For sure vdisk.lst and vdisk.sys is on the second ("supplemental") diskette
sent by IBM as PC-DOS 3.1.  vdisk.lst is a listing file, so some work needs
to be done if you want to modify and reassemble the source.  But vdisk.sys
works fine, as stated above, though it must be an IBM thing rather than a
Microsoft thing.
