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
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:
_____________________ | |NC|09| |08|07| |06|05| |04|03| |02|01| | |
Here's a table of corresponding pins:
Mainboard connector pin | Mainboard pin Function | Standard DE9 pin connector | Standard DE9 pin Function | Mandatory for coreboot |
---|---|---|---|---|
1 | ? | ? | ? | No |
2 | RX | 3 | TX | Yes (you could do without but it's advised to get it, to be able to use certain functions of coreboot) |
3 | TX | 2 | RX | Yes |
4 | 4 | DTR | No | |
5 | Ground | 5 | Ground | Yes |
6 | ? | ? | ? | No |
7 | 7 | RTS | No | |
8 | 8 | CTS | No | |
9 | ? | ? | ? | No |
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)
- 32bit GNU/Linux trisquel distribution tested
- 64bit GNU/Linux trisquel distribution failed to initialize the USB.
Building Coreboot
To build coreboot for this mainboard:
- checkout coreboot revision 1b1309f289d6fc9f6ec348686665d25218535030
- Configure and Build it as usual(for having graphics you need to extract your VGA BIOS ROM from your BIOS)
PCIe
See http://review.coreboot.org/#/c/2067/ (which has 2 other patch-dependencies)
SerialICE
- Selecting the ASUS M4A77TD-PRO mainboard makes the serialICE shell appear once flashed(however running the BIOS under SerialICE fails at some point).
Howto
git clone http://review.coreboot.org/p/serialice.git cd serialice make menuconfig make
cd ../ cd qemu-0.15.x sh build.sh ln -s ../SerialICE/simba/*.lua ./
Add the following to asus_m4a77td_pro.lua:
microcode_patchlevel_eax = 0x010000b7 function do_mainboard_setup() do_minimal_setup() do_default_setup() enable_hook(cpumsr_hooks, filter_amd_microcode) end
Failing
It fails like that(it inits the 2 cores and we have 1 core(qemu)):

TODO
- Add defaults for the nvram settings.
- find a clean way to merge the patch for the PCIe graphic card.
- fix the Audio CODEC(it's the same than the x60 and it works on the x60):
<DarkDefender> GNUtoo-hplaptop: I think you should be able to disable it if you look at "src/southbridge/amd/cimx/sb700/late.c" and line 266
- handle suspend to ram
- lock SMM/SMI
- make it possible to run the BIOS under serialICE
- 64bit support
