Intel Desktop Boards D845HV and D845WN Product Guide

Connecting the IDE Cable

The Intel® boxed desktop board package includes two IDE cables. Both are capable of connecting two drives to the desktop board. The 40-contact cable supports the Ultra DMA-33 transfer protocol. The 40-contact, 80-conductor cable supports ATA-66 and ATA-100 transfer protocols and is backward compatible with drives using slower IDE transfer protocols. Figure 16 shows the correct installation of the cable.

NOTE

ATA-66/100 compatible cables are backward compatible with drives using slower IDE transfer protocols. If an ATA-66/100 disk drive and a disk drive using any other IDE transfer protocol are attached to the same cable, the maximum transfer rate between the drives may be reduced to that of the slowest drive.

NOTE

Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive.

For correct function of the cable:

Attach the cable end with the single connector to the board.

Attach the cable end with the two closely spaced connectors to the drives.
