II. FEATURES
Features of the ASUS Motherboard
The ASUS P/I-XP6NP5 is carefully designed for the demanding PC user who wants
a great many features in a small package. This motherboard:
•Easy Installation: Is equipped with BIOS that supports auto detection of hard
drives, PS/2 mouse, and Plug and Play devices to make setup of hard drives,
expansion cards, and other devices virtually automatic.
•Multi-Speed Support: Supports one 150-200MHz Pentium Pro CPU on a
ZIF Socket 8.
•Intel Chipset: Features Intel's 440FX PCIset with I/O subsystems.
•Error Checking and Correcting (ECC): Using Intel's 440FX PCIset to-
gether with parity DRAM modules can detect multi-bit memory
errors and correct 1-bit memory errors.
•Desktop Management Interface (DMI): Supports DMI through BIOS which
allows hardware to communicate within a standard protocol creating a higher
level of compatibility . (Requires DMI-enabled components.) (See section V)
(depending on CPU) Level 2 cache so that no external SRAM chips are needed.
•ATX Power Connector: Has a single easy-to-install connector for 3.3V, 5V,
12V, and a new soft-power control.
•Versatile DRAM Memory Support: Supports four 72-pin SIMMs of 4MB,
8MB, 16MB, 32MB, 64MB to form a memory size between 8MB to 256MB.
Supports both Fast Page Mode (FPM), Extended Data Output (EDO), and Burst
Extended Data Output (BEDO) SIMM’s.
•ISA and PCI Expansion Slots: Provides three 16-bit ISA slots, three 32-bit
PCI slots, and one PCI/MediaBus 2.0 which allows the use of either a standard
PCI card or the ASUS MediaBus Card.
•ASUS MediaBus Rev 2.0: Features an expansion slot extension shared with
PCI Slot 4 for an optional high-performance expansion card which includes
two functions in one easy-to-install card.
•Super Multi-I/O: Provides two high-speed UART compatible serial ports
and one parallel port with EPP and ECP capabilities. UART2 can also be
directed from COM2 to the Infrared Module for wireless connections. Two
floppy drives of either 5.25" or 3.5" (1.44MB or 2.88MB) are also supported
without an external card. The Japanese "Floppy 3 mode" (3.5" 1.2MB)
floppy standard is also supported.
•Ready-to-Use Connectors: Is equipped with onboard Parallel (Printer) Port,
Serial Ports (COM1&2), PS/2 Mouse, and PS/2 Keyboard connectors without
the need for extra cables and brackets.

Installation Steps
Before using your computer, you must complete the following six steps:
1.Set Jumpers on the Motherboard
2.Install DRAM (and SRAM) Memory Modules
3.Install the Central Processing Unit (CPU)
4.Install Expansion Cards
5.Connect Ribbon Cables, Cabinet Wires, and Power Supply
6.Setup the BIOS Software
1. Jumpers
Several hardware settings are made through the use of jumper caps to connect jumper
pins (JP) on the motherboard. See "Map of the Motherboard" on page 4 for loca-

(Jumpers)
tions of jumpers. The jumper settings will be described numerically such as [----],
[1-2], [2-3] for no connection, connect pins 1&2, and connect pins 2&3 respectively. Pin 1 for our motherboards is always on top
holding the motherboard with the keyboard connector away from yourself. A "1" is
written besides pin 1 on jumpers with three pins. The jumpers will also be shown
graphically such as
Jumpers with two pins will be shown as
For manufacturing simplicity, the jumpers may be sharing pins from other groups.
Use the diagrams in this manual instead of following the pin layout on the board.
Settings with two jumper numbers require that both jumpers be moved together . To
connect the pins, simply place a plastic jumper cap over the two pins as diagramed.
WARNING: Computer motheboards and components contain very delicate
Integrated Circuit (IC) chips. To protect the motherboard and other components against damage from static electricity, you should follow some precautions whenever you work on your computer.
1.Unplug your computer when working on the inside.
2.Hold components by the edges and try not to touch the IC chips, leads, or
circuitry .
3.Use a grounded wrist strap before handling computer components.
4.Place components on a grounded antistatic pad or on the bag that came
with the component whenever the components are separated from the system.

