INTRODUCTION
Introduction
Product Description
The MB935 LGA 775 Pentium
Q35 chipset that can utilize a single LGA775 processor of up to 4.0GHz
or higher and supports FSB frequency of 800/1066 Mhz/1333Mhz
200MHz (800MT/s), 266MHz (1066MT/s), and 333MHz (1333MT/s)
HCLK respectively.
The Q35 chipset is designed for use with the Core.2 processor family,
including a faster 1333 MHz system bus. The integrated GMCH
component provides the CPU interface, DDR2 interface, Hub Interface.
Four DDR2 memory sockets support DDR2 667/800 SDRAM DIMM
modules of up to 8GB in capacity.
The board is designed with six Intel 82574L PCI Express Gigabit LAN
controllers. Four Serial-II ATA connectors offer 3Gb/s data throughput
speed - faster than the most advanced parallel ATA.
Additional expansion is provided by two PCI slot if the board is used
with the IP325 backplane bridge board. Other advanced features include
four USB 2.0 ports, digital I/O, four serial ports, and watchdog timer
function. Dimensions of the board are 13.98” by 7.28”.
Remarks:
MB935 supports the Intel Core 2 Duo and Intel C ore 2 Quad processors
and Intel Celeron 400 (Conroe-L) Sequence processor.

INSTALLATIONS
Installing the CPU
The MB935 motherboard supports an LGA 775 processor socket for
Intel Core 2 Duo and Intel Core2 Quad processors, and Intel Celeron
400(Conroe-L) Sequence processor.
The LGA 775 processor socket comes with a lever to secure the
processor. Refer to the pictures below, from left to right, on how to place
the processor into the CPU socket. Please note that the cover of the
LGA775 socket must always be installed during transport to avoid
damage to the socket.
6 MB935 User’s Manual
INSTALLATIONS
ATX Power Installation
The system power is provided to the motherboard with the ATX1 and
ATX_12V power connectors. ATX1 is a 24-pin power connector and
ATX_12V is a 8-pin 12V power connector.
The 24-pin power connector can to be connected to a standard 20-pin
ATX power connector in a standard ATX power supply (Min. 400watt).
Note: The power supply 5VSB voltage must be at least 2A.
Installing the Memory
The MB935 motherboard supports four DDR2 memory sockets for a
maximum total memory of 8GB in DDR memory type. It supports
DDR2 667/800.
Basically, the system memory interface has the following features:
Supports two 64-bit wide DDR data channels
Available bandwidth up to 6.4GB/s (DDR2 800) for single-channel
mode and 12.8GB/s (DDR2 800) in dual-channel mode.
Supports 256Mb, 512Mb, 1Gb DDR2 technologies.
Supports only x8, x16, DDR2 devices with four banks
Supports only unbuffered DIMMs
Supports opportunistic refresh
Up to 32 simultaneously open pages (four per row, four rows
maximum)
Dual Channel Memory Configuration
If you want to operate the Dual Channel Technology, please note the
following explanations due to the limitation of Intel chipset
specifications.
1. Dual Channel mode will not be enabled if only one DDR II memory
module is installed.
2. To enable Dual Channel mode with two or four mem ory modules (it is
recommended to use memory modules of identical brand, size, chips,
and speed), you must install them into DIMM sockets of the same color.

BIOS SETUP
BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports Intel processors. The BIOS provides
critical low-level support for a standard device such as disk drives, serial
ports and parallel ports. It also adds virus and password protection as
well as special support for detailed fine-tuning of the chipset controlling
the entire system.
BIOS Setup
The Award BIOS provides a Setup utility program for specifying the
system configurations and settings. The BIOS ROM of the system stores
the Setup utility. When you turn on the computer, the Award BIOS is
immediately activated. Pressing the <Del> key immediately allows you
to enter the Setup utility. If you are a little bit late pressing the <Del>
key, POST (Power on Self Test) will continue with its test routines, thus
preventing you from invoking the Setup. If you still wish to enter Setup,
restart the system by pressing the ”Reset” button or simultaneously
pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by
turning the system off and back on again. The following message will
appear on the screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items, <Enter> to
select, the <PgUp> and <PgDn> keys to change entries, <F1> for help
and <Esc> to quit.
When you enter the Setup utility, the Main Menu screen will appear on
the screen. The Main Menu allows you to select from various setup
functions and exit choices.

The section below the setup items of the Main Menu displays the control
keys for this menu. At the bottom of the Main Menu just below the
control keys section, there is another section, which displays information
on the currently highlighted item in the list.
Note:
If the system cannot boot after making and saving system
changes with Setup, the Award BIOS supports an override to
the CMOS settings that resets your system to its default.
Warning:
It is strongly recommended that you avoid making any
changes to the chipset defaults. These defaults have been
carefully chosen by both Award and your system
manufacturer to provide the absolute maximum performance
and reliability. Changing the defaults could cause the system
to become unstable and crash in some cases.

BIOS SETUP
Standard CMOS Setup
“Standard CMOS Setup” choice allows you to record some basic
hardware configurations in your computer system and set the system
clock and error handling. If the motherboard is already installed in a
working system, you will not need to select this option. You will need to
run the Standard CMOS option, however, if you change your system
hardware configurations, the onboard battery fails, or the configuration
stored in the CMOS memory was lost or damaged.

CPU L3 Cache
Cache memory is additional memory that is much faster than
conventional DRAM (system memory). CPUs from 486-type on up
contain internal cache memory, and most, but not all, modern PCs have
additional (external) cache memory. When the CPU requests data, the
system transfers the requested data from the main DRAM into cache
memory, for even faster access by the CPU. By default, these items are
enabled.
Quick Power On Self Test
When enabled, this field speeds up the Power On Self Test (POST) after
the system is turned on. If it is set to Enabled, BIOS will skip some

BIOS SETUP
IDE HDD Block Mode
This field allows your hard disk controller to use the fast block mode to
transfer data to and from your hard disk drive.
OnChip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with
support for two IDE channels. Select Enabled to activate each channel
separately.
IDE Primary/Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster.
Rather than have the BIOS issue a series of commands that transfer to or
from the disk drive, PIO (Programmed Input /Output) allows the BIOS to
communicate with the controller and CPU directly.
The system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select
the best available mode.
IDE Primary/Secondary Master/Slave UDMA
These fields allow your system to improve disk I/O throughput to
33Mb/sec with the Ultra DMA/33 feature. The options are Auto and
Disabled.
Robson Support
Robson is the code name for a new Intel® platform technology that uses
non-volatile memory (Flash memory) to increase system responsiveness
and make multi-tasking faster.

Reload Global Timer Events
The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can
prevent the system from entering a power saving mode or can awaken
the system from such a mode. When an I/O device wants to gain the
attention of the operating system, it signals this by causing an IRQ to
occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service.
Notes:
HPET (High Precision Event Timer) is meant to supplement and replace
the 8254 Programmable Interval Timer (PIT) and the Real-time clock's
(RTC) periodic interrupt function. Compared to these older timer
circuits, the HPET has higher frequency (at least 10 MHz) and wider
64-bit counters (although they can be driven in 32-bit mode).

The WDT is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of
system lock-up, such as when software becomes trapped in a deadlock.
Under these sort of circumstances, the timer will count to zero and the
selected outputs will be driven. Under normal circumstance, the user
will restart the WDT at regular intervals before the timer counts to zero.
