Socket Services
Socket Services is a BIOS-level program that controls the PCMCIA
controller chip on the ISA Bus Board, and should be the only software
to interact directly with the socket. This driver conforms to the
PCMCIA Socket Services 2.10 specification. The name of the driver is
TMB250.SYS.
TMB250.SYS is loaded in the CONFIG.SYS file.
Card Services
The Card Services driver (CTALKCS.EXE) provides a standardized set
of higher-level functions for operating all the PCMCIA sockets in the
system. It manages the communication for the client drivers including
the Super Client driver and the other drivers that manage specific cards.
The main jobs of the Card Services driver are to:
•
Manage a pool of resources to be assigned to individual cards at the
request of the card’s client driver.
•
Issue commands to Socket Services to control the PCMCIA sockets
and cards.
•
Provide a standardized interface that is available to the client drivers
and enablers supplied by card manufacturers.
Together, Card and Socket Services software identifies how many
PCMCIA sockets the computer has and assigns resources to the sockets
based on the requirements of each card. Card and Socket Services
software also detects the insertion or removal of a PC Card while the
computer is on.
Super Client Driver
A “Super Client” is a client driver that knows how to control a wide
variety of PC Cards. Super Client driver, CARDTALK.SYS, supports
the following cards:
•
SRAM memory cards
•
Flash memory cards
•
Fax/modem cards and serial cards
•
ATA rotating disk drives and solid-state devices.
