This HOWTO explains how to use coreboot on the M4A785T-M board. The main difference between the '''[https://www.asus.com/Motherboards/M4A785M/ ASUS M4A785-M]''' and the '''[https://www.asus.com/Motherboards/M4A785TM/ M4A785T-M]''' is the support of DDR3 on the latter.

=== RAM issue ===
* 32bit untested.
* 64bit was tested and works with 2G of RAM.
** When using more than 4G of RAM, I can't boot GNU/Linux anymore:
***USB devices not seen, some errors -71), with mem=4000M, that works ok again.
***SATA devices are also not seen, and with mem=4000M, it also works ok again.

== Introduction ==
== proprietary components status ==
This pages is about the port to the M4A785T-M, this mainboard is very similar to the M4A785-M, but:
* Optional CPU Microcode
* it has DDR3 instead of DDR2
* Optional VGA option rom: wihtout it you will get no graphics, Note that if you use an external graphic card, SeaBIOS load the option rom with its default configuration from the graphic card.
 
** You can also patch SeaBIOS to put the option rom in memory without running it. That way the linux driver will then find the option rom bytecodes and tables to initialize that GPU.
== Building the serial port adapter ==
  From 83bbd30b3ef76fc346c417fa08ba716b4e2fb179 Mon Sep 17 00:00:00 2001
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:<br />
[[Image:ASUS_M4A785T-M_serial_connector_witout_serial_adapter.jpeg]]<br />
And here's the kind of cable you will need:<br />
[[Image:ASUS_M4A785T-M_serial_connector_with_serial_adapter.jpeg]]<br />
And you'll need to build a cable similar to this one(on the picture the DB9 is connector is a male connector):<br />
[[Image:ASUS_M4A785T-M_serial_cable.jpeg]]<br />
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)
* 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...

Add mem=4000M to the kennel cmdline, that can be done by adding the following to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and regenerating grub.cfg:
* see both cards and memory regions have some issues because of that.
  mem=4096M
* VESA works
* -pae works

Latest revision as of 18:59, 13 October 2016

This HOWTO explains how to use coreboot on the M4A785T-M board. The main difference between the ASUS M4A785-M and the M4A785T-M is the support of DDR3 on the latter.

Status

RAM issue

  • 32bit untested.
  • 64bit was tested and works with 2G of RAM.
    • When using more than 4G of RAM, I can't boot GNU/Linux anymore:
      • USB devices not seen, some errors -71), with mem=4000M, that works ok again.
      • SATA devices are also not seen, and with mem=4000M, it also works ok again.

  • Optional CPU Microcode
  • Optional VGA option rom: wihtout it you will get no graphics, Note that if you use an external graphic card, SeaBIOS load the option rom with its default configuration from the graphic card.
    • You can also patch SeaBIOS to put the option rom in memory without running it. That way the linux driver will then find the option rom bytecodes and tables to initialize that GPU.

Building the serial port adapter

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

Adapting GNU/Linux

Add mem=4000M to the kennel cmdline, that can be done by adding the following to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and regenerating grub.cfg:

mem=4096M

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)Test audio
  • Fix RAM layout to prevent issues with more than 4G of RAM
  • lock SMM/SMI if it's not already

  • Native GPU init for ATI and Nvidia GPUs

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)):
