Setting the Jumpers
Jumpers are used on this mainboard to select
various settings and features. A 2-pin jumper
has two settings: Open and Short (or Closed).
The jumper is closed by placing the Jumper
Cap across the two pins, thereby connecting
them. 3-pin jumpers can be set to pins 1-2 or 2-
3 connected. Pin-1 is labeled on the circuit
board.
Setting the CPU Clock Selection Jumper (JP5)
After installing the CPU, you must set the
clock selection jumper to match the frequency
of the CPU. Find the Jumper Block labeled
JP5 on the mainboard. Set the jumper
according to the table at right for the CPU
frequency you are using.
The CPU Clock corresponds to the number
marked on the CPU. The Bus Clock when
multiplied with the Ratio gives the CPU
Clock.
üü For a dual CPU system: It is recommended that you use two identical CPUs in your
system. If your CPUs have different speed requirements, you must set the CPU Clock
Selection Jumper Block to the lower frequency.
•If you are uncertain about the speed requirements of your particular CPU, you should
obtain Technical Documentation from the manufacturer. Such information is available
via the Intel WWW site.

IDE Hard Drives and CD-ROMs
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 and Secondary 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.
