Hi, I was hoping someone could help me out or point me in the right direction with a tyan s2912-e board not booting with coreboot,

2x 2419 opterons
16GB ECC DDR2 RAM

Onbard SAS LSI 1064e
AMD Radeon 7850 2GB

the codes on the onboard POST display (from port 80) are changing so fast that I cannot make them out however it is seems by the pattern of codes outputted that it is in a loop, are there any particular settings in the menuconfig that are required? Or have I missed something obvious?

The system flashes with flashrom no problem
I have tried booting with 1 CPU and just 1 stick of RAM, removed the PCIe GFX card. I have also built coreboot with and without the onboard VGA bios but none of this makes any difference, any help would be greatly appreciated.

I don't have personal experience with the s2912-e, so these are general debugging approaches. It could help you find a specific area that is failing. Then someone else might spot what's going on. :-)

Would it help if you inserted some busy loops at interesting points in the code? I mean something like for (i = 0; i < 1000000; i++) for (j = 0; j < 1000000; j++) for (k = 0; k < 1000000; k++) { volatile int m = 0; m++; /*to keep the compiler from optimizing the loop away*/ }

The wiki has information on where the code starts and the overall flow: http://www.coreboot.org/Developer_Manual#coreboot_Overview

From that you could place busy loops at strategic points to slow down the post codes.

Can you get a serial console log?

Ok, hope that helps.
