    I tried it yesterday on the current release of MS Virtual PC 2004
    with service pack 1 applied. You definitely need to link in the ivga
    driver (oss653a) to get a readable console. The wd driver fails to
    recognize either the emulated hard disk or the emulated cd drive.

    Using the newest wdsupp driver from MP3 and a bootstring of:

    boot: defbootstr link="ivga wd" wd.noscan wd.udma=off wd.debug=udma

    also fails, but gives some diagnostics from the detection that might
    be useful. There are no settings in the Virtual PC's BIOS regarding
    the IDE controller (which is supposed to be part of an emulated 440BX
    chipset) that are of any use in solving this problem. Interestingly, the
    emulated hardware specs for the Virtual PC specifically mention that
    the standard floppy disk controller is emulated, but make no mention of any
    sort of IDE controller, just the fact that up to 3 hard disks can be emulated
    (or actual hard disks referenced).
