Appendix B I Configuring Your System
Your system is designed to provide a number of standard screen,
keyboard, printer, and disk drive functions without special
instructions. By specifying device drivers, you can also enable it
to perform a wide range of non-standard functions with various
peripheral devices (including printers, modems, and monitors).
For example, you can enable it to use external drives by install-
ing the DRIVERSYS device driver.
DRIVERSYS is only one of several device drivers already writ-
ten for you and provided on your MS-DOS system diskette or
Supplemental Programs diskette.
The DEVICE command tells MS-DOS to load a particular device
driver automatically whenever you start the system. For each
driver you want to install, you need to include one DEVICE com-
mand in your CONFIG.SYS file. See Appendix C. for more infor-
mation on the device driver commands. If you have written your
own device drivers, you can include DEVICE commands for
them, also.
Example:
device=b:hdrive.5Y5
installs HDRIVE.8YS (the driver that lets you use non-standard
hard disks with your system) from the root directory of the
diskette in Drive B.
Note: Because MS-DOS installs the driver each time
you start up the system, place the driver on the cur-
rent system disk. Then, you don't have to specify (in
the DEVICE command) where to look for the driver.
