(12). IDE1 and IDE2 Connectors
This motherboard provides two IDE ports to connect up to four IDE drives at Ultra ATA/100
mode by Ultra ATA/66 ribbon cables. Each cable has 40-pin 80-conductor and three
connectors, providing two hard drives connection with motherboard. Connect the single end
(blue connector) at the longer length of ribbon cable to the IDE port on motherboard, and the
other two ends (gray and black connector) at the shorter length of the ribbon cable to the
connectors on hard drives.
If you want to connect two hard drives together through one IDE channel, you must configure
the second drive to Slave mode after the first Master drive. Please refer to the drives'
documentation for jumper settings. The first drive connected to IDE1 is usually referred to as
"Primary Master", and the second drive as "Primary Slave". The first drive connected to IDE2
is referred to as "Secondary Master" and the second drive as "Secondary Slave".
Keep away from connecting one legacy slow speed drive, like CD-ROM, together with
another hard drive on the same IDE channel; this will drop your integral system performance.
