4.8.1 Primary / Secondary IDE Connectors (IDE0 / IDE1)
This motherboard provides four independent Ultra ATA/66 IDE channels, which
doubles the ATA/33 burst data transfer rate to 66 MB/s and are 100 percent backward
compatible with all existing ATA / ATAPI devices. These connectors also support
ZIP and LS-120 devices.
The ATA/66 requires a special 40-pin, 80-conductor cable that reduces noise bleed-
over and improves signal integrity by providing 40 additional ground lines between
each of the standard 40-pin ATA (IDE) signal lines and ground lines. Although a new
40-pin, 80-conductor cable is required for Ultra ATA/66, the chipset pin connector
remains the same at 40.

A legacy ATA (IDE) drive can coexist with an Ultra ATA/66 drive. However, for the
Ultra ATA/66 device to attain Ultra DMA 4 mode, an Ultra ATA/66 capable cable is
required.
