The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!

Before you begin
The PLCC32 BIOS chip is of type SST 49LF004B of which you need a spare pre-programmed piece.
The ASUS A8N-SLI Deluxe, an "nforce 4 sli" board probably shares the same PCB design with more solder pads populated (please confirm), and is also out of stock mostly.
The ASUS A8NE-FM/S has initial support in the form of a patch.
Hot plugging a BIOS chip was successfully done (pull out chip with glued-on handle while running Linux), so you don't necessarily need an external EPROM programmer, just a spare working 49LF004 chip. 8 MBit SST 49LF080A was also successfully flashed and booted with legacy BIOS (two images concatenated).
- Currently PS/2 keyboards do not work, but USB keyboards do.
- Single DIMM support only.
- The MAC address is stored in flash for almost all CK804/MCP55 boards. All of these boards flashed with LB 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.
