Ok thank you for all your help. I can boot and run Linux 2.6.33 now and I see all four CPU cores in /proc/cpuinfo. I compiled and added SeaBIOS as payload for coreboot and it works. I also compiled and added GPXE to the image and was able to PXE-boot. However, there are a few problems:
- The server has 4x1GB memory, but I only see 1GB. Why? What can I do? - There is something wrong with the interrupts. When the kernel is initializing the ethernet interfaces it says "Determining IP information for eth0...Disabling IRQ #19" and then hangs for a long time, finally failing. If I add "irqpoll" to the kernel parameter list the server boots, but a myrinet network card installed in the PCI-X slot is still not able to set up interrupts and thus fails to initialize. mx_driver 0000:01:01.0: can't find IRQ for PCI INT B; probably buggy MP table Board 0: Could not allocate legacy IRQ 0 mx WARN: Failed to initialize Myrinet Board at 0000:01:01.0 (-6) Perhaps the below excerp from the serial port output of coreboot is significant?
