EIDE Hard Disk Interface

The Little Board/P5x provides an interface for up to four Integrated Device Electronics (IDE)

peripheral devices, such as hard disk drives and CD-ROM drives.

! The primary IDE interface appears at connector J12, a 40-pin, dual-row connector.

! The secondary IDE interface appears at connector J17, also a 40-pin, dual-row connector.

Table 2– 27 shows the interface signals and pin outs for the IDE interface conne ctors. Table 2– 30

shows manufacturer’s part numbers for mating connectors.

Note

For maximum reliability, keep IDE drive cables less than 18 inches

long.
