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?

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.

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

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

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 IrDA connector.
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
t
model name.
Del
Warning: Please avoid of using "Load
Turbo Defaults", unless you are sure
y
our system components (CPU, DRAM,
HDD, etc.) are good enough for turbo
settin
g
.
This motherboard comes with an AD 1885 AC97 CODEC; you can find the audio drive
r
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.

Award Plug and Play BIOS Extension v1.0A
Copyright © 1998, Award Software, Inc.
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.
