Linux, by default, wont use the acpi tables unless there is an smbios table. The current coreboot targets don't support building an smbios table. So, I programmed SeaBIOS to build a dummy smbios table when it is used with coreboot. It's safe to leave all of: #define CONFIG_PIRTABLE 1 #define CONFIG_MPTABLE 1 #define CONFIG_SMBIOS 1 #define CONFIG_ACPI 1 enabled. The SMBIOS helps convince Linux to use acpi, and the other three (mptable, pirtable, acpi) are automatically disabled when in coreboot mode. -Kevin -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
