Introduction
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
The port is in the very early stages...(it will be ok when screen will not flickers at resolutions > 800x600)
Building the serial port adapter
You'll need to build a serial port adapter to get the coreboot logs during.
Here's a picture of the serial port connector on the mainboard:
And here's the kind of cable you will need:
And you'll need to build a cable similar to this one(on the picture the DB9 is connector is a male connector):
Here's how it looks like on the mainboard:

Adapting GNU/Linux
Before booting with coreboot, do the following:
- blacklist the snd-hda* modules (refer to the usual way to get help for the GNU/Linux distribution you want to run for doing that)
Building Coreboot
To build coreboot for this mainboard:
- checkout coreboot revision 7916f4cef62bf032af86368a9df45db833d09b79
- revert the following commit: 8660a1aa56caeb31bfaf15464285ca650638515e
