proprietary components status

  • CPU Microcode (optional)
  • VGA option rom (optional): wihtout it you will get no graphics, Note that if you use an external graphic card, SeaBIOS will probably(depending on its configuration) load the option rom(that you don't have to touch) from the graphic card.

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: 

_____________________

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 d5c998be99709c92f200b3b08aed2ca3fee2d519
  • optionally apply the azalia patch below in the azalia section of this page.
  • select the stable revision of seabios for more anti-brick safety
  • Configure and Build it as usual(for having graphics you need to extract your VGA BIOS ROM from your BIOS)

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)
  • handle suspend to ram
  • lock SMM/SMI
  • make it possible to run the BIOS under serialICE
  • 64bit support
