2.5.2. Primary and Secondary IDE connectors
Connector: CN 9 (primary)/ CN 10 (secondary)
Type: 40 pin blocks
The U694 mainboards all have two IDE connectors: a primary and secondary. Each IDE
connector can support two IDE drives. These mainboards can therefore support up to four
IDE devices each. If you install two hard drives, you need to configure the second drive to

mode in the BIOS setup
.
Please refer to your hard drive manual for the appropriate
jumper settings.
