N N o o t t e e : : Plug-and-Play operating systems like Windows 98, Windows 95
OSR2, (also known as Windows 95 Version B), will usually assign avail-
able I/O and IRQ values to the EtherFast 10/100 CardBus PC Card
automatically, making the card's installation quick and easy.
If you can't seem to find an I/O address or interrupt value to use, contact your
PC's manufacturer to determine which values are currently available for use
with the EtherFast 10/100 CardBus PC Card.
Socket and Card Services
CardBus socket and card services allow your computer to recognize a
CardBus card when it is inserted into your PC's CardBus slot. Your PC will
need some kind of services installed in order to use the EtherFast 10/100
CardBus PC Card.
Most CardBus-equipped PCs have socket and card services pre-installed by
the computer's manufacturer. If you are upgrading your PC by adding a new
CardBus slot, then you need to upgrade your services as well. You have two
choices:
• Use Built-in Services in the Driver
If your computer doesn't have services (or you don't know what kind are
installed), you may be able to use the enabler built into the driver of the
CardBus Card for DOS or NT computers. The enabler tries to automatically
get the card recognized by the laptop and enable the slot to work with the
10/100 CardBus PC Card only.
• Contact Your PC's Manufacturer
If your computer doesn't have services, and the generic services contained in
the 10/100 CardBus PC Card's driver don't seem to work with your PC, con-
tact your computer's manufacturer to find out (1) what kind of services your
computer uses, or (2) how to get compatible services if your computer doesn't
have them.
N N o o t t e e : : Plug-and-Play operating systems like Windows 95 OSR2, 98,
and 2000 have socket and card services built into the operating sys-
tem. You don't need to install them if you are using these OSes.

How to Use the 10/100 CardBus PC Card's
Enabler for DOS-Based Network Operating Systems
The software disk provided with the EtherFast 10/100 CardBus PC Card includes
generic socket and card services built into the driver that can be used to enable the
EtherFast 10/100 CardBus PC Card. The card's hardware-specific client enabler
will only enable the EtherFast 10/100 CardBus PC Card. If you want to use other
PCMCIA cards in the future, you will need to obtain additional services for those
card(s) before you'll be able to use them.
When enabler loads itself into memory, it tries to choose IRQ and I/O base
address values for the EtherFast 10/100 CardBus PC Card not already in use.
Enabler also checks to see if any other service packages are loaded. If there
are any services already present in memory, enabler will attempt to load itself
without disturbing them.
Open up your config.sys file in a text editor. Scroll through the file. Find the
line that reads (or is similar to) the following:
DEVICE=C:\EMM386.EXE
It will probably be located near the beginning of the file. You will need to add
a command to the end of the EMM386 command in order to reserve an area
of memory for the 10/100 CardBus PC Card's client enabler to use.
Add the following command to the end of the EMM386 line:
NOEMS X=D000-D3FF
so that the new EMM386 line now looks something like this (it may vary
slightly):
DEVICE=C:\EMM386.EXE NOEMS X=D000-D3FF
If there are already commands on the EMM386 line, try not to disturb them
when you add the NOEMS X=D000-D3FF
N N o o t t e e : Plug-and-Play operating systems such as
Windows 95, 98, and 2000 do not require the
use of the enabler or memory exclusion.
