Onboard Connectors; Disk Drive Controller & I/O Port Connectors - Abit PR5 User Manual

O n b o a rd C o n n e c to rs
There are several connectors for various features on the
mainboard. If your PR5 is already installed in a system,
you can skip this section. The PR5 has onboard connec-
tors for the floppy and hard disk controllers, I/O ports,
connections from your system case and several other fea-
tures. Their locations are shown in the Configuration
Quick Reference, so they are not repeated here. This sec-
tion explains what the connectors are and how they work.
Disk Drive Controller & I/O Port Connectors
The PR5 has floppy disk drive and Enhanced IDE con-
trollers built-in. The EIDE controller is for both hard disk
drives and other devices which have an EIDE interface
such as CD-ROM drives. You connect disk drives or other
devices to the connectors on the mainboard using cables
that come with it.
The PR5 also has I/O (Input/Output) ports built-in in-
cluding serial, parallel and USB port connectors onboard.
External ports connect to the onboard connectors via the
cables attached to ports.
Drive Controller Connectors
The PR5 comes with ribbon cables to connect your sys-
tem floppy disk and IDE drives to the mainboard. The
cables are colored on one edge to show you how to ori-
ent the cable. That edge of the cable must be at the Pin 1
end of the onboard connector when connected.
The Floppy Disk Drive Controller connects to your sys-
tem floppy drive or drives with the floppy drive ribbon
cable that comes with the PR5. One end of the cable at-
taches to the FDC connector on the mainboard and the
other attaches to the floppy disk drive. There are three
connectors on the cable, one at each end and one in be-
tween, closer to one end than the other. Floppy drive A:
attaches to the end of the cable and drive B:, if you have
one, attaches to the connector in the middle. The con-
nector at the other end connects to the mainboard.
