Installing and Replacing Desktop Board Components 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. ✏ 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 can 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 the cable to function correctly Attach the cable end with the single connector (A), which is blue and labeled P1, to the desktop board as shown in Figure 25. Attach the cable end with the two closely spaced connectors (B), which are gray and black and are labeled P2 and P3, to the drives. If connecting only one IDE drive, be sure to connect the drive to the black connector (P3). B A OM11159 Figure 25. Connecting the IDE Cable (the D815EEA2 Board Is Shown) 47

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.
✏
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 can 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 the cable to function correctly:
•
Attach the cable end with the single connector (A), which is blue and labeled P1, to the
desktop board as shown in Figure 25.
•
Attach the cable end with the two closely spaced connectors (B), which are gray and black and
are labeled P2 and P3, to the drives.
•
If connecting only one IDE drive, be sure to connect the drive to the black connector (P3).
