CNR (Communication and Network Riser) is a riser card specification to replace the AMR (Audio / Modem Riser) that supports V.90 analog modem, multi-channel audio, and phone-line based networking. Owing to CPU computing power getting stronger, the digital processing job can be implemented in main chipset and share CPU power. The analogy conversion (CODEC) circuit requires a different and separate circuit design, which is put on CNR card. This motherboard implements sound CODEC on board, but reserve CNR slot for the option of modem function. Note that you can still use PCI modem card.

ACPI Suspend to Hard Drive is basically controlled by Windows operation system. It saves your current work (system status, memory and screen image) into hard disk, and then the system can be totally power off. Next time, when power is on, you can resume your original work directly from hard disk within few seconds without go through the Windows booting process and run your application again. If your memory is 64MB, normally, you need to reserve at least 64MB HDD space to save your memory image.
When go into Suspend: System Image & Status

Save into

Hard Disk
When power-on next time: System Image & Status

Restore within seconds

System Requirement
1. 2. AOZVHDD.EXE 1.30b or later. Delete config.sys and autoexec.bat.
Fresh installation of Windows 98 on a new system

Click on "Hibernate" and select "Enable Hibernate Support" then "Apply". c. Click on the "Advanced" tab, you'll see "Hibernate" on "Power Buttons". Note that this option will only be seen after step b mentioned above has been completed, otherwise only "Standby" and "Shutdown" will be shown. Select "Hibernate" and "Apply". 3. Clean boot into DOS and run AOZVHDD utility. a. If you assign the whole disk to your Win 98 system (FAT 16 or FAT 32), please run "aozvhdd /c /file". Please remember sufficient free space has to be reserved in the disk, e.g. if you have 64 MB DRAM and 16 MB VGA card installed, the system needs at least 80 MB free space. The utility will locate the space automatically. b. If you assign an individual partition for Win 98, please run "aozvhdd /c /partition". Of course, the system needs to provide unformatted an empty partition. 4. Reboot system. 5. You've already implemented ACPI Suspend to-Hard Drive. Click "Start > Shut Down > Standby" then the screen will go off immediately. And 1 minute or so will be taken for the system to save what's in the memory to the hard drive; the larger the memory size the longer this process will take.

Changing from APM to ACPI (Windows 98 only)

MX36LE-U / MX36LE-UN BI O S U p g r a d e
By flashing your motherboard, you agree to accept the possibility of BIOS flash failure. If you motherboard is working and is stable, and there are no major bugs that were fixed by a latter BIOS revision, we recommend that you DO NOT try to upgrade your BIOS. By doing so, you are taking a risk of BIOS flash failure. If you indeed intent on upgrading, PLEASE BE SURE to use the right BIOS revision for the right motherboard model. AOpen Easy Flash is a little different than traditional flash method. The BIOS binary file and flash routine are linked together and you simply run a single commend to complete the flash process. Caution: AOpen Easy Flash BIOS programs are designed to be compatible with the Award BIOS. At the date of this note, AOpen Easy Flash BIOS programs are not available for AMI BIOS. AMI BIOS appears mostly only on old 486 boards and some early Pentium boards. Please be sure to view the README compressed inside the BIOS package before upgrading, and follow upgrade instructions carefully. This will minimize the chance of flash failures.
Below are the steps for easy flashing procedures: (applies for Award BIOS ONLY) 1. 2. Download new BIOS upgrade zip file from AOpen's web site. For example, MX36LEUN102.ZIP.
Run shareware PKUNZIP ( which supports miscellaneous operation systems to extract the binary BIOS file and the flash utility. Or Winzip ( in Windows environment. Save the unzipped file into a bootable floppy disk. For example, MX36LEUN102.BIN & MX36LEUN102.EXE Reboot the system to DOS mode without loading any memory handler (such as EMM386) or device driver. It needs around 520K free memory spaces. Execute A:> MX36LEUN102 and the program will do the rest of it. DO NOT turn off the power during FLASH PROCESS until you are asked to!! Reboot system and press <Del> to enter BIOS setup, Choose "Load Setup Defaults", then Save & Exit Setup. Done!

