Thank you, i will try it and report back asap.

I like using the memtest that comes with my distro, so I add this simple patch to SeaBIOS when I want to test RAM. It makes memtest ignore the Coreboot tables. I think you'll want to be sure that RAM is working. Thanks, Myles

From src/mainboard/tyan/s2895/dsdt.asl: /* There is no _PRT Here because I don't know what to * put in it. Since the 8131 has its own APIC, it * isn't wired to other IRQs. */ I don't know what it's supposed to look like, and I don't have any PCI-X hardware. This would be a good place to start if you'd like to investigate. You could compare it to the DSDT that came with your factory BIOS. Thanks, Myles
Hello, i will dump the dsdt table from 1.06 bios from linux /proc/acpi, disassemble it with iasl, and then compare it with the one provided in coreboot source code. I will then let you know what i found.
