ASUS A8N-E, rev. 2.00

This HOWTO explains how to use coreboot on the ASUS A8N-E board.

Works fine, only smaller issues remain to be fixed. A list of known issues is available.


Device/functionality Status Comments
CPU works OK Tested: AMD Athlon(tm) 64 Processor 3000+ and 3200+.
L1 cache enabled OK CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line)
L2 cache enabled OK CPU: L2 Cache: 512K (64 bytes/line)
L3 cache enabled N/A
Multiple CPU support N/A
Multi-core support Untested
Hardware virtualization N/A
DDR OK Tested with one DIMM in slot DIMM_B1 (see manual). Since r3614 it's also possible to use a single DIMM in slot DIMM_B2.
Dual channel support Untested
ECC support Untested The board supports ECC according to the manual.
On-board Hardware
On-board IDE 3.5" OK Tested: Primary IDE (master and slave) and secondary IDE (master and slave).
On-board IDE 2.5" N/A
On-board SATA OK
On-board SCSI N/A
On-board USB OK Tested: USB keyboard (on each of the 10 possible USB ports).
On-board VGA N/A
On-board Ethernet OK
On-board Audio WIP This is being worked on.
On-board Modem N/A
On-board FireWire N/A
On-board Smartcard reader N/A
On-board CompactFlash N/A
On-board PCMCIA N/A
On-board Wifi N/A
On-board Bluetooth N/A
On-board SD card reader N/A
Add-on slots/cards
ISA add-on cards N/A
Audio/Modem-Riser (AMR/CNR) cards N/A
PCI add-on cards OK Tested: PCI VGA card in all three PCI slots.
Mini-PCI add-on cards N/A
Mini-PCI-Express add-on cards Unknown
PCI-X add-on cards N/A
AGP graphics cards N/A
PCI Express x1 add-on cards OK Both PCIe x1 slots works fine (tested with a network card).
PCI Express x2 add-on cards N/A
PCI Express x4 add-on cards Untested
PCI Express x8 add-on cards N/A
PCI Express x16 add-on cards WIP Doesn't seem to work, yet (?)
PCI Express x32 add-on cards N/A
HTX add-on cards N/A
Legacy / Super I/O
Floppy WIP
Serial port 1 (COM1) OK
Serial port 2 (COM2) N/A
Parallel port OK Tested: modprobe ppdev, further tests were not performed.
PS/2 keyboard WIP
PS/2 mouse WIP
Game port WIP
Infrared N/A
PC speaker OK
DiskOnChip N/A
Trackpoint N/A
Touchpad N/A
Fn Hotkeys N/A
Fingerprint Reader N/A
Docking VGA N/A
Docking LAN N/A
Docking USB N/A
Docking Audio N/A
Docking Displayport N/A
Thinklight N/A
Webcam N/A
Sensors / fan control OK Tested: sensors reports K8 core temp. (kernel module k8temp) and various other values from the IT8712F Super I/O (kernel module it87).
Hardware watchdog N/A
SMBus Unknown
CAN bus N/A
CPU frequency scaling No Needs (at least partial) ACPI support.
Other powersaving features N/A
ACPI No There's no ACPI implementation for this board.
Reboot OK
Poweroff No
Suspend Unknown
Nonstandard LEDs OK There's a green LED on the board which is enabled when the board is powered-on. Works out of the box, no special coreboot support required.
High precision event timers (HPET) OK The hardware supports it, but you currently need the hpet=force Linux kernel parameter. Reduces the number of wakeups in powertop drastically.
Random number generator (RNG) N/A
Wake on modem ring Untested
Wake on LAN N/A The on-board ethernet device doesn't seem to support WOL (also not mentioned in the manual).
Wake on keyboard Untested
Wake on mouse Untested
TPM Unknown
Flashrom OK Works fine when booted with BIOS and also with coreboot.

Building coreboot

See the Build HOWTO for information on how to build coreboot for this board.

Known issues

  • The MAC address is stored in flash for almost all CK804/MCP55 boards. All of these boards flashed with coreboot probably have the same MAC address. See src/southbridge/nvidia/ck804/romstrap.inc and src/southbridge/nvidia/mcp55/romstrap.inc for details. On some of these boards, the MAC address is stored in a separate EEPROM, but you can't count on that.
