Connecting the IDE Cable
The Intel
®
boxed desktop board package includes two IDE cables. Either cable can connect two
drives to the desktop board. The cables supports the Ultra DMA-33 and ATA-66/100 transfer
protocols. 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:
1. Observe the precautions in "Before You Begin" on page 21.
2. Attach the cable end with the single connector to the desktop board (Figure 9, A).
3. Attach the cable end with the two closely spaced connectors to the drives (Figure 9, B).
