System Board 1-1
The V60N is a high-performance system board with a 64-bit
architecture. It supports the new Intel Pentium Pro CPU running at
150/166/180/200 MHz and utilizes the Peripheral Component
Interconnect (PCI) local bus architecture. The PCI local bus
maximizes the system performance by enabling high-speed
peripherals to match the speed of the microprocessor with its 120 MB
or 132 MB per second transfer rate in burst mode.
The board comes with four ISA and four PCI slots for future
expansion. The six 72-pin SIMM sockets allow you to upgrade system
memory to a maximum of 384 MB.
Onboard I/O interfaces comprise of two UART 16C550 serial ports, a
parallel port with ECP/EPP feature, and PS/2 keyboard and mouse
ports. These allow the system to support various I/O devices.

1.4 ESD Precautions
Always observe the following electrostatic discharge (ESD)
precautions before installing a system component:
1. Do not remove a component from its anti-static packaging until
you are ready to install it.
2. Wear a wrist grounding strap before handling electronic
components. Wrist grounding straps are available at most
electronic component stores.

2. Open the system according to the instructions in the housing
installation manual.
3. Follow the ESD precautions in section 1.4 before handling a
system component.
4. Remove any expansion boards or peripherals that block access
to the SIMM sockets or CPU socket.
5. See the following sections for specific instructions on the
component you wish to install.

Do not attempt the procedures described in
the following sections unless you are a
qualified service technician.
1.6 CPU Installation
The system board comes with a zero-insertion force (ZIF) CPU socket
for easy installation.
Follow these steps to install an Intel Pentium Pro CPU:
1. Locate the CPU socket on the system board and pull up the
socket lever.
2. Align pin 1 of the CPU with hole 1 of the socket. The dot on the
CPU indicates pin 1. The topmost label indicates the CPU
frequency and the cache size.
