Installing and Replacing Desktop Board Components Connecting the IDE Cable The two IDE cables support the Ultra DMA-33 and ATA-66/100 transfer protocols. Each of the cables can connect two drives to the desktop board. Figure 9 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: • Observe the precautions in "Before You Begin" on page 23. • Attach the cable end with the single connector to the Intel desktop board (A). • Attach the cable end with the two closely spaced connectors to the drives (B).

Installing and Replacing Desktop Board Components
Connecting the IDE Cable
The two IDE cables support the Ultra DMA-33 and ATA-66/100 transfer protocols.
Each of the
cables can connect two drives to the desktop board.
Figure 9 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:
•
Observe the precautions in “Before You Begin” on page 23.
•
Attach the cable end with the single connector to the Intel desktop board (A).
•
Attach the cable end with the two closely spaced connectors to the drives (B).
