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?
Send the complete boot log as an attachment and see if anyone can spot the reason.
- 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"
Did you modify mptable.c and irq_tables.c for your board? The IRQ routing is probably different than what the s2881 has. You can run getpir and look in /proc/interrupts and lspci when you boot with the factory BIOS.
Perhaps the below excerp from the serial port output of coreboot is significant?
POST: 0x66 Allocating resources... Reading resources... APIC: 00 missing read_resources APIC: 01 missing read_resources APIC: 02 missing read_resources APIC: 03 missing read_resources
That's normal. The APICs don't have any PCI resources.
Thanks, Myles
