The MSI MS-7260 (K9N Neo), revision 1.0

This page describes how to use LinuxBIOS on the MSI MS-7260 (K9N Neo) mainboard.

The mainboard

So far we have verified that revision 1.0 of the mainboard has a socketed PLCC32 ROM chip (512KB).

If you have any other revision of the board, please contact us on the mailing list and let us know if it has a socketed (and PLCC-type) ROM chip.

Status

The respective patch is not yet committed, but it's available in the mailing list archives.

Device/functionality Status Comments
CPU Works I'm using an AMD Athlon 64 X2 Dual Core Processor 3600+, both cores work fine.
RAM Works It seems some combinations of DIMMs and RAM slots don't work. Using only one DIMM works for me.
IDE Works
SATA Untested
USB Works
On-board ethernet Works
On-board audio Works
PCI add-on cards Not working There seem to be problems with PCI add-on cards. This is being investigated.
PCI Express add-on cards Untested
Floppy Untested
Serial port (COM1) Works
Parallel port Untested
PS/2 keyboard Untested
PS/2 mouse Untested
Mainboard sensors Untested

Building LinuxBIOS

Build a LinuxBIOS payload, e.g. FILO, and copy the resulting file to /tmp/filo.elf.

$ cp payload.file /tmp/filo.elf

Checkout LinuxBIOS:

$ svn co svn://linuxbios.org/repos/trunk/LinuxBIOSv2

Build the LinuxBIOS image, containing the payload.

$ cd LinuxBIOSv2/targets
$ ./buildtarget msi/ms7260
$ cd msi/ms7260/ms7260
$ make

Write the LinuxBIOS image onto your ROM chip using flashrom:

$ flashrom -wv linuxbios.rom
WARNING: This will overwrite your current BIOS! Make sure you know what you're doing! You should have a way to revert back to the original BIOS in case anything goes wrong. It's a good idea to have a spare ROM chip which contains the original proprietary BIOS. Read the FAQ for more information. If in doubt, contact the mailing list.

Note: At the moment flashrom does not work in the MS-7260 (when booted using the original BIOS). Thus, I'm flashing the ROM chip in a different mainboard where flashrom works. However, flashrom works just fine once the MS-7260 is booted using LinuxBIOS.

TODO

  • Test the devices marked as "Untested" in the above status table.
  • Fix flashrom to also work when the board is booted using the proprietary BIOS.
  • Fix the issues with PCI add-on cards.
