How to Perform Plug and Play I nitiation

Key with PC net-I S A I I

Application Note

TITLE: How to perform Plug and Play Initiation Key with PCnet-ISA II.

KEYWORDS: Am79C961A, PnP, plugplay, auto-config, wakeup, software, ISA.

PRODUCT: Am79C961A PCnet-ISA II Jumperless, Full Duplex Single-Chip

Ethernet Controller for ISA.

VERSION: All silicon revisions.

CROSS REF: AN012001.TXT (PCnet-ISA+)

SYNOPSIS: ISA Plug and Play (PnP) devices are naturally quiescent following

system power-on and the system reset sequence. In order for your

system software to gain control of a Plug and Play device, to

perform activities such as dynamic resource allocation by

Configuration Management or EEPROM programming by a manufacturing

utility, your software must first perform two basic operations:

you must wake up the PnP device; you must allocate system

resources to the device.

This Application Note takes you through the steps necessary to

wake up the PnP Device with the standard Plug and Plug Initiation

Key, or optionally, with the special AMD Initiation Key.

Then we'll cover basic Plug and Play Register initialization for

the PCnet-ISA II Ethernet controller.
