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, 40-conductor 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 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 desktop board (see Figure 13, A).
•
Attach the cable end with the two closely spaced connectors to the drives (see Figure 13, B).
