This motherboard supports AMD®Athlon and Duron Socket A series CPU and 200/266MHz EV6 bus. Be

careful of CPU orientation when you plug it into CPU socket. The following steps will guide you to finish

CPU installation:

Note: If you do not match the CPU

socket Pin 1 and CPU cut edge well,

it may damage the CPU.

You can clear CMOS to restore system default setting. To

clear the CMOS, follow the procedure below.

1. Turn off the system and unplug the AC power.

2. Remove ATX power cable from connector PWR2.

3. Locate JP14 and short pins 2-3 for a few seconds.

4. Return JP14 to its normal setting by shorting pins 1 & pin2.

5. Connect ATX power cable back to connector PWR2.

Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

MK33M / MK33M(A) provide a thermal sensor that located on the center of CPU

socket to monitoring CPU temperature. The thermal sensor will detect the CPU

temperature and send this temperature signal to hardware monitoring chip. Hence, you

can monitor the CPU temperature by BIOS setup program or hardware monitoring

utility.

Plug in the CPU fan cable to the 3-pin CPU FAN connector. If you have chassis fan, you

can also plug it on SYSTEM FAN CONN connector.

Note: Some CPU fans do not

have sensor pin, so that cannot

support fan monitoring.

Full-range Auto-Detect CPU Core Voltage

This motherboard supports CPU VID function. The CPU core voltage will be automaticall

detected and the range is from 1.1V to 1.85V.

Supported CPU Frequency

Core Frequency = CPU Bus Clock * CPU Ratio

EV6 Bus Speed = CPU Bus Clock x 2

PCI Clock = CPU Bus Clock / Clock Ratio

AGP Clock = PCI Clock x 2

Tip: If your system hangs or fails to boot because of

overclocking, simply use <Home> key to restore the default

setting (433MHz).

Warning: VIA®Apollo KM133 / KM133A chipset supports

maximum 133MHz FSB and 66MHz AGP clock, higher clock

setting may cause serious system damage.

9. Connecting ATX Power Cable

Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE

connector. The blue connector is IDE1 for clear identification. Be careful of the pin1

orientation. Wrong orientation may cause system damage.

This motherboard has two 168-pin DIMM sockets that allow you to install PC100 or

PC133 memory up to 1.0GB. The MK33M / MK33M(A) supports not only SDRAM but

also VCM and Registered DRAM.

DIMM1

DIMM2

Tip: The driving capability of new

generation chipset is limited due to the

lack of a memory buffer (to improve

erformance). This makes DRAM chip

count an important factor to take into

consideration when you install DIMMs.

Unfortunately, there is no way that the

BIOS can identify the correct chip count;

you need to calculate the chip count by

yourself. The simple rule is: By visual

inspection, use only DIMMs that are

less than 18 chips.

This feature is very similar as Wake On Modem, but it goes through local area network. To

use Wake On LAN function, you must have a network card with chipset that supports this

feature, and connect a cable from LAN card to motherboard WOL connector. The system

identification information (probably IP address) is stored on network card and because

there is a lot of traffic on the Ethernet, you need to install network management software,

such as ADM, for the checking of how to wake up the system. Note that, at least 600m

ATX standby current is required to support the LAN card for this function.

12. Connecting CD-IN / M0DEM-IN / AUX-IN Cables

13. Connecting 2nd USB Port

10. Connecting WOL (Wake On LAN) Cable

11. Connecting IrDA Connector

The IrDA connector can be configured to support wireless infrared module, with this

module and application software such as Laplink or Windows 95 Direct Cable

Connection, the user can transfer files to or from laptops, notebooks, PDA devices and

printers. This connector supports HPSIR (115.2Kbps, 2 meters) and ASK-IR (56Kbps).

Install the infrared module onto the IrDA connector and enable the infrared function

from BIOS Setup, UART mode select, make sure to have the correct orientation when

you plug in the IrDAconnector.

This motherboard supports four USB ports. Two of them are on back panel connector,

the other two are on the left-bottom area of this motherboard. With proper cable, you

can connect them to front panel.

