Quick Installation
We know that many experienced people prefer to read as
little of the documentation as possible. If this sounds like
you, here’s the short form to get up and running quickly.
Installing the Helios
1. Make backup copies of your installation and configu-
ration diskettes.
2. Ground yourself to prevent damaging static dis-
charge by using an anti-static wrist or ankle strap, or
touch a safely grounded metal object.
3. Remove the Helios from its packaging.
4. Configurethesystemboard’sjumpersettings,ifneces-
sary (refer to Jumper Settings in Chapter 2).
5. Install the CPU and the system memory. Be sure to
attach the Retention Mechanism as described in
Chapter 3.
6. Install the system board in the chassis and make all
necessary case connections.
7. Install any ISA, PCI and/or AGP add-on peripherals
(refer to Chapter 2 for the location of the slots).
8. Connect any optional devices.
9. Configurethe CPU speed. The CPU speed is selected
through the BIOS. First you must close jumper W12
(refer to Jumper and Connector Settings in Chapter
2).
10. Turnon your system. When the system is powered up
itwillgo intoSetupautomatically.
11. The first selection on the Main screen will be CPU
Speed. Select the correct speed.

AdjusttheBIOSsettingstomatchyourconfiguration.If
installinganIDEdrive,selecttheIDEdeviceyouwishto
configure. Press ENTER with Type selected and the
BIOS will automatically configure the drive for you
(refer to Chapter 4).
13. Make any desired setting configurations in the other
menus (refer to Chapter 4). When finished, press F10
(Save and Exit) to save your settings.
14. You will see a message indicating that the CPU speed
setting has been saved.
15. PowerdownyoursystemandremovethejumperoffW12

Configuring the Helios
AlthoughtheHeliossystemboardispackagedinmaterials
that are designed to protect it from physical damage and
staticelectricity,it isimportanttousecarewhileunpack-
ing the board and setting it up.
Static Electricity
The Helios is shipped from the factory in an anti-static
bag. To reduce the possibility of damage from static
discharge, it is important to neutralize any static charges
your body may have accumulated before handling the
board.
The best way to do this is to ground yourself using a
special anti-static wrist or ankle strap. If you do not have
an anti-static strap available, touch both of your hands
to a safely grounded object, such as the power supply or
chassis of a computer that is connected to the power
socket. After you have grounded yourself, ground the
Helios board via one of the solder pads that surround its
mounting holes. When you remove the Helios from its
packaging, place it on top of the anti-static bag, and
carefully inspect the board for damage which might have
occurred during shipment.
Environment Considerations
Make sure the finished computer system is in an area
withgood ventilation. Thesystemshould notbein direct
sunlight, near heaters, or exposed to moisture, dust, or
dirt.

Jumper Settings
ThissectionprovidesjumpersettingsfortheHeliossystemboardthatmay
or may not need to be changed. Other configurations can be changed
throughtheBIOSSetup,suchastheCPUspeed.NOTE:Fordetailsonhow
to configure the CPU speed, see “Setting the CPU Speed” in Chapter 4.
Table 2-1 lists the settings for the BIOS Configuration Setup. To select
the CPU speed in the BIOS, you must close jumper W12. (Refer to
Chapter 4 for details on setting the CPU speed).
Table 2-2 lists the settings to clear the CMOS. With your computer's
power off, close pins 2-3, wait ten seconds and place the jumper back on
pins 1-2. (The jumper must be placed back on pins 1-2 for the system to
function properly.) NOTE: This will reset all BIOS default settings. Any
changes you have made will be lost.

J20 becomes a non-bus-mastering slot, regardless of whether the onboard
audio is enabled or disabled. Bus-mastering PCI cards (i.e., most LAN
cards and SCSI host adapters) will not work when inserted into slot J20.
They can, however, be used in slots J16-J19. Non-bus-mastering devices,
like most graphics cards, can be plugged into slots J16-J20.
