It looks like in both cases memtest86+ is loaded at address 0x00000000 which will overwrite a bunch of memory, including the coreboot tables. Looks like the memtest86+ elf binary needs to specify a load address. Stefan -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
