PC/100-compliant SDRAMs (8, 16, 32, 64, 128, or 256MB) up to 768MB. These

new SDRAMs are necessary to meet the 95MHz/100MHz bus speed requirement.

•AGPSlot: SupportsAGPcards for high performance, component level interconnec-

tion targeted at 3D graphical display applications.

•Ultra DMA/33 BM IDE: Comes with an onboard PCI Bus Master IDE controller

lows hardware to communicate within a standard protocol creating a higher level of

compatibility. (Requires DMI-enabled components.) (See section V)

•Level2CacheSRAM/TagRAM:Supports512KB/1024KBpipelined-burstSRAM/L2

memory cache and integrated Tag RAM to make using the 100MHz bus speed possible.

Smart Series

Introduction to ASUS Smart Series of Motherboards

Performance

• SDRAM Optimized Performance: ASUS Smart Series of motherboards sup-

port the new generation memory—Synchronous Dynamic Random Access

Memory (SDRAM)—which increases the data transfer rate from 264MB/sec

maximum using EDO memory to 528MB/sec max using SDRAM.

• Double the IDE Transfer Speed: ASUS Smart Series of motherboards with

ALi’s Aladdin V chipset improves IDE transfer rate using UltraDMA/33 Bus

Master IDE, which can handle data transfer up to 33MB/sec. The best of all is

that this new technology is compatible with existing ATA-2 IDE specifications

so there is no need to upgrade current hard drives or cables.

•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter buses to memory to CPU.

• ACPIReady:ACPI(AdvancedConfiguration and PowerInterface)isalso imple-

mented on allASUS Smart Series of motherboards.ACPI provide more Energy

Saving Features for the 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 ofACPI, an OS that supports ACPI, such

as Windows 98, must be used.

• PC’98 Compliant: Both the BIOS and hardware levels of the ASUS smart

motherboard series meet PC’98 compliancy. The new PC’98 requirements for

systems and components are based on the following high-level goals: Support

for Plug and Play compatibility and power management for configuring and

managing all system components, and 32-bit device drivers and installation pro-

cedures for Windows 95/Windows 98 and Windows NT.

Intelligence (with optional Hardware Monitor only)

• Fan Status Monitoring and Alarm: To prevent system overheat and system

damage, the CPU fan and system fans are monitored for RPM and failure. Each

fan can be set for its normal RPM range and alarm thresholds.

•Temperature Monitoring and Alert: To prevent system overheat and system

damage, there is a heat sensor under the CPU and on the motherboard itself to

monitor CPU and system temperature to make sure the system is operating at a

safe heat level to avoid any failures triggered by extremely high temperature.

II. FEATURES

P5A-B Series

II. FEATURES

•Voltage Monitoring and Alert: System voltage levels are monitored to ensure

stable current to critical motherboard components. Voltage specifications are

more critical for future processors, so monitoring is necessary to ensure proper

system configuration and management.

• SystemResourcesAlert:Today’s operating systems, such as Windows 95,Win-

dows NT, and OS/2, require much more memory and hard drive space to present

enormous user interfaces and run large applications. The system resource moni-

tor will warn the user before the system resources are used up to prevent pos-

sible application crashes. Suggestions will give the user information on manag-

ing their limited resources more efficiently.

• CPU Slow Down: When CPU fans or system fans are malfunctioning, the sys-

tem will deactivate the CPU Clock line to decrease CPU utilization to the speed

upon detection of system overheat. This will prevent CPU damage from system

overheat. The CPU utilization will restore normal operations when temperature

falls below a safe level.

• Auto Fan Off: The system fans will power off automatically even in sleep

mode.This function reduces both energy consumption and system noise, and is

a important feature to implement silent PC systems.

• Dual Function Power Button (requires ATX power supply): The system can

be in one of two states, one is Sleep mode and the other is Soft-Off mode. Pushing

the power button for less than 4 seconds places the system into Sleep mode.When

the power button is pressed for more than 4 seconds, it enters the Soft-Off mode.

• Remote Ring On (requiresATX power supply):This feature allows a computer

to be turned on remotely through a modem. With this benefit on hand, any user

can access vital information from their computer from anywhere in the world!

• Message LED (requires ACPI-supported OS): Chassis LEDs now act as in-

formation providers. Through the way a particular LED illuminates, the user

can determine the stage the computer is in. A simple glimpse provides useful

information to the user.
