II. FEATURES
Features of This Motherboard
The P/I-P6NP5 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 and Plug and Play to make setup of hard drives
and expansion cards virtually automatic.
II. FEATURES
(Features)
• 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
together 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.
• Internal L2 Cache Support: Supports Intel CPU's built-in 256KB/
512KB (depending on CPU) Level 2 cache so that no external SRAM
chips are needed.

4MB, 8MB, 16MB, 32MB, 64MB to form a memory size between
8MB to 256MB. Supports both Fast Page Mode (FPM), Extended
Data Output (EDO) SIMMs, and Burst Extended Data Output (BEDO).
• ISA and PCI Expansion Slots: Provides three 16-bit ISA slots, four
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 5 for an optional high-performance expansion card which
includes two functions in one easy-to-install card. (For revision
compatibility information, please refer to page 18.)
• Super Multi-I/O: Provides two high-speed UART compatible serial
ports and one parallel port with EPP and ECP capabilities. 16 bit I/O
fully decoded to meet PC97 standards. 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

Installation Steps
Before using your computer, you must follow the six steps as follows:
1. Set Jumpers on the Motherboard
2. Install DRAM 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 locations of jumpers. The jumper settings will be described
(Jumpers)
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
Pin 1
top
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 to connect pins 1&2 and to connect pins 2&3. Jumpers with
two pins will be shown as for short (On) and for open (Off). 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.

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.

5. CPU External (BUS) Frequency Selection (JP2, JP3)
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 (JP4, 5, 6, 7)
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

2. System Memory (DRAM/SDRAM & 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.
Install memory in any or all of the banks in any combination as follows:
Bank Memory Module Total Memory
Bank 0 4MB, 8MB, 16MB, 32MB, 64MB x2
SIMM Slots 1&2 72-pin FPM, EDO, BEDO SIMM
Bank 1 4MB, 8MB, 16MB, 32MB, 64MB x2
SIMM Slots 3&4 72-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. Memory setup is required
in BIOS Chipset Setup "Auto Configuration" on page 34.

P/I-P6NP5 User's Manual
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.

2. Press the memory module firmly into place starting from a 45 degree
angle making sure that all the contacts are aligned with the socket.
3. With your finger tips, rock the memory module into a vertical position
so that it clicks into place.
