IDE Connector
The board provides a set of parallel IDE connector (Pitch: 2.0mm), which shares an
IDE bus with the CF card connector; therefore, please pay attention to the following
issues when installing the IDE devices:
Ø
If the CF card connector has been occupied with CF storage card, the IDE
connector can only connect with one IDE device; one is Master device and the
other is Slave device, which can be set via JP1. The relevant jumper is provided
on the hard disk to set it to Master device or slave device;
Ø
If the CF card connector is not occupied, the IDE connector can connect with
two IDE devices. The way of connection is to connect the Master device to the
end of the cable while connect the Slave device to the middle of the cable; when
using an Ultra 66/100 hard disk, 80pin appropriative flat cable shall be adopted.
