If you ever need to clear the system CMOS memory, you can do this by moving the
jumper cap to short pins 2-3 for a few seconds. When you clear the CMOS memory,
the system must be turned off and the ATX power supply cable disconnected from the
ATX power connector on the motherboard.

Make the Internal Connections
1. Locate the floppy diskette drive connector FLOPPY. Use the ribbon cable to
connect the floppy diskette drive to the mainboard.
2. Locate the Enhanced IDE connectors CON11 (primary) and CON2 (secondary).
A single IDE cable is provided with the mainboard. Connect the cable to CON1
The cable has two connectors for IDE devices. If you connect two devices, you
must configure one device as Master, and one device as Slave. See the
documentation provided with the devices for information on this. If you need to
install more drives, obtain another IDE cable and connect one or two devices to
CON2 following the same procedure as you used with CON1.
3. Locate the bank of switch and indicator connectors J19. These connectors provide
control functions to your system case. Use the illustration below and the following
