About This Guide
This manual describes Caldera DR-DOS(TM) version 7.02, a disk operating system
designed to run on Intel* Pentium, i486, 386*, 80286, 8088, 8086, (and later)
and compatible microprocessors.
Caldera DR-DOS also includes Personal NetWare(TM), a networking
component that allows you to share your computer's resources with other
users on a DOS network.
Before you start using the operating system or the network, read the
documentation from the manufacturer of your computer so that you are
reasonably familiar with the computer and how it works.
You should also read Chapter 1, ``Introduction to
DR-DOS'' and Chapter 4, ``Working with
Caldera DR-DOS,'' which describe the main features of the operating system and
explain certain concepts that you should be familiar with before you use
the operating system.
Before starting to set up your Personal NetWare network, read the
section in Chapter 18, ``Introduction to Personal
NetWare'' which describes terms and concepts related to networking and
Personal NetWare in particular.
This manual, the Caldera DR-DOS User Guide, documents all
aspects of the operating system and networking software.

Key Features in Caldera DR-DOS
This version of Caldera DR-DOS includes these key features.
DR-DOS version 7.02 is Year 2000 compliant. The DR-DOS kernel will correct the
system date even if your BIOS does not support the Year 2000.
DR-DOS now allows co-existence with Microsoft* Windows 95 and MS-DOS 7.0. The
installation program detects that Windows 95 is installed and automatically installs
the Caldera DR-DOS dual boot program LOADER.COM. When your computer is started, you can
select which operating system to use. More information about using LOADER is described in
- The Personal NetWare networking component enables you to set up a
peer-to-peer DOS network so that you can share resources between
computers running Caldera DR-DOS and MS Windows. Personal NetWare
includes a network diagnostics program.
- The INSTALL and SETUP programs are enhanced to include the new
operating systems features.
- The Task Manager has been enhanced to provide ``multitasking'' on
386 (and later) computers. This means that you can run multiple applications
- Security for your computer is enhanced, including the following
- The Stacker program allows you to create and work with Stacker
- NWCACHE is a disk caching program that makes your operating system
run faster by reducing the time it spends waiting for data from disk.
- The EMM386 memory manager is enhanced to support DPMI and multitasking. A new
parameter has been added to allow you to remove the default disabling of XMS calls
to use upper memory blocks.
- DOS Protected Mode Services (DPMS) allow DPMS-aware programs to run
in protected mode. Caldera DR-DOS DPMS-aware programs include DELWATCH,
the disk cache (NWCACHE), and the Personal NetWare server (SERVER.EXE).
- MS Windows versions of LOCK and the network commands are included.
also a Caldera DR-DOS program group for MS Windows.
- EDIT, the text editor, has a new menu interface that includes mouse
support. Also, DOSBook can now be accessed from within EDIT.
- The DOSKEY command allows you to create and work with macros.
- The new debugger, DEBUG, is compatible with other earlier DOS versions.
Although DEBUG is not documented in this manual, it is fully documented in
DOSBook, the online manual.
- FDISK has been enhanced and now has two modes of operation. The default, standard
mode has not been changed and works in the same way as previous versions. This is the
recommended way of using FDISK.
The /x switch changes to extended mode. It allows you to add and remove non-DOS
partitions. This is for advanced users only.
- NetWars is an arcade-style network game that you can play alone or
with other network users. Players can design their own ship using the shape
editor, NWDRAW.EXE, save it as a file, then load it into the Multi-Player game
from the Options menu. Online help for the shape editor is included.
