Right after reset it wouldn't be a NOP, but this seems to be a lot later. (Real mode f000:0000 after reset maps to physical ffff0000.) > CBFS: Found 'fallback/romstage' @0x80 size 0x3ba0 in mcache @0x00014e2c > WARN - MOVS to ROM at RIP ffffdc2f RCX ee8 ff200300->ff200300 I guess this is in 32-bit mode. coreboot leaves real mode quickly. Anyway, memory mapped sounds correct for QEMU. :) //Peter _______________________________________________ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-le...@coreboot.org
