Quoting original post: EIP=fff0 EFL=0002 [---] CPL=0 II=0 A20=1 SMM=0 HLT=0 ES = 9300 CS =f000 9b00 That is the reset vector, i.e. something going seriously wrong on the very first instruction executed. rom image being garbage or something like that. Check your build environment. Broken toolchain? Disk full? The new crash is at some completely different place, so coreboot at least starts executing. Try this ... qemu -bios coreboot.rom \ -chardev stdio,id=log \ -device isa-debugcon,iobase=0x402,chardev=log ... to see the coreboot log (assuming coreboot comes far enough to actually produce log output). cheers, Gerd -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