The CD-IN connector is used to connect CD Audio

cable from CDROM or DVD drive to onboard sound.

The MODEM-IN connector is used to connect Mono

IN/MIC Out cable from internal modem card to

onboard sound circuit.

The AUX-IN connector is used to connect MPEG

Audio cable from MPEG card to onboard sound.

After you finish the setting of jumpers and connect correct cables. Power on

and enter the BIOS Setup, press <Del> during POST (Power On Self Test).

Choose "Load Setup Defaults" for recommended optimal performance.

14. Power-on and Load BIOS Setup

15. AOpen Bonus Pack CD 17. BIOS Upgrade

AOpen Easy Flash is more user-friendly than traditional flash method. The BIOS binary

file and flash routine are combined together and you simply run a single file to complete

the flash process.

1. Download new BIOS upgrade zipped file from AOpen's web site. For example,

MK33M102.ZIP.

2. Run shareware PKUNZIP (http://www.pkware.com/) which supports

miscellaneous operation systems to extract the binary BIOS file and the flash

utility. Or Winzip (http://www.winzip.com/) in Windows environment.

3. Save the unzipped file into a bootable floppy disk.

For example, MK33M102.BIN & MK33M102.EXE

4. Reboot the system to DOS mode without loading any memory handler (such as

EMM386) or device driver. It needs around 520K free memory space.

5. Execute A:> MK33M102 and the program will do the rest of it.

DO NOT turn off the power during FLASH PROCESS until you are asked to!!

6. Reboot system and press <Del> to enter BIOS Setup, Choose "Load Setup

Defaults", then “Save & Exit Setup” and finish the BIOS upgrade.

Warning: The upgrade of new BIOS will permanently replace your original BIOS

content after flashing. The original BIOS setting and Win95/Win98 PnP information

will be refreshed and you probably need to re-configure your system.

16. Installing Onboard Sound Driver

You can use the autorun menu of Bonus CD disc. Choose the utility and driver and selec

model name.

Del

Warning: Please avoid of using "Load

Turbo Defaults", unless you are sure

our system components (CPU, DRAM,

HDD, etc.) are good enough for turbo

settin

This motherboard comes with an AD 1885 AC97 CODEC; you can find the audio drive

from the Bonus Pack CD disc auto-run menu.

If you encounter any trouble to boot you system, follow the procedures

accordingly to resolve the problem.

Part Number and Serial Number

The Part Number and Serial number are printed on bar code label. You can find this

bar code label on the outside packing, on ISA/CPU slot or on component side of PCB.

For example:

Model name and BIOS version

MK33M R1.00 Jan. 11. 2001 AOpen Inc.

Award Plug and Play BIOS Extension v1.0A

Model name and BIOS version can be found on upper left corner of first boot screen

(POST screen). For example:

P/N: 91.88110.201 is part number, S/N: 91949378KN73 is serial number.

MK33M is model name of motherboard; R1.00 is BIOS version

Make sure if the jumper settings for CPU and DRAMs are correct.

Clear CMOS.

Install the VGA card. Then connect your monitor and keyboard.

The problem was probably caused

by power supply or motherboard

failure. Please contact your reselle

or local distributor for repairing.

Perhaps your VGA card or monito

is defective.

Yes

It is very possible that your keyboard

is defective.

During system rebooting, press Del to enter BIOS Setup. Choose

“Load Setup Default".

The problem should be caused by the

IDE cables or HDD itself.

Re-install Windows 95, Windows 98 or Windows NT.

Yes

Turn off the power and unplug the AC power cable, then remove all

of the addon cards and cables, including VGA, IDE, FDD, COM1,

COM2 and Printer.

Turn on the power, and check if

the power supply and CPU fan

work properly.

Start

Check if there is display.

Press Ctrl, and Alt key at the

same time, hold them and then

press Del to see if the

stem reboots.

Turn off the system and

re-connect the IDE cable.

Check if the system can

reboot successfully.
