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.

features

  • compatible with nvramtool

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

The serial port is available on the 10 pin "intel" header.

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)):
