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.

• Chapter 15, ``Recovering Information,'' describes how you can recover deleted data, and how the file recovery commands work together.
• Chapter 16, ``Redirecting Information,'' explains how to redirect the input and output of information on your computer.
• Chapter 17, ``Setting Up Code Page Switching,'' explains how to set up and use code page switching on your system. The operating system allows you to change between different character sets, so that you can work with documents in different languages using a mechanism called code page switching.
• Chapter 18, ``Introduction to Personal NetWare,'' introduces the terms and concepts you need to be familiar with before setting up or using the Caldera DR-DOS network component.
• Chapter 19, ``Planning Your Network,'' is intended for the person who is responsible for setting up the network and describes the issues you should consider before starting to set up the network.
• Chapter 20, ``Setting Up the Network,'' describes how to set up the network and how to change the network setup whenever necessary.
• Chapter 21, ``Using the Network,'' describes the operations you can perform as a user of the network.
• Chapter 22, ``Optimizing and Maintaining the Network,'' describes operations that you should perform occasionally to ensure that the network is operating as efficiently as possible.
• Chapter 23, ``NET Commands,'' describes how to use the Personal NetWare NET commands at the operating system prompt to perform user and administration tasks on the network.
• Chapter 24, ``Using Network Diagnostics,'' describes how to use the Network Diagnostics program, which allows you to monitor the operation of Personal NetWare in your workgroup.
• Chapter 25, ``Configuring Your Computer for Desktop SNMP Services,'' explains the procedures for configuring the workstation services.
• Chapter 26, ``Running IPX and SPX Applications in a Task-Switching Environment,'' describes how to use the NetWare(R) task switching files that provide the data buffers needed to support IPX(TM) and SPX requests made from applications running in a DOS session.
• Appendix A, ``Troubleshooting,'' describes problems you may experience using the operating system and, where possible, their solutions. This appendix also explains error messages displayed when the system either fails to boot or crashes while it is running. For explanations of other error messages, refer to DOSBook.
• Appendix B, ``Preparing the Hard Disk'' summarizes how to use FDISK to prepare the hard disk, if the hardware dealer has not done this already, before installing the operating system.
• Appendix C, ``NetWare DOS Requester,'' describes the DOS client software that provides the interface between DOS and the network.
• Appendix D, ``Code Pages,'' lists the character sets of the code pages supported by the operating system.
• The Glossary lists terms and their definitions, as used in this manual.

• 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 DOSBook.
• 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 simultaneously.
• Security for your computer is enhanced, including the following features:
  • A ``one-time login'' allows you to log in to your computer and any Novell(R) network to which you are connected.
  • A ``screen saver'' allows you to lock your computer against unauthorized use without logging out.
• The Stacker program allows you to create and work with Stacker compressed drives.
• 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. There is 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.
