does support the master and slave configuration.

Note:

Although the ATI chip is an ideal way to identify the

version of the logic board, it does not control the EIDE

interface.

Conﬁguring or Connecting Master/Slave Devices

Each IDE channel can support either one or two devices. All

Power Macintosh G3's have two ATA/IDe channels. ATA/IDE

devices each contain their own integrated controllers, and so

in order to maintain order on the channel, it is necessary to

have some way of differentiating between the two devices.

This is done by giving each device a designation as either

master or slave, and then having the controller address

commands and data to either one or the other. The drive that

is the target of the command responds to it, and the other one

remains silent.
