The Master or Slave status of the hard disk drive is set on the hard disk itself. Please refer to the
hard disk drive user's manual.
To connect Ultra DMA 133 and Ultra DMA 100 devices on IDE1and IDE2, an Ultra DMA 66
cable is required.
A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to
the IDE connector pin 1 before inserting the wire connector into the IDE connector.
This motherboard provides two IDE ports (IDE1 &
IDE2) to connect up to four IDE devices in Ultra
DMA 133 mode by Ultra DMA 66 ribbon cables.
Each cable has 40-pin 80-conductor and three
connectors, providing two hard drive connections
with the 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
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 device,
like CD-ROM, together with another hard disk drive on
the same IDE channel; this will decrease your integral
system performance.
