Hello! I tested intel uefi payload instead of seabios in coreboot minnowboard max . It failed with "Failed to find the required acpi table ". If I use seabios payload ,the bios runs ok! I followed "http://www.elinux.org/Minnowboard:MinnowMaxCoreboot" to build coreboot. I used "https://firmware.intel.com/develop/" 2014-WW26-UEFI.coreboot.Payload.zip to builed uefi in coreboot. The whole terminal log is : POST: 0x4a POST: 0x4b POST: 0x4c POST: 0x4d POST: 0x4e POST: 0x4f POST: 0x39 POST: 0x80 POST: 0x70 POST: 0x71 POST: 0x72 POST: 0x24 POST: 0x25 POST: 0x24 POST: 0x25 POST: 0x55 POST: 0x24 POST: 0x25 POST: 0x55 POST: 0x55 POST: 0x73 APIC: 00 missing read_resources PCI: 00:00.0 missing set_resources POST: 0x74 POST: 0x75 POST: 0x75 POST: 0x93 POST: 0x9b POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 POST: 0x75 Warning: PCI Device 2 does not have an IRQ entry, skipping it POST: 0x75 POST: 0x75 POST: 0x76 POST: 0x77 find_current_mrc_cache_local: No valid fast boot cache found.
