2.4.5. CNR Slot (optional for P4XA-BV)
These slots integrate audio, modem and networking on the same card. CNR
specifications support the Audio Codec 97 (AC 97) interface, LAN interfaces, USB
interfaces and System Management Bus (SMB) interfaces (used specifically to
provide Plug and Play functionality).
2.5.1. Floppy Disk Drive (FDC)
Connector: CN 8
Type: 34 pin block
The FDD connector can support two Floppy drives. It is located at the front of the
mainboard. To connect, use the ribbon-cable that has been provided. Make sure
that the red strip is connected to PIN 1 of the connector.
2.5. Internal Connectors
2.5.2. Primary and Secondary IDE connectors
Connector: CN 9 (primary)/ CN 10 (secondary)
Type: 40 pin blocks
These three 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 slave mode in the BIOS setup. Please refer to your
hard drive manual for the appropriate jumper settings
.
