2.8 EIDE HARD DISK INTERFACE
The Little Board/P5i provides an interface for up to four Integrated Device Electronics (IDE) peripheral
devices, such as hard disk drives and CD-ROM drives.
A standard IDE interface appears at connector J12, a 40-pin, dual-row connector. Additional signals
needed for a third and fourth drive appear on J17. (If you only intend to connect one or two drives, you
do not need to connect a cable to J17.)
Table 2–15 shows the interface signals and pin outs for the IDE interface connector, J12. Table 2–16
shows the signals for the IDE extension connector, J17. Table 2–17 shows manufacturer’s part numbers
for mating connectors for J12 and J17.
Note
For maximum reliability, keep IDE drive cables less than 18 inches
long.
