         Dear Customer,

         Thank you for buying Diskless Driver for Digital UNIX Version
         2.0. Diskless Driver for Digital UNIX is a layered product,
         and is an extension of Dataless Management Services (DMS). DMS
         is required on the server system for installation and use of
         Diskless Driver for Digital UNIX.

         In a dataless management environment, a server system maintains
         the root, /usr, and /var file systems for all client systems.
         The server maintains one copy of root for each client. The /usr
         file system is exported read only and is shared by all clients
         registered to the environment. Client systems have their own
         /var file system. All paging is done on the client's local disk.

         When used with DMS, Diskless Driver for Digital UNIX eliminates
         the need for a local disk. A Single Board Computer (SBC) or
         workstation can run Digital UNIX without a disk by booting over
         the network and paging to a server system using the Network File
         System (NFS[TM]).

         For operating system prerequistes, refer to the Diskless Driver
         for Digital UNIX Software Product Description (SPD 56.37.xx).
         A minimum of 48 MB of memory is required; Digital recommends
         a minimum of 64 MB of memory. Diskless Driver for Digital UNIX
         also requires that the following Digital UNIX software subsets
         be loaded on the system where you install Diskless Driver for
         Digital UNIX:

         o  OSFBASE-the "Base System" subset

         o  OSFCLINET-Basic Networking Services

         o  OSFNFS-NFS[R] Utilities

         To install the Diskless Driver for Digital UNIX reference pages
         (manual pages), the OSFDCMT subset, Doc Tools for Manpages, must
         be installed on the system where you install Diskless Driver for
         Digital UNIX.
