One point enabler is supplied for this PC Card:
POINTTR.EXE
For computers with Intel 32365SL PCMCIA controller chip sets or any
controller that is designed to be compatible. These include the IBM
ThinkPad, Toshiba 4500 and later, and many other makes.

Notes:
1. When using the point connectivity enabler, it is vitally important that you make
certain that the system resources used by the PC Card are different from and
do not conflict with the system resources and any other PC Cards installed in
your computer.

2. Windows NT currently uses a point enabler called PCMCIA.SYS, which
currently ships with Windows NT.

Disadvantages
v
You must specify the slot; the point enabler will enable only that slot. Therefore,
the PC Card must always be in a specific slot.

In some computers, the slot may not be switched off when the computer is in
suspend mode, so the PC Card will continue to consume power.

Socket Services
This is a BIOS-type interface that provides a way to gain access to the PC Card
sockets (slots) of a computer. It identifies how many sockets your computer has and
detects the insertion or removal of a PC Card while the computer is switched on. It
has an interface to Card Services. Socket Services is part of the PCMCIA
Specification.

The Socket Services device driver is usually provided by the manufacturer of the
computer, because the driver must understand the computer’s BIOS and PCMCIA

This is a software management interface that allows system resources (such as

memory, interrupts, slots, and I/O ports) to be allocated automatically when Socket
Services has detected that a PC Card has been inserted.
Client drivers call Card Services to allocate and de-allocate system resources.
When Socket Services detects an insertion or removal of a PC Card, it sends
notification to Card Services. Card Services then notifies its registered client drivers,
such as IBMTOKCS.OS2, that they should allocate or de-allocate resources.
