- Bzzzzz. Thank you for playing. :-) Well, not to be unkind, but there
- really is a way to do this, if you use QEMM for your upper memory manager.
- QEMM includes a utility which is intended for you to be able to load the
- stuff about lastdrive, among other parameters, into upper memory, and they
- are done after boot time. QEMM includes a utility called LASTDRIV.EXE
- which will change the last drive the system knows about. I use it so that
- when I don't have my network installed, I don't chomp up as much memory,
- but when I load the network, I use LASTDRIV to allocate more drives, and
- then access all of the network drives.
