NDiS B862 and NDiS B842 motherboard.
Before You Begin
▪ Ensure you have a stable, clean working environment. Dust and dirt can
get into components and cause a malfunction. Use containers to keep
small components separated.
▪ Adequate lighting and proper tools can prevent you from accidentally
damaging the internal components. Most of the procedures that follow
require only a few simple tools, including the following:
– A Philips screwdriver
– A flat-tipped screwdriver
– A set of jewelers screwdrivers
– A grounding strap
– An anti-static pad
▪ Using your fingers can disconnect most of the connections. It is
recommended that you do not use needle-nosed pliers to disconnect
connections as these can damage the soft metal or plastic parts of the
connectors.
▪ Before working on internal components, make sure that the power is off.
Ground yourself before touching any internal components, by touching
a metal object. Static electricity can damage many of the electronic
components. Humid environments tend to have less static electricity than
dry environments. A grounding strap is warranted whenever danger of
static electricity exists.
Precautions
Computer components and electronic circuit boards can be damaged by
discharges of static electricity. Working on computers that are still connected
to a power supply can be extremely dangerous.
Follow the guidelines below to avoid damage to your computer or yourself:
▪ Always disconnect the unit from the power outlet whenever you are
working inside the case.
▪ If possible, wear a grounded wrist strap when you are working inside the
computer case. Alternatively, discharge any static electricity by touching
the bare metal chassis of the unit case, or the bare metal body of any
other grounded appliance.
▪ Hold electronic circuit boards by the edges only. Do not touch the
components on the board unless it is necessary to do so. Don’t flex or
stress the circuit board.
▪ Leave all components inside the static-proof packaging that they shipped
with until they are ready for installation.
▪ Use correct screws and do not over tighten screws.
Locations of the Jumpers and Connectors for NDiS B842
The figure below is the main board used in the NDiS B842. It shows the locations of the jumpers and connectors. Both NDiS B862 and NDiS B842 share the
same connectors except that NDiS B862 features 6 HDMIs while NDiS B842 features four HDMIs.
A jumper is the simplest kind of electric switch. It consists of two metal
pins and a cap. When setting the jumpers, ensure that the jumper caps are
placed on the correct pins. When the jumper cap is placed on both pins, the
jumper is short. If you remove the jumper cap, or place the jumper cap on
just one pin, the jumper is open.
Refer to the illustrations below for examples of what the 2-pin and 3-pin
jumpers look like when they are short (on) and open (off).
5. Insert the CPU into the socket until it is seated in place. The CPU will fit
in only one orientation and can easily be inserted without exerting any
force. Use a screwdriver to turn the screw to its locked position.
CAUTION!CAUTION!
Do not force the CPU into the socket. Forcing the CPU into the
socket may bend the pins and damage the CPU.
This chapter describes how to use the BIOS setup program for the NDiS B862
and NDiS B842. The BIOS screens provided in this chapter are for reference
only and may change if the BIOS is updated in the future.

About BIOS Setup
The BIOS (Basic Input and Output System) Setup program is a menu driven
utility that enables you to make changes to the system configuration and
tailor your system to suit your individual work needs. It is a ROM-based
configuration utility that displays the system’s configuration status and
provides you with a tool to set system parameters.
These parameters are stored in non-volatile battery-backed-up CMOS RAM that
saves this information even when the power is turned off. When the system is
turned back on, the system is configured with the values found in CMOS.
With easy-to-use pull down menus, you can configure such items as:
▪ Hard drives, diskette drives, and peripherals
▪ Video display type and display options
▪ Password protection from unauthorized use
▪ Power management features
The settings made in the setup program affect how the computer performs.
It is important, therefore, first to try to understand all the setup options, and
second, to make settings appropriate for the way you use the computer.
When to Configure the BIOS
▪ This program should be executed under the following conditions:
▪ When changing the system configuration
▪ When a configuration error is detected by the system and you are
prompted to make changes to the setup program
▪ When resetting the system clock
▪ When redefining the communication ports to prevent any conflicts
▪ When making changes to the Power Management configuration
▪ When changing the password or making other changes to the security
setup
Normally, CMOS setup is needed when the system hardware is not consistent
with the information contained in the CMOS RAM, whenever the CMOS
RAM has lost power, or the system features need to be changed.
Most of the configuration settings are either predefined according to
the Load Optimal Defaults settings which are stored in the BIOS or are
automatically detected and configured without requiring any actions. There
are a few settings that you may need to change depending on your system
configuration.
Entering Setup
When the system is powered on, the BIOS will enter the Power-On Self
Test (POST) routines. These routines perform various diagnostic checks; if an
error is encountered, the error will be reported in one of two different ways:
▪ If the error occurs before the display device is initialized, a series of beeps
will be transmitted.
▪ If the error occurs after the display device is initialized, the screen will
display the error message.
Powering on the computer and immediately pressing <Del> allows you to
enter Setup.
