Overview

Overview

Chapter 1

The new 1stMainboard® AM35 is an Micro ATX sized motherboard sup-
porting the latest generation of AMD® processors at industry leading speeds.
By utilizing DDR ( Double Data Rate ) transfer rate the 100/133 MHz system
bus effectively reaches Front Side Bus speeds of 200/266 MHz. The board
provides users with an ATA133 data tra nsa ction f or hard drive s and allows up
to 2 GB memory totally by 2 PC1600/PC2100 DIMM sockets.

The AM35 is based around the high performance V-link VIA ProSavageDDR
KM266 core chip with VIA VT8233A as a South Bridge. The AGP(2X/4X)
functions supported by KM266 provides you with a photo-realistic 3D expe­rience suitable for the most robust 3D games and software environments.
AC97 Codec that embedded in VT8233A, ensures high quality sound effect.

The mainboard also comes equipped with the new NOVUS® range of innova-
tive features that assist in the installation and maintenance. The features in­clude Easy Key, which provides instant keyboard access to the BIOS for
adjustments to Clock and Default settings and LogoGenie, which allows you
to create your own customized logo to be displayed during system boot up.
The BIOS Guar di a n is a n Anti V irus utility that prevents viruse s from da mag­ing your system BIOS and rendering your system inoperative.

Expansion is provided by 1 AGP(2X/4X) and 3 PCI slots. In addition, the
1stMainboard is equipped standard I/O connections include 2 serial ports (1
by pinheader), 1 parallel port, 1 VGA port, 1 PS/2 mouse and keyboard connec­tor, 4 USB ports (2 by pinhea der), 1 IR port by pinhea der , a nd 1 medi a connec­tor (Line-In, Line-Out, Mic-In, 1 front audio, 1 game port).

check the heat sink is complete contact with die of CPU.

The poor contact will bring about over heat, it may damage your
processor.

It is strongly recommended that at lea st a 250-watt A TX power pupply
be used for this motherboard. Make sure that your ATX power sup­ply can supply at least 20 amperes on teh +5-Volt lead and 10mA
on the +5-Volt standby lead (+5VSB). Your system may become
unstable / unreliable and may experience difficulty in powering up if
your power supply is inadequate.

NOTE: CD Pro that contains patch files, onboard video/audio chip
drivers, related online help and other useful information can be
found in your mainboard package.

Please install it right after your Windows operating system installa­tion is done.Place your CD Pro in the drive, an operating menu will

appears in your monitor. Please select Auto Installation. It will auto-
matically detect which software tools (patch files, drivers) that the
mainboard needs. Press OK button to go through the whole instal­lation procedure in a very straight forward and easy way. It also
provides you with a custom way to select wanted patch files and
software drivers that for onboard chips use. The top menu of the

CD Pro lists all the functions that allowed by this board.

1). Set System Jumpers

NOTE: Users are not encouraged to change the jumper settings

not listed in this manual. Changing the jumper settings improperly
may adversely affect system performance.

Clear CMOS: CLR

The CMOS RAM is powered by the onboard button cell battery. T o clear the
R TC data: (1) T urn off your computer (2) Place the jumper ca p onto the pinpair
2-3 at least 6 seconds to clear CMOS (3) Place the jumper cap onto the pinpair
1-2 to Normal (4) Turn on your computer until CMOS checksum error appears
(5) Hold down the Delete key when boots (6) Enter the BIOS Setup to re-enter
user preferences.

3) . CPU Fan Installation

W ithout sufficient air circulation, the CPU may overheat resulting in damage
to both the CPU and the mainboard.

used incorrectly. These are not jumpers, do not place jumper caps over these
pins.

CAUTION:

1. The heatsink and fan you installed must be approved by AMD.

2. The mainboard must be placed on a solid place to avoid shaking

|||||while install the heatsink and fan on the board.

3. The heatsink must be contact with the CPU top tightly.

4. Never run the processor without the heatsink properly and firmly

attached. PERMANENT DAMAGE WILL RESUL T!

4). Install Expansion Cards

This section describes how to connect an expansion card to one of your
system expansion slots. Expansion cards are printed circuit boards that, when
connected to the mainboard, increase the capabilities of your system. For
example, expansion cards can provide video and sound capabilities. The
mainboard features one AGP(2X/4X) and three PCI bus expa nsion slots.

T o install the CPU, do the following:

1 . Lift the lever on the side of the CPU socket.

2. Handle the chip by its edges and try not to touch any of the pins.

3 . Place the CPU in the socket. The chip has two notches to correctly locate

the chip. Align two notches of the processor with the two triangular
marks on the socket. Do not force the chip. The CPU should slide easily
into the socket.

4 . Swing the lever to the down position to lock the CPU in place.

5. Install the cooling fan with heat sink on top of the installed CPU.

6 . Place the mainboard (with the CPU, its cooling fan, and heat sink) into the

system chassis and affix it with screws.

2 - 9

Installation Procedures

5. Secure the board with the mounting screw removed in Step 2. Make
sure that the card has been placed evenly and completely into the
expansion slot.

6. Replace the computer syste m cover.

7 . Setup the BIOS if necessary.

8. Install the necessary software drivers for the expansion card.

4. Push the card firmly into the slot. Push down on one end of the
expa nsion card, then the other . Use this rocking motion until the add­on card is firmly seated inside the expansion slot.

CAUTION: Make sure to unplug the power supply when adding or
removing expansion cards or other system components. Failure to
do so may cause severe damage to both the mainboard and
expansioncards.
Always observe static electricity precautions.
Please read Handling Precautions at the start of this manual.

To install an expansion card, follow the steps below:

1. Remove the chassis cover and select an empty expansion slot.

2. Remove the corresponding slot cover from the computer chassis.
Unscrew the mounting screw that secures the slot cover and pull
the slot cover out from the computer chassis. Keep the slot cover
mounting screw nearby .

3 . Holding the edge of the peripheral card, carefully align the edge

connector with the expansion slot.

VIA OnChip IDE Device

OnChip IDE Channel0

When enabled, allows you to use the onboard primary PCI IDE. If a hard
disk controller card is used, set at Disabled.