3. 4. 5. 6.

Warning: The new BIOS upgrade will permanently replace your original BIOS's settings and PnP information when flashing. You may need to reconfigure your BIOS setting and re-install Win95/Win98 as well as your add-on cards, so that your system can go back to work as normal.

O v e r cl o c k i n g

As a leading manufacturer in motherboard industry, AOpen always listens to what customers want and develop products to fit different user's requirements. Reliability, compatibility, leading technology and friendly features are our basic goals when designing motherboards. Other than above mentioned design criteria, there are power users who are always seeking to push the limitation of the system performance by overclocking which we call them "Overclocker". This section is dedicated to overclockers. This high performance motherboard is designed for maximum 133MHz CPU bus clock. But it comes with clock generator of 150MHz when we design it to accommodate future CPU bus clock. Our lab test results shown that 150MHz is achievable when proper setting and qualified components were presented, we feel quite comfortable overclocking to 150MHz. Not only that, this motherboard has full-range (CPU core voltage) settings and an option to adjust CPU core voltage. The CPU clock ratio can be up to 16x that supports almost all of Pentium III/Celeron CPUs in the future and provides flexibility for overclockers. For your reference, the following configurations are what we feel comfortable at 150MHz bus clock.

But not guarantee.

Warning: The design of this product follows CPU and chipset vendor's design guideline. Any attempts to push beyond product specification are not recommended and you are taking your own risk to damage your system or important data. Before doing overclocking, you must make sure your components are able to tolerate such abnormal setting, especially CPU, DRAMs, hard disks, and AGP VGA cards.
Tip: Note that overclocking may also cause thermal problem. Please make sure that the cooling fan and the heatsink were adequate to dissipate excessive heat that's generated by overclocking the CPU.


ATA/66 uses both rising edge and falling edge but doubles UDMA/33 transfer rate. The data transfer rate is 4 times of the PIO mode 4 or DMA mode 2, 16.6MB/s x4 = 66MB/s. To use ATA/66, you need special ATA/66 IDE cable.


ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 40ns. The data transfer rate is (1/40ns) x 2 bytes x 2 = 100MB/s. To use ATA/100, you need special 80-wire IDE cable, the same as ATA/66.
B I O S ( Ba s i c I n p u t / O u t p u t S y s t e m )
BIOS is a set of assembly routine/program that reside in EPROM or Flash ROM. BIOS controls Input/output devices and other hardware devices of motherboard. In general, to provide hardware independent portability, operation system and drivers is required to access BIOS without directly access hardware devices.
B us M a s t e r I D E ( D M A m o de )
The traditional PIO (Programmable I/O) IDE requires the CPU to involve in all the activities of the IDE access including waiting for the mechanical events. To reduce the workload of the CPU, the bus master IDE device transfers data from/to memory without interrupting CPU, and releases CPU to operate concurrently while data is transferring between memory and IDE device. You need the bus master IDE driver and the bus master IDE HDD to support bus master IDE mode.
C N R ( C o m m un i c a t i o n a n d Ne t w o r k i n g R i s e r )
The CNR specification provides the PC industry the opportunity to deliver a flexible and cost reduced method of implementing LAN, home networking, DSL, USB, wireless, audio and modem subsystems widely used in today's "connected PCs". The CNR specification is an open industry specification and is supported by OEMs, IHV card manufacturers, silicon supplier and Microsoft.
C O DE C ( C o d i n g a n d De c o di n g )
Normally, CODEC means a circuit that can do digital to analog conversion and also the analog to digital conversion. It is part of AC97 sound/modem solution.
D I M M ( D ua l I n L i ne M e m o r y M o d u l e )
DIMM socket has total 168-pin and supports 64-bit data. It can be single or double side, the golden finger signals on each side of PCB are different, that is why it was called Dual In Line. Almost all DIMMs are made by SDRAM, which operate at 3.3V. Note that some old DIMMs are made by FPM/EDO and only operate at 5V. Do not confuse them with SDRAM DIMM.
E C C ( E r r or C he c k i n g a n d C or r e c t i o n )
The ECC mode needs 8 ECC bits for 64-bit data. Each time memory is accessed; ECC bits are updated and checked by a special algorithm. The ECC algorithm has the ability to detect double-bit error and automatically correct single-bit error while parity mode can only detect single-bit error.