3.Real Time Clock (RTC) RAM (JP16)
This clears the user-entered information stored in the CMOS RAM of the Real
Time Clock such as hard disk information and passwords. To clear the RTC
data: (1) Turn off the PC, (2) Short this jumper, (3) Power on the PC, (4) Turn
off the PC, (5) Remove this jumper, (6) Power on the PC, (7) Hold down
<Delete> during bootup and enter BIOS setup to re-enter user preferences.
The Real T ime Clock RAM is powered by the onboard button cell battery. You
can test the battery’s current by removing this jumper and attaching a current
meter to each pin. WARNING: You must unplug the power cord to your
power supply to ensure that there is no power to your motherboard. The
RTC RAM containing BIOS setup information will be cleared by this action. You must enter BIOS to “Load Setup Defaults” and r e-enter any user
information after removing and reapplying this jumper.

5.CPU External Clock (BUS) Frequency Selection (JP8, JP9)
These jumpers tells the clock generator what frequency to send to the CPU.
These allow the selection of the CPU’ s External frequency (or BUS Clock). The
BUS Clock times the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed).
6.CPU to BUS Frequency Ratio (JP10, JP11, JP12, JP13)
These jumpers set the frequency ratio between the Internal frequency of the
CPU and the External frequency (called the BUS Clock) within the CPU. These
must be set together with the above jumpers CPU External Clock (BUS)Frequency Selection.

Set the jumpers by the Internal speed of the Intel CPU as follows:
Pentium Pro Processors may require different voltages. Current processors
(marked "Pentium Pro") support VID and will automatically adjust the voltage
regulator so that no jumper settings are needed (leave these jumpers open in this
case). Older processors without VID support require manual voltage ID setting.
Use [S] for Short and [O] or Open.
If the ATX power supply is equipped with +3.3V, then choose ATX, some supply . If the ATX power supply is not equipped with +3.3V, then choose Onboar dRegulator. Move all three jumpers together as illustrated.

2. System Memory (DRAM & SRAM)
This motherboard supports four 72-pin SIMMs (Single Inline Memory Modules) of
4MB, 8MB, 16MB, 32MB, 64MB to form a memory size between 8MB to 256MB.
The DRAM can be either 60ns or 70ns Fast Page Mode (Asymmetric or Symmetric), Extended Data Output (EDO), or Burst Extended Data Output (BEDO). SIMMs
must be installed in pairs so that each bank contains two of the same size memory
modules. To support ECC, you must use true (opposed to phantom parity generated by TTL chips) 36-bit parity-type SIMM (e.g. 8 chips + 4 parity chips) in pairs
for all modules. Mixing 32-bit non-parity SIMM (e.g. 8 chips) and 36-bit SIMM
(e.g. 12 chips) will work minus the ECC feature.
III. INSTALLATION
(Memory)
Install memory in any or all of the banks in any combination as follows:
BankMemory ModuleTotal Memory
Bank 04MB, 8MB, 16MB, 32MB, 64MBx2
SIMM Slots 1&272-pin FPM, EDO, BEDO SIMM
Bank 14MB, 8MB, 16MB, 32MB, 64MBx2
SIMM Slots 3&472-pin FPM, EDO, BEDO SIMM
Total System Memory=
IMPORTANT: Each bank must have the same size and type (FPM, EDO,
BEDO) of memory installed in pairs.
IMPORTANT: Memory setup is required using “Auto Configuration" in
Chipset Features Setup of the BIOS SOFTWARE.
IMPORTANT: Each bank must have the same size memory installed in pairs.
Do not use memory modules with more than 24 chips per module. Modules
with more than 24 chips exceed the design specifications of the memory subsystem and will be unstable.

DRAM Memory Installation Procedures:
1.The SIMM memory modules will only fit in one orientation as shown because
of a "Plastic Safety Tab" on one end of the SIMM sockets which requires the
"Notched End" of the SIMM memory modules.
