Connecting the IDE Cable
The Intel
®
boxed server board package includes a 40-contact, 80-conductor IDE cable. This cable is
capable of connecting two drives to the server board. The cable supports Ultra ATA/100/66 and
Ultra ATA/100 transfer protocols and is backward-compatible with drives using slower IDE
transfer protocols.
✏
NOTE
ATA-66/100 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.
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 end of the cable that has a single connector (A) to the server board as shown in
Figure 18. The connector at this end of the cable is black and is labeled PRI IDE.
• Attach the end of the cable that has two closely spaced connectors (B) to the drive(s). The
connectors at this end of the cable are gray and black and are labeled P2 and P3.
• If connecting only one IDE drive, connect the drive to the gray connector (P3).
