Note
Use the primary IDE interface to connect only IDE hard disk
drives. You must connect any other type of IDE devices to the
secondary IDE interface. Never connect an IDE CD-ROM drive
to the same interface used by an IDE hard disk drive.
Before you install a drive, identify pin 1 on the drive connector
so you know where it is when you connect the drive cable. On a
hard disk drive, turn it over so you can see the circuit board, as
shown in the next illustration. Locate the side of the drive
connector containing pin 1, indicated by a 1 printed on the
connector or the board (a 2 may be printed beside the opposite
row of pins to indicate the side of the connector containing pin
1). On a CD-ROM drive, pin 1 is next to the power connector.
For hard disk drives, you may also want to make a note of the
drive parameters (such as cylinders and heads), in case the
SETUP auto-sensing feature cannot detect these parameters
when you configure the drive. The parameters may be listed on
a drive label or in the drive documentation.
