IDE Disk Drive and CDROM Connector
The 3301770 provides 1 IDE channel which allows the connection to two Enhanced Integrated
Device Electronics hard disk drives or CD/DVD-ROM. The IDE controller is attached
to a PCI interface. The advanced IDE controller supports PIO mode 3, mode 4 and up to
UDMA/100 in transfer speed.
Connecting Hard Disk Drives
IDE bus devices are daisy-chained using standard a 144-pin IDE cable. Connection is made by
connecting one end of the cable to the CN30 IDE connector. The connector has a keyed pin which
prevents you from inserting the connector in a wrong direction. The read wire corresponds to pin 1
on the connector.
Plug the other end of the cable into the Enhanced IDE hard drive, with pin 1 on the cable
corresponding to pin 1 on the hard drive.
