VDDRV FOR IAS
This set of programs (vddrv, vdkdrv, vdprv) is a virtual disk
driver for IAS or RSX11D which was originally written about
1977. It provides virtual data disks only (must NOT run tasks
from them), but allows encryption and MUCH access checking
of access to the virtual disks, providing secure subsystems
if this is desired. Replacing the ..BLXI or ..BLXO calls
with functions that can run with no task context will allow
this driver to load tasks too. Note vdkdrv is a version that
does not ask passwords or provide encryption, just raw virtual
disks.
