Socket Services 1-5

When configuring two or more PC Cards, you must allocate memory and interrupt resources manually.

Socket Services

This is a BIOS-type interface that provides a way to gain access to the PC Card sockets (slots) of a PC. It identifies how many sockets your PC has and detects the insertion or removal of a PC Card while the PC 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 PC, because the driver must understand the PC's BIOS and PCMCIA controller.

The Socket Services interface enabler shipped on TokenDisk diskette #2 is TOKENRNG.EXE. It will not work with Socket Services 2.0 or higher.

The file TOKENRNG.EXE is an MSDOS Socket Services 1.01 interface enabler. It uses the Socket Services that is included in some PCs to configure the socket and PC Card. It is used on machines with DATABOOK PC Card controllers that support the Socket Services 1.01 interface and not Card Services.

Card Services

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.
