About IDE
1
IDE (Enhanced IDE/E-IDE) is one of the standards applied to the connection
between personal computers and their peripherals.
A computer motherboard provides two IDE connectors (primary and second-
ary). (Although, some motherboards provide only a primary connector.)
You may connect up to two IDE devices (hard disk, CD-ROM, or CD-R
drives) to the connectors using an IDE cable. One of the devices connected via
the IDE cable is called “master” and the other called “slave.”

CD-ROM drive, and also disconnect the audio cable from the
sound card or motherboard’s audio connector.

IDE-type.
