3-4-1 Hard Disk Connector (IDE1, IDE2)
The on-board Enhanced IDE controller can support up to (4) IDE hard drives
or other ATAPI devices, such as CD-ROMs. This controller, as with all
Enhanced IDE controllers, consists of both Primary (IDE 1) and Secondary
(IDE 2) ports. Each port has an associated connector and cable, which can
support up to (2) ATAPI devices each.
All IDE devices have jumpers which allow the user to configure the device
as either “Master” or “Slave”. A Master device is one that is ALONE on the
IDE cable, whereas a Slave device is installed as a SECOND device on the
same cable. Keep in mind that the Master device will appear before the Slave
device in the CMOS Setup, as well as the Operating System software.
*Refer to the device documentation for jumper settings.
The Secondary IDE port can be used for up to (2) additional ATAPI devices.
Normally it’s recommended that you connect your first hard drive to the
Primary port, and the first CD-ROM to the Secondary.
Make sure to align the RED stripe on the ribbon cable with Pin-1 on the
mainboard IDE connector. On most hard drives and CD-ROMs, the RED
stripe should be oriented towards the power connector of the device.
When using Ultra ATA 66 IDE cable, both Master and Slave drive should be
Ultra ATA 66 drive. Do not connect CDROM to Ultra ATA 66 IDE cable,
this will reduce the efficiency.
3-4-2 Floppy Disk Connector (FDD)
The on-board floppy controller supports (2) floppy disk drives.
Make sure the RED stripe on the ribbon cable is oriented towards
Pin-1. Notice the “twist” between the sets of connectors on the
floppy cable. The floppy drive “A” position is at the END of the
cable, whereas floppy drive “B” is hooked to one of the connectors
on the other side of the twist.
