2.1.2 Special Features

• ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more

Energy Saving Features for operating systems that support 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.

• Easy Installation: Incorporates BIOS that supports autodetection of hard disk

drives, PS/2 mouse, and Plug and Play devices to make the setup of hard disk

drives, expansion cards, and other devices virtually automatic.

• New Compliancy: Both the BIOS and hardware levels of this motherboard meet

the stringent requirements for PC’99 certification. The new PC’99 requirements

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

port for Plug and Play compatibility and power management for configuring

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

procedures for Windows 95/98/NT. Color-coded connectors and descriptive icons

make identification easy as required by PC’99.

• Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards through

the onboard SYMBIOS firmware.

2.1.3 Performance Features

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

ter busses to the memory and processor.

• High-Speed Data Transfer Interface: IDE transfers using UltraDMA/33 Bus

Master IDE can handle rates up to 33MB/s. This motherboard with a CMD

UltraDMA/66 IDE controller and support for UltraDMA/66 doubles the

UltraDMA/33 burst transfer rate to 66.6MB/s. UltraDMA/66 is backward com-

patible with both DMA/33 and DMA and with existing DMA devices and sys-

tems so there is no need to upgrade current EIDE/IDE drives and host systems.

(UltraDMA/66 requires a 40-pin 80-conductor cable to be enabled and/or for

UltraDMA Mode 4.)

• SDRAM Optimized Performance: Supports the new generation memory - Syn-

chronous Dynamic Random Access Memory (SDRAM) which increases the data

transfer rate to 800MB/s max using PC100-compliant SDRAM.
