    I guess I could around every BIOS call ...

    Also, Alan (Cox) will say that's OK until he does APM on SMP on broken
    BIOS's :-)

    We could also just say that we no longer support those broken BIOS's ...

    No. The problem is that there are some BIOS's that contain code that (even
    though they are called in protected mode) load 0x40 into ds and expect to
    be able to reference stuff ... Causes really interesting OOPSs :-(
