Specifications	2.FEATURES

2.FEATURES

2.1The ASUS MEW-AM Motherboard

The MEW-AM motherboard from ASUS is designed for the new PC user who wants simple features in a small package.

2.1.1 Specifications

•Latest Intel Socket 370 Processor Support! Supports Intel’s Celeron processor designed for Socket 370 and packaged in Plastic Pin Grid Array (PPGA).

•Latest Intel 810-DC100 Chipset! The 810-DC100 (GMCH+ICH) supports 66/ 100MHz FSB, UltraDMA/66, and 4MB 32-bit 100MHz SDRAM display cache controller.

•Integrated Graphics! Controller supports 3D hyper pipelined architecture, parallel data processing and compression, precise pixel interpolation, full 2D hardware acceleration, and motion video acceleration. Optional onboard 4MB SDRAM display cache allows up to 1024x768x16bit color for 3D graphics and 1600x1200x8bit color for 2D graphics.

•ASUS Graphics Driver! You can gain about 12% performance over that of the standard graphics driver (2D highend graphics WinMark) using ASUS’ custom graphics driver. ASUS custom graphics driver also provides more features and provides selection of higher refresh rates and resolutions.

•Versatile Memory Support! DRAM controller supports asymmetrical addressing and two DIMM sockets support Intel PC100-compliant SDRAMs (16, 32, 64, 128, or 256MB) up to 512MB. (supports a maximum of 4 sides)

•Latest Low Pin Count Multi-I/O: Provides two high-speed UART compatible serial ports and one parallel port with EPP and ECP capabilities.

•Integrated IDE! Controller supports UltraDMA/66 up to 66MB/s, UltraDMA/ 33 up to 33MB/s, and PIO Mode 4 up to 17MB/s.

•Desktop Management Interface (DMI) V2.3! Supports DMI through BIOS, which allows hardware to communicate within a standard protocol creating a higher level of compatibility. (Requires DMI-enabled components.)

•Peripheral Wake-Up! Supports Wake-On-LAN, Wake-On-Ring, and BIOS Wake-Up.

•Firmware Hub! Provides security and other latest power computing features.

•Smart BIOS! 4Mb firmware gives a new easy-to-use interface which provides more control and protection over the motherboard. Provides boot block write protection and HD/SCSI/MO/ZIP/CD/Floppy boot selection. Hardware random number generator supports new security software for data protection and secured Internet transactions.

•Enhanced ACPI & Anti-Boot Virus Protection! Programmable BIOS (Flash EEPROM), offering enhanced ACPI for Windows 98 compatibility, built-in firm- ware-based virus protection, and autodetection of most devices for virtually automatic setup.

8	ASUS MEW-AM User’s Manual

2.FEATURES

•Highest Audio Quality! AC’97 DAC/ADC (software audio) built into the audio codec reduces noise to improve audio quality and performance for a SNR (signal to noise ratio) of +90dB. These features greatly improve voice synthesis and recognition. If more quality is required, an optional onboard Crystal PCI audio improves audio quality beyond software audio.

2.1.2 Performance

•UltraPerformance! Onboard IDE Bus Master controller with two connectors that support four IDE devices in two channels. Supports UltraDMA/66, UltraDMA/33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced IDE devices, such as Tape Backup, CD-ROM, CD-R/RW, and LS-120 drives.

•Dual Speeds! CPU frequency can operate at either 66MHz or 100MHz while system memory operates at either 100MHz or 66MHz. (100MHz CPU with 66MHz SDRAM setting not supported) This asynchronous design can optimize the VGA performance under shared memory configuration. Of course 100MHz/100MHz synchronous host/DRAM clock is recommended for maximum performance.

•Double or Quadruple the IDE Transfer Speed! IDE transfers using UltraDMA/ 33 Bus Master IDE can handle rates up to 33MB/s and up to 66MB/s using UltraDMA/66 technology. The best of all is that these new technology is compatible with existing ATA-2 IDE specifications so there is no need to upgrade current IDE devices or cables.

•Concurrent PCI! Concurrent PCI allows multiple PCI transfers from PCI master buses to memory to CPU.

•SDRAM Optimized Performance! ASUS smart series motherboards support the new generation memory, Synchronous Dynamic Random Access Memory (SDRAM), which increases the data transfer rate to 800MB/s max using PC100 SDRAM.

•ACPI Ready! ACPI (Advanced Configuration and Power Interface) is also implemented on all ASUS smart series motherboards. ACPI provides more Energy Saving Features for future operating systems (OS) supporting OS Direct Power Management (OSPM) functionality. With these features implemented in the OS, PCs can be ready around the clock, yet satisfy all the energy saving standards. To fully utilize the benefits of ACPI, an ACPI-supported OS such as Windows 98 must be used.

•Extreme Graphics! The integrated motion compensation allows for smooth MPEG1 or MPEG2 video playback. Fast 3D graphics engine allows for an exciting gameplay experience.

3.HARDWARE SETUP

3.4Motherboard Settings

WARNING! Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer.

1.Unplug your computer when working on the inside.

2.Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case.

3.Hold components by the edges and try not to touch the IC chips, leads or connectors, or other components.

4.Place components on a grounded antistatic pad or on the bag that came with the component whenever the components are separated from the system.

1)CPU External Frequency Setting (FS0, FS1, FS2, FS3, FS4)

Current PCI bus is limited to 33MHz, Socket 370 Celeron processors limited to 66MHz, and SDRAM limited to the DIMM type 66/100/133MHz. (66MHz SDRAM is not supported on this motherboard.) Other settings are for experienced users only.

