Installing the Motherboard
IDE devices enclose jumpers or switches used to set the IDE device as MASTER or
SLAVE. Refer to the IDE device user’s manual. Installing two IDE devices on one
cable, ensure that one device is set to MASTER and the other device is set to SLAVE.
The documentation of your IDE device explains how to do this.
About UltraDMA
This motherboard supports UltraDMA 100/66/33. UDMA is a technology that ac-
celerates the performance of devices in the IDE channel. To maximize performance,
install IDE devices that support UDMA and use 80-pin IDE cables that support
UDMA 100/66/33.
IDE2: Secondary IDE Connector
The second drive on this controller must be set to slave mode. The configuration is
the same as IDE1.
FDD: Floppy Disk Connector
This connector supports the provided floppy drive ribbon cable. After connecting
the single end to the onboard floppy connector, connect the remaining plugs on the
other end to the floppy drives correspondingly.
Installing a Floppy Diskette Drive
The motherboard has a floppy diskette drive (FDD) interface and ships with a
diskette drive ribbon cable that supports one or two floppy diskette drives. You can
install a 5.25-inch drive and a 3.5-inch drive with various capacities. The floppy
diskette drive cable has one type of connector for a 5.25-inch drive and another type
of connector for a 3.5-inch drive.
You must orient the cable connector so that the pin 1 (color) edge of the
cable corresponds to the pin 1 of the I/O port connector.
