Plug and Play Glossary


Card
A physical card, also called an adapter, board, or node, that controls one or more Plug and Play ``devices''.

Device
A functional hardware subset resident on a Plug and Play card. Multiple devices, such as CD-ROM and joystick controllers, may reside on a single card.

Resources
One of the following hardware parameters that can or must be set for each configured device:

DMA
direct memory access channel

IRQ
interrupt vector

I/O address
input/output address through which this device communicates

Mem address
memory address for this device

Each resource can be set to either a value, to NONE (meaning that no value is required), or to OFF (meaning that the device is currently disabled).

For detailed descriptions of these parameters, see ``Configuration parameters''.


Resource configuration names
A set of resource values which the card manufacturer has defined. Each set of values is defined as one of the following:

Current
existing device configuration

Good
preferred configuration (highest priority)

Acceptable
lower priority configuration that is still valid

Sub-optimal
configuration that will function but should only be used if other good or acceptable configurations are not available or cause conflicts

A given device can have multiple instances of Good, Acceptable, and Sub-optimal settings.
