As someone pointed already, it's pretty likely that MS-DOS 6.22 does

mentioned above in it's CHS-based routines, then you'll be even more
limited (I think it's the case).

That is *exactly* what I've been saying - I even emailed Silicon Images
about their BIOS; they might fix it or I might have to patch it myself
to put out the right numbers.

You won't still be able to access past 8GB only with CHS.
