    Okay. Thanks to you all for the site info. The two US sites
    refused connections, but Tiwan worked.

    I downloaded the latest, compiled May, 19, 2003. BIOS
    release 1.3.

    This converted the motherboard into a DOS-only machine.
    It would not boot Linux much beyond the LILO prompt but
    it would boot DOS off from a floppy fine.

    There was nothing in the BIOS setup to enable or disable
    hyper-threading. There was some junk about enabling
    'ultra', 'turbo' and 'fast'. If 'turbo' was enabled,
    I was able to boot Linux-2.4.20. This is the dmesg
    output. It will not boot in any other 'position'.
