Chapter 4
Using MS-DOS With the Equity LT
Your Equity LT comes with version 3.2 of MS-DOS, the
disk operating system by Microsoft? In this chapter, you’ll
learn some of the basic procedures for using MS-DOS with
your computer.
MS-DOS manages the routine work of your system, such as
keeping the computer’s memory organized, controlling screen
displays, accepting keyboard input, and directing external
communication. Your software cannot communicate with the
computer’s hardware without instructions from the operating
system. The operating system controls system input and output
and the operation of all disk drives.
Before you can use an MS-DOS application program,
MS-DOS must be running in your computer’s memory. This
means that you must first load MS-DOS so that the operating
system can accept your instructions and make the right
connections.
To communicate with the operating system, you need to
enter MS-DOS commands. How much you need to know
about the MS-DOS commands depends on how you plan to
use your Equity LT. If you plan to use it only for running
application programs, you’ll use very few MS-DOS commands.
If you plan to use advanced features or create your own
programs, you’ll want to know as much as possible about
MS-DOS.
If you plan to use your computer primarily for running
application programs, you’ll find that this chapter introduces
you to the MS-DOS features you’ll use the most. For more in-
depth information about MS-DOS, see your MS-DOS manual.
The basic procedures you must know include how to do
the following:
