- Summary: vlrdisk.arc, Vladimir Lanin's RAMdisk version 1.0
- Approved: dhesi@bsu-cs.UUCP

- This is VDISK, a program I have written. It is a shareware run-time
- RAMdisk, i.e. a RAMdisk that takes up no memory until you need to use
- it, and then is installed by running a program, not re-booting.

- I have seen two types of RAMdisks before: Those that are portable
- because they are device drivers, but allow their size to be changed
- only by rebooting, and those that allow their size to be changed at any
- time, but are not portable because they trap a ROM entry point that
- does disk input/output.
-
- This one seems to combine the advantages of both, with the following
- exceptions: (a) A relatively innocuous ROM routine is called to find
- the memory size of your system. (b) It takes advantage of a knowledge
- of MS-DOS's well-documented-but-not-by-Microsoft *current* memory
- allocation strategy, which is always subject to change.
-
- However, unlike IBM's VDISK, this one doesn't use extended memory, so
- if you have PC-DOS on an AT you will probably use that one instead.
-
- The author tested it only under MS-DOS 2.x. I tried it under PC-DOS
- 3.1 and it seemed to work. -- R.D.
