Shuttle SN25P

This is just a work-in-progress status page...

The port is not functional yet.

I started my work on Shuttle SN25P motherboard [[1]] by looking at Supported_Motherboards page, chose a supported one that has similar hardware (ASUS_A8N-E_Build_Tutorial)

Uwe told me where to start modifiying the code to adapt it to motherboard specificities, and more importantly, where to find the information to put in place.

Hardware:

• AMD K8 Northbridge
• NVIDIA CK804 Southbridge
• ITE IT8712F Super I/O
• AMD Opteron 165 dual core Socket 939

Additionally:

• RD1 BIOS Savior with XXXX Flash chips for work and backup

OK:

• flashrom from linux over legacy BIOS
• Serial console
• Coreboot runs
• Load & run payload (tested OK: filo & memtest86)
• Filo loads a kernel & jump to its entry point
• Kernel start to boot and hang at the console handling code, right after "Detected 1800.234 MHz processor."

NOK:

• VGA (not in coreboot, not in filo, not in memtest86, not in linux kernel)
• Keyboard (idem)
• Etherboot (onboard nvidia ethernet adapter not properly configured by coreboot)
• Network

Files:

• Config.lb - OK
• mptable.c - should be OK, linux kernel apic=debug output is identical as with legacy BIOS
• irq_tables.c - should be OK too
• get_bus_conf.c - WIP, still buggy

Information gathering:

• getpir
• mptable
• superiotool
• lspci -tnvv
• lspci -vvvxx
• setpci -s 0:0:1.0 7c.L
• setpci -s 0:0:1.0 80.L
• setpci -s 0:0:1.0 84.L

TODO: - Make it boot to Xorg - ACPI - Etherboot for BCM - TG3 PCIe 1x addon card - LAB ? (may need bigger flash) - Other payloads
