I  just went and looked at the sources to VDISK (DOS 2.0) and VDISK (DOS
3.0) and I have to disagree. Both of them put the disk area  immediately
after  the  driver code (the only place it is easy to put them given the
DOS rules).

Has anyone any other ideas? To reiterate, I want to put  my  RAMdisk  at
the  top  of  my 640K memory so that the fast motherboard memory is left
for applications.
