# 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
