But I'm not sure how widespread bios/openfirmare combo roms are used (have been used) in practice. If guests can't deal with it (and try to run a x86 emulator on the bios image instead) it might not be the best plan to go that route. > just not the QEMU > vgabios due to not emulating i386 specific opcodes that gcc puts in real > mode code What does sam460ex use? Some x86emu fork? If so upgrading might help. Xorg uses x86emu too and older versions have problems with the gcc-generated real mode code too. cheers, Gerd