P a r i t y Bi t

The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated, parity bit will be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the parity error is occurred and this is called single bit error detection.
P BS R A M ( P i p e l i n e d B u r s t S R A M )
For Socket 7 CPU, one burst data read requires four QWord (Quad-word, 4x16 = 64 bits). PBSRAM only needs one address decoding time and automatically sends the remaining QWords to CPU according to a predefined sequence. Normally, it is 3-1-1-1, total 6 clocks, which is faster than asynchronous SRAM. PBSRAM is often used on L2 (level 2) cache of Socket 7 CPU. Slot 1 and Socket 370 CPU do not need PBSRAM.

P C -0 D I M M

SDRAM DIMM that supports 100MHz CPU FSB bus clock.

P C -3 D I M M

SDRAM DIMM that supports 133MHz CPU FSB bus clock.
P CI ( P e r i ph e r a l C o m p o ne n t I n te r f a c e ) B u s
Bus for the internal connection of peripheral devices, high-speed data channel between the computer and expansion card.

P D F F o r ma t

A file format for electronic document, PDF format is independent from platform, you can read PDF file under Windows, Unix, Linux, Mac with different PDF reader. You can also read PDF file by web browser such as IE and Netscape, note that you need to install PDF plug-in first (Included in Acrobat Reader).
P nP ( P l u g a n d P l a y )
The PnP specification suggests a standard register interface for both BIOS and operating system (such as Windows 95). These registers are used by BIOS and operating system to configure system resource and prevent any conflicts. PnP BIOS or operating system will automatically allocate the IRQ/DMA/Memory. Currently, almost all the PCI cards and most ISA cards are already PnP compliant.
POST (Power-On Self Test)
The BIOS self-test procedure after power-on, sometimes, it is the first or the second screen shown on your monitor during system boot.
R D R A M ( R a mb u s D R A M )


UltraATA (or, more accurately, UltraATA/33) is a protocol for transferring data between a hard disk drive through the computers data path (or bus) to the computers random access memory (RAM). The UltraATA/33 protocol transfers data in burst mode at a rate of 33.3MB/s, twice as fast as the previous Direct Memory Access (DMA) interface. UltraATA was developed as a proposed industry standard by the Quantum corporation, makes of hard disk drives, and Intel, makes of chipset that support computer bus technology. UltraATA support in your computer means that it will boot (start) and open new applications more quickly. It will help users of graphic-intensive and applications that require large amounts of access to data on the hard disk drive. UltraATA uses Cyclical Redundancy Checking (CRC), offering a new level of data protection. UltraATA uses the same 40-pin IDE interface cable as PIO and DMA. 16.6MB/s x2 = 33MB/s 16.6MB/s x4 = 66MB/s 16.6MB/s x6 = 100MB/s
U S B ( U n i v e rs a l S e r i a l B us )
USB is a 4-pin serial peripheral bus that is capable of cascading low/medium speed peripherals (less than 10Mbit/s) such as keyboard, mouse, joystick, scanner, printer and modem. With USB, the traditional complex cables from back panel of your PC can be eliminated.
VCM (Virtual Channel Memory)
NECs Virtual Channel Memory (VCM) is a new DRAM core architecture that dramatically improves the memory systems ability to service multimedia requirements. VCM increases memory bus efficiency and performance of any DRAM technology by providing a set of fast static registers between the memory core and I/O pins. Using VCM technology results in reduced data access latency and reduced power consumption.
