Ronald G. Minnich 5e19eee460 This is a snapshot as the availability of the systems for this
project is now uncertain, and I can't invest the remaining time
needed to get it done. 

Status is that memory is still not quite configured correctly. It is close
but here are DRAM Row Boundary registers. 
Here is coreboot
60: 10 10 20 20 20 20 20 20 00 00 00 00 00 00 00 00
This is close. But: 
60: 10 10 10 10 20 20 30 30 00 00 00 00 00 00 00 00
is the real hardware. So we are somehow missing those last slots. I think it's 
because the SPD connections and the chip connections differ, some dumping
of RAM registers differ. But it's very close. 

This is under serialice. Once we get to this point we get stuck here: 
Copying coreboot to RAM.
Copying coreboot to RAM.
Copying coreboot to RAM.

Forever. 

Here is the total config for 0:0.0 from coreboot:

I want to commit this because even if I get no further, someone else might. 
Note that for serialice you need the following temporary patch as well:

README

-------------------------------------------------------------------------------
coreboot README
-------------------------------------------------------------------------------

coreboot is a Free Software project aimed at replacing the proprietary
BIOS you can find in most of today's computers.

It performs just a little bit of hardware initialization and then executes
one of many possible payloads, e.g. a Linux kernel or a bootloader.


Payloads
--------

After the basic initialization of the hardware has been performed, any
desired "payload" can be started by coreboot.

See http://www.coreboot.org/Payloads for a list of supported payloads.


Supported Hardware
------------------

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

 * http://www.coreboot.org/Supported_Motherboards
 * http://www.coreboot.org/Supported_Chipsets_and_Devices


Build Requirements
------------------

 * gcc / g++
 * make
 * python
 * perl

Optional:

 * doxygen (for generating/viewing documentation)
 * iasl (for targets with ACPI support)
 * gdb (for better debugging facilities on some targets)


Building coreboot
-----------------

Please consult http://www.coreboot.org/Documentation for details.


Testing coreboot Without Modifying Your Hardware
-------------------------------------------------

If you want to test coreboot without any risks before you really decide
to use it on your hardware, you can use the QEMU system emulator to run
coreboot virtually in QEMU.

Please see http://www.coreboot.org/QEMU for details.


Website and Mailing List
------------------------

Further details on the project, a FAQ, many HOWTOs, news, development
guidelines and more can be found on the coreboot website:

  http://www.coreboot.org

You can contact us directly on the coreboot mailing list:
