1-6CHAPTER 1: INTRODUCTION

If the installation program detects Card and Socket Services in your PC, it will default to Autoset mode. Autoset mode allows your LAN driver to negotiate with Card Services for memory space and interrupts. This helps to prevent conflicts with other PC Cards that are installed in your PC; however, you will not know exactly what memory addresses and interrupts have been given to you.

Card Services requires Socket Services. The Card Services interface is usually provided with the operating system.

Advantages

■Ability to insert and remove PC Cards without PC reconfiguration and without damaging the electrical contacts.

■Automatic allocation of system resources.

■When used with your token ring software in Autoset mode, automatic configuration of your PC Card occurs.

Disadvantage

■Stay-resident program that uses system memory. The amount varies according to the type of PC Card support and the drivers used.

The file CS20TOK.EXE is a DOS Card Services 2.00 interface enabler shipped on TokenDisk diskette #2. It uses the Card Services interface to configure the socket and the PC Card. It is used when the token ring device driver is not a Card Services client driver and a Card Services environment is desired. It works with DOS Card Services 2.00 and higher.
