Super Client Drivers
Many notebook PC vendors are providing customers with
super client drivers that can enable many different PC
Cards. PC-DOS 6.1 includes one called PCMSCD.EXE, for
example.
They are best used for modems and other PC Cards that
do not have a Card Services client driver of their own. If
you use a super client driver, try to disable support for the
PC Card and use the 3Com client driver. 3Com drivers
have been written to take advantage of Card Services.
Look at the documentation for your super client driver to
find out whether you can disable token ring support.
Card Services Enabler
If you want to use a token ring device driver that does
not have built-in Card Services support on a system that
uses Card Services, CS20TOK.EXE is supplied. This
program is a Card Services Enabler that uses Card and
Socket Services to configure the 3C389 PC Card. As with
other enablers, you must specify the resources desired
for the PC Card, and they must agree with the settings of
the token ring device driver for the system to work
correctly.
Card and Socket Services Versus Point Enablers
In principle, Card and Socket Services is the better
method of connection because it allows you to insert or
remove PC Cards from any slot as you want, even while
the PC is switched on (hot-swapping) and it automatically
allocates resources like memory, I/O ports, interrupt levels,
and slots.
Point Enablers, two of which are provided with the
PC Card, are popular because they remove themselves
from memory after having been loaded—as opposed to
the 30-40 KB needed for Card and Socket Services.
