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.

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.
