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 Contributions welcome!


This pages is about the port to the M4A785T-M, this mainboard is very similar to the M4A785-M, but:

  • it has DDR3 instead of DDR2

Building Coreboot

To build coreboot:

  • Apply that diff:
