2.4.5. CNR (Communications Network Riser) Slot
(not available on the 366A-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 (SMBus) interfaces (used specifically to provide Plug and Play functional-
ity). The 366X-AS, 366X-AV and 366A-AV mainboards are all equipped with a single
CNR slot.
2.5.1. Floppy Disk Drive (FDD)
Connector: CN 8
Type: 34 pin block
The FDD connector can support two Floppy drives. It is located at the front of the main-
board. To connect, use the ribbon-cable that has been provided. Make sure that the red
strip is connected to PIN 1 of the connector.
2.5.2. Primary and Secondary IDE connectors
Connector: CN 9 (primary)/ CN 10 (secondary)
Type: 40 pin blocks
The 366 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.
