APPENDIX A

What is PC Card (PCMCIA) device driver?

A PC Card device driver contains several components: Socket services, Card services, Resource Initialization Utility and Card Installation Utility. The remaining of this section will explain the four components and list the names of the device driver for some major PC Card software vendors.

Socket Services provides the interface between a system*s BIOS and the host controller chips (such as the Intel 82365SL PCIC and the DataBook TCIC-2/N). Socket Services includes functions such as configuring a socket for an I/O or memory interface and controlling socket power voltages. The Socket Services driver operates the host controller chip of your computer.

Card Services provides the interface between the PC Card card and the Sockets Service driver. To make sure Card Services operate flawlessly regardless of the system, some PC Card device driver provide their own resource initialization utility, which will check all of the I/O ports, IRQs, and memory addresses used by the computer and report that information to Card Services.

The Card Installation Utility detects the insertion and removal of a PC Card, and determines the card type upon insertion, then the card and socket will be configured properly.

These components are loaded into the system during boot-up via the statements in the C:\CONFIG.SYS file. Along with the four components you may find other types of device drivers for various types of PC Card like SRAM card, FLASH memory card, and ATA/IDE hard drive card.
