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.
