4.5 PATA Drive Installation Guidelines

The computer system boards for these products have one Parallel ATA (PATA) channel with a single connector. The channel can have up to two devices attached to it. All drives are connected to the channel using an industry-standard 80-conductor cable.

✎The industry-standard 1.44 MB diskette drive has its own separate channel and is not included as a part of the maximum four ATA drives.
