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|

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

Patch 1

Patch1 Requirements/Issues

  • the -pae kernel didn't boot my LUKS hdd(failed at cryptsetup password entering)... => using a -generic kernel worked(however that sees only 2772M in htop(I've 4GB))
  • if you remove the PCIe card, the integrated ATI card won't come up...
  • you only see the external graphic card in lspci, like with the BIOS, which seem to be the way to go...

Patch1

From ab15ce791543cb0c1a09317962fe6bdc79e4e1b3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] IRQ tables for getting the PCIe graphic card working

Thanks a lot for the help trough IRC in the #coreboot channel
  on the Freenode servers.

Patch 2

Patch2 Requirements/Issues

  • see both cards and memory regions have some issues because of that.
  • VESA works
  • -pae works
  • nouveau fails like that:

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

WARNING, This Howto is for SerialICE and not for coreboot, don't flash the resulting image unless you really know what you're doing...
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
