Building coreboot

Note: you can use the same target as for the ASUS A8N-E board. At the time of writing there's no specific target for the ASUS A8N5X.

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

Known issues

  • The MAC address is stored in flash. All A8N5X boards flashed with coreboot probably have the same MAC address. See src/southbridge/nvidia/ck804/romstrap.inc for details.
