2.9 IDE HARD DISK INTERFACE (J12)
The Little Board/486i provides an interface for one or two Integrated Device Electronics (IDE) hard
disk drives. IDE drives, the most popular and cost-effective type of hard drive currently available,
have a standard PC hard disk controller.
A standard IDE interface appears at connector J12, a 40-pin, dual-row connector. Table 2-15 shows
the interface signals and pin outs for the IDE interface connector. Table 2-16 shows manufacturer’s
part numbers for mating connectors.
Note
For maximum reliability, keep IDE drive cables less than
18 inches long.
