-
- SHSUDRVX is a CD driver/controller emulator I have found useful for
- test purposes. It emulates two 2 CD drives loaded with ISO ROMS.
-
- Drive 0 has a single text file in the root directory. This file is
- also listed in the Abstract field of the primary volume descriptor(PVD).
-
- In the root directory of Drive 1 there is a copyright file and a sub-
- directory. The copyright file is a text file and is listed in the PVD
- copyright field. The HELLO.EXE in the HELLO sub-directory is executable.
-
- SHSUDRVX is loaded from the command line before loading a re-director
- such as SHSUCDX or MSCDEX.
