ASUS P5Q

This page describes how to run coreboot on the ASUS P5Q desktop board.

TODO

The following things are working in this coreboot port:

  • PCI slots
  • PCI-e slots
  • Onboard Ethernet
  • USB
  • Onboard sound card
  • PS/2 keyboard
  • All 4 DIMM slots
  • S3 suspend and resume
  • Red SATA ports

The following things are still missing from this coreboot port:

  • PS/2 mouse support
  • PATA aka IDE (because of buggy IDE controller)
  • Fan control (will be working on 100% power)
  • TPM module (support not implemented)

The following things are untested on this coreboot port:

  • S/PDIF
  • CD Audio In
  • Floppy disk drive
  • FireWire: PCI device shows up and driver loads, no further test