Recommended

CPU Setting

NOTE: For updated processor settings, please visit ASUS’ web site (see ASUS CONTACT INFORMATION)

WARNING! CPU frequencies above 66MHz exceed the specifications for current Celeron processors and are not guaranteed to be stable. Premature wearing of the processor may result when overclocking. Be sure that the DIMM you use can handle the specified SDRAM MHz or else bootup will not be possible.

14	ASUS MEW-AM User’s Manual

3.HARDWARE SETUP

3.5System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.

This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM).

This chipset does not support ECC. However, ECC memory modules may still be used, but the ECC function will not be available.

Install memory in any combination as follows:

Location	168-pin DIMM SDRAM		Total Memory
DIMM1	Single-Sided/Double-Sided	x1
(Rows 0&1)	16, 32, 64, 128MB, or 256MB
DIMM2	Single-Sided/Double-Sided	x1
(Rows 2&3)	16, 32, 64, 128MB, or 256MB
	Total System Memory (Max 512MB)	=

NOTE: At the time this User’s Manual was written, 256MB DIMMs are only available as Double-Sided registered memory (128Mbit cells). Using 2x2x2 SDRAM can greatly improve the onboard graphics’ performance.

3.5.1 General DIMM Notes

•This motherboard operates at 100MHz, therefore PC100-compliant modules must be used because of the strict timing issues involved under this speed.

•ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability.

•SDRAM chips are generally thinner with higher pin density than EDO (Extended Data Output) chips.

•BIOS shows SDRAM memory on bootup screen.

•Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64, 128, 256MB.

3.5.2DIMM Installation

Insert the module(s) as shown. Because the number of pins are different on either side of the breaks, the module will only fit in the orientation shown. DIMM modules are longer and have different pin contact on each side and therefore have a higher pin density. SIMMs have the same pin contact on both sides.

MEW-AM 168-Pin DIMM Sockets

The DIMMs must be 3.3V Unbuffered for this motherboard. To determine the DIMM type, check the notches on the DIMMs (see figure below).

168-Pin DIMM Notch Key Definitions (3.3V)

		DRAM Key Position		Voltage Key Position

RFU	Unbuffered	5.0V	Reserved
Buffered			3.3V

The notches on the DIMM will shift between left, center, or right to identify the type and also to prevent the wrong type from being inserted into the DIMM slot on the motherboard. You must ask your retailer the correct DIMM type before purchasing. This motherboard supports four clock signals per DIMM slot.

16	ASUS MEW-AM User’s Manual

3.HARDWARE SETUP

3.6Central Processing Unit (CPU)

The motherboard provides a ZIF Socket 370. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not the case, then purchase a fan before you turn on your system.

WARNING! Be sure that there is sufficient air circulation across the processor’s heatsink by regularly checking that your CPU fan is working. Without sufficient circulation, the processor could overheat and damage both the processor and the motherboard. You may install an auxiliary fan, if necessary.

To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and open it by first pulling the lever sideways away from the socket then upwards to a 90-degree angle. Insert the CPU with the correct orientation as shown. The notched corner should point towards the end of the lever. Because the CPU has a corner pin for two of the four corners, the CPU will only fit in the orientation as shown. The picture is for reference only; you should have a CPU fan that covers the face of the CPU. With the added weight of the CPU fan, no force is required to insert the CPU. Once completely inserted, close the socket’s lever while holding down the CPU.

NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency multiple setting is available only on unlocked processors) for your Socket 370 processor or else boot-up may not be possible.

CAUTION! Be careful not to scrape the motherboard when mounting a clampstyle processor fan or else damage may occur to the motherboard.

WARNING! Some pins are used for connectors or power sources. These are clearly distinguished from jumpers in the Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard.

IMPORTANT: Ribbon cables should always be connected with the red stripe to Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on floppy disk drives. Check the connectors before installation because there may be exceptions. Look on IDE ribbon cable must be less than 46 cm (18 in.), with the second drive connector no more than 15 cm (6 in.) from the first connector.

1)PS/2 Mouse Connector (6-pin PS2KBMS)

The system will direct IRQ12 to the PS/2 mouse if one is detected. If one is not detected, expansion cards can use IRQ12.

9)Primary / Secondary IDE Connectors (Two 40-1pin IDE)

These connectors support the provided IDE hard disk ribbon cable. After connecting the single end to the board, connect the two plugs at the other end to your hard disk(s). If you install two hard disks, you must configure the second drive to Slave mode by setting its jumper accordingly. Please refer to your hard disk documentation for the jumper settings. (Pin 20 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 20 plugged).

TIP: You may configure two hard disks to be both Masters with two ribbon cables – one for the primary IDE connector and another for the secondary IDE connector and select the boot disk through Boot Sequence in 4.7 Boot Menu.

IMPORTANT: UltraDMA/66 IDE devices must use an 80-wire IDE cable or else devices will automatically be limited to UltraDMA/33 mode.

13)CPU Fan Connectors (3-pin CPU_FAN)

This connector supports a cooling fan of 350mA (4.2 Watts) or less. Orientate the fan so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan’s plug to the board taking into consideration the polarity of the connector.

NOTE: The “Rotation” signal cannot be monitored on this motherboard.

WARNING! The CPU and/or motherboard will overheat if there is no airflow across the CPU and onboard heatsinks. Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. These are not jumpers, do not place jumper caps over these pins.
