-only, no MP tables, so only one core will be seen. (15 Jan 2010 geoff@plan9.bell-labs.com) * Intel DG45MJ: built-in Ethernet is Realtek and doesn't PXE boot correctly. (19 Jan 2010 geoff@plan9.bell-labs.com)
