Ultra DMA 4/ATA66 Drives on the Primary Channel
AMI MegaDual ships with two 80-pin IDE cables.
Although the cable is 80-pin, the connectors are still 40-pin.
80-pin cables are required to support UDMA-4/ATA66 IDE drives.
AMIBIOS automatically detects the cable type and drive type so that it can enable the
fastest IDE mode possible.
