I am using 3com's universal NDIS-over-UNDI driver.  But I am not even
getting that far...

I do not have MS-DOS 7.10, but I do have MS-DOS 6.22.  Here are the
results.

  MS-DOS + MS himem.sys:  Works

  MS-DOS + FreeDOS himem64.exe: Works for a while, but the keyboard
    tends to lock up

  FreeDOS + FreeDOS himem64.exe: As reported (instant reboot)

  FreeDOS + MS himem.sys: Very weird...  Screen goes blank, laptop
    beeps four times at one-second intervals, hard drive activity
    light comes on, machine is totally non-responsive.

I cannot use emm386.exe because it is incompatible with CWSDPMI, so I
plan to use umbpci instead.  But I am not loading it for this test;
only the XMS provider.
