This thing has my name on it! LOL.Thanks. I'm going to try it now. I am also going to try this with the ACPI tables from the vendor BIOS. The reason ACPI doesn't quite work is because coreboot does not initialize i82371eb (PIIX4E) function 3 which controls ACPI and power management. I have submitted a patch for initial work on this; Uwe is reviewing it ATM. Make sure you do NOT define SDRAMPWR_4DIMM in Kconfig for P2B. I'll see what else I missed there in supporting boards with 3 and 4 DIMM slots. BTW are you able to fill all three DIMM slots and have all memory come up properly? You, with a 3-DIMM P2B, are the test case we have been looking for. Cheers Keith -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
