IDE

A pair of standard parallel ATA (IDE) channels are provided. The two chanels are presented as a 44 way laptop style pin header (PL29) and a 44 way socket on the underside of the unit (PL28). The underside socket is suitable for direct mounting of a standard 2.5inch laptop hard drive.

The two channels are buffered and isolated form the rest of the systems busses but do share a single buffer for the data signals, this may cause issues with some ATA devices (notably cheap CF cards) which do not properly qualify their data bus usage with their respective separate read and write strobes.
