Appendix C / Installable Device Drivers
ANSI.SYS
(For Extended Screen and Keyboard Control)
ANSI.SYS is a loadable driver that provides programmers with
many extended screen and keyboard features. With it installed,
you can change graphics functions, move the cursor, and
reassign the meaning of any key on the keyboard by issuing spe-
cial character sequences from within your program. These
sequences are valid only when issued through MS-DOS function
calls 1, 2, 6, and 9. For more information, see your MS-DOS
Pro-
grammer's Reference Manual.
Include the following command in your CONFIG.SYS file to
install the ANSI.SYS driver:
DEVICE
=

(For Additional Disk Drives)
DRIVERSYS is an installable device driver that enables your
system to support more than two floppy disk drives and more
than two hard disk drives.
In addition, DRIVERSYS lets you assign more than one logical
drive letter to a single drive.
To install the DRIVERSYS driver, include a DEVICE command
in your CONFIG.SYS file, using this format:
DEVICE
=
DRIVER.SYS
/D:n [lC] [/F:n] [lH:n] [IN] [lS:n]
[/T:n]

/D:n specifies the physical drive number in the range 0 to 255.
Floppy drives are numbered starting at 0, and hard disk drives
are numbered starting at hexadecimal 80. For example, if you
i
have a computer with two floppy disk drives, the drives are num-
~
bered 0 and 1. If you add another floppy disk drive, its physical
drive number is hexadecimal 02. (The first external floppy drive .- ,
is always hexadecimal 02.)
~
If you have one floppy disk drive and one hard disk drive, the
floppy disk drive is hexadecimal 00, and the hard disk drive is
i '
hexadecimal 80.
