Before you begin
The Asus A8N-E is a Athlon64 Socket 939 board (nforce 4 ultra) with socketed BIOS sold around €120 (mostly out of stock in 8/2007) (used items at ebay ~ €20-35 possible). It already boots LinuxBIOS. Latest legacy BIOS is from May 2006 v.1013. Socket 939 Athlons do not have Pacifica Virtualization.
The plcc32 BIOS chip is of type SST 49LF004B of which you need a spare pre-programmed piece.
A8N-sli deluxe, an "nforce 4 sli" board probably shares the same pcb design with more solder pads populated (pls cnfirm), and is also out of stock mostly. Supporting more recent A8N boards is considered, but there is no confirmation about any one already finished. A8NE-FM/S has initial support in the source tree. Biostar NF4-A9A (socket 939) also has ITE 8712F i/o and CK804 chips as the ASUS and is still being sold around 35€.
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.
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
