TPM Unknown
Flashrom OK Works fine when booted with BIOS and also with LinuxBIOS.

Before you begin

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). The PLCC32 BIOS chip is of type SST 49LF004B of which you need a spare programmed piece. You might reflash an empty or used one plugged into your A8N.

Enable Serial Console for debugging. It will come up at 115200,8n1 option SERIAL_CONSOLE The revisions 3000 and up work, but don't expect anything to see on the POST card. The serial Terminal will show whether LB manages with your RAM.

run targets/buildtarget then run make in the A8N-E directory. you get a 512KB image. abuild may come up with a 508KB image, which is not working.


in bash you may type svn co svn://linuxbios.org/buildrom then type "make menuconfig" but the A8NE is not supported there yet.

Known issues

  • this tutorial is not as complete as the one for Gigabyte M57-SLI, so please look there for info on building the image.
  • Currently PS/2 keyboards do not work, but USB keyboards do.
  • Single DIMM support only : the blue DIMM_B1 socket should be populated 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.
