The 
C> 
prompt that appears when you load MS-DOS from the
hard disk tells you that drive C, your hard disk, is the current
drive (also called the default drive). The current drive is the one
that MS-DOS uses for all commands unless you specify a
different drive. For example, if the current drive is drive C and
you type the name of a program, MS-DOS searches drive C for
the program.
If you want to run a program or find a data file on a different
drive, you must specify the name of that drive. You can do this
either by logging onto that drive (making it the current drive)
or by including the drive letter with the filename.
To log onto another drive, type the name of the drive followed
by a colon. Then press Enter. For example, if the current drive
is C and you want to log onto drive A, type 
A: 
and press Enter.
Your screen now displays the 
A> 
prompt, showing that you are
operating from drive A. Drive A continues to be the current
drive until you log onto a different drive or turn off or reset your
computer.
To access a program or file on another drive without first
logging onto that drive, specify the drive identifier (the name of
the drive followed by a colon) along with the filename. For
example, if you are logged onto drive C and you want to run a
program called WP that is stored on drive A, type 
WP 
and
press Enter. MS-DOS runs the program on drive A but remains
logged onto drive C.
Note
You can reverse the drive identifiers for the internal 3 
and the external 5 
 diskette drives by setting DIP
switch SW2-2 to OFF. See “Setting the DIP Switches,” in
Appendix A.
