 Although the ATI chip is an ideal way to identify the 

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

interface.

 

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.
