CHKDRVR is a small utility, which will set the batch file
ERRORLEVEL to some value corresponding to the device driver being
tested for.
Syntax : CHKDRVR dvr
Where : 'dvr' is a letter corresponding to the following
device drivers :
E = Expanded Memory
C = CD Rom
M = Mouse
J = Joystick
K = 101 Keyboard
A = ANSI.SYS
X = Extended Memory
Defaults: All devices are tested by default, unless one or more
of the above letters is supplied as 'dvr'.
ERRORLEVELS: 0FF (255) Program Problem (call Author)
128 ANSI.SYS is installed
64 Joystick is installed
32 Extended memory driver installed
16 Expanded memory driver installed
8 101 Keyboard supported
4 Mouse driver installed
0 - 3 Number of CD Roms
** NOTE ** Although CHKDRVR can test for several device drivers
at one time we suggest you test for one at a time to ease the
batch file developement burden. IE.. its much easier to make 16
checks rather than the possible 256 tests.
USAGE: Usefull to check various system drivers

EXAMPLES:
CHKDRVR A
This will return an errorlevel of 128 if ANSI.SYS (or compatible)
driver is installed, else errorlevel is 0.
CHKDRVR C
This will return an errorlevel of 0 thru 3 for the number of CD
Roms installed, with 0 implying none.
CHKDRVR E
This will return an errorlevel of 16 if an Expanded Memory driver
is installed, other wise will return a zero.
CHKDRVR J
This will return an errorlevel of 64 if a joystick is detected.
CHKDRVR K
This will return an errorlevel of 8 if the system Bios supports
the 101 keyboard.
CHKDRVR M
This will return an errorlevel of 4 if a Mouse driver is
installed.
CHKDRVR X
This will return an errorlevel of 32 if an extended memory driver
