2.7 Primary / Secondary IDE Connectors (Two 40-pin IDE)
This mainboard supports two 40-pin IDE connectors marked as IDE1 (primary IDE channel)
and IDE2 (secondary IDE channel). Each channel supports two IDE devices, making a total of
four devices. Connect your Hard Disk (the main one if you are using more than one) to the
“Master” connector (at the end of the cable) and connect it to the IDE1 (see important note
below). If your HDD supports UltraDMA/66/100, you must use an 80-wire cable, otherwise the
HDD won’t be able to reach this speed.
If you intend to operate two IDE devices from the same channel, one device must be set to
“Master” mode, the other to “Slave” mode. A Hard Disk, CD ROM or other IDE device can
have either setting, depending on device’s jumper. Please refer to the device’s manual for
more information.
NOTE: The connectors must be attached to the IDE channels the right way round.
Make sure that the red stripe on one edge of the ribbon cable (this may be faint
and could also be a dotted line) is the nearest to PIN1 (on the left as the
motherboard is shown in the picture below).
