Hello and thank you in advance for your time.

 I recently bought a KGPE-D16 motherboard with a single AMD Opeteron
8262SE and coreboot installed. I bought from another supplier 4 memory
sticks Samsung 8GB (M393B1K70DH0-YK0) that per this thread[1] should
work with coreboot. I am able to start the assembled system and to get
serial output. According to the logs, coreboot first does the
initialisation and training of the memory and then start working on the
PCIs. At one point in the boot sequence, I get the following message:

Loaded segments
BS: BS_PAYLOAD_LOAD times (us): entry 0 run 80561 exit 0
POST: 0x7b
Jumping to boot code at 000ff06e(b7cc1000)
POST: 0xf8
CPU0: stack: 00150000 - 00151000, lowest used address 001509e0, stack

entry    = 0x000ff06e
lb_start = 0x00100000
lb_size  = 0x00116270
buffer   = 0xbfdd3000

Then it stalls for like 20-30 seconds and the booting process restarts
from the beginning. I had considered different options in order to boot
and I would like to know if someone would have any recommendations.
Right now my priority is to get the system up and working. I can worry
about installing coreboot later, but having it now is for sure a plus:
  1) Buy a new chip with the original ASUS BIOS in order to boot the
system.
  2) Externally flash the chip I have right now with a newer version of
coreboot. I probably have enough things at home to flash it, but I have
not found information from ASUS. In coreboot there is some information
but very general and not enough for my knowledge. As far as I have read
from flashrom, I should be able to flash it using a Raspberry Pi or a
BeagleBone Black, but KGPE-D16 is not marked as supported and I don't
know which model is the BIOS chip to check if it is supported.
  3) The moderboard datasheet has a section called: "Force BIOS
recovery setting", which says that in order to flash the proprietary
BIOS, it is as simple as changing a jumper an inserting an USB stick. I
would have already done it if I would not be reluctant to believe that
it is that simple.

Which are your thoughts about this ideas? Any other one that would be
simpler and would let me boot the full system?

Thank you very much,
Pablo.


NOTE: I have tried with the 4 sticks in the orange slots, the 4 sticks
in the 4 further DIMMs from the CPU (2 orange, 2 black) and those
configurations both 1.35 and 1.5V. Logs are slightly different, in the
training section, but the problem while booting remains. A USB stick
with Debian Installer has been plugged-in during since boot process
begins.
