2.FEATURES

2.1.2Special 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.

•PC’98 Compliant: Both the BIOS and hardware levels of ASUS smart series motherboards meet PC’98 compliancy. The 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 procedures for Windows95/98/NT .

•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 its chipset and support for UltraDMA/66 doubles the UltraDMA/33 burst transfer rate to 66.6MB/s. UltraDMA/66 is backward compatible with both DMA/33 and DMA and with existing DMA devices and systems so there is no need to upgrade current EIDE/IDE drives and host systems. (UltraDMA/66 requires a 40-pin80-conductor cable to be enabled and/or for UltraDMA Mode 4.)

•VCM/HSDRAM Optimized Performance: Supports the new generation memory, NEC’s Virtual Channel (VC) SDRAMs (Synchronous Dynamic Ran- dom Access Memory) or Enhanced Memory System’s High-speed DRAMs (HSDRAMs) for higher system performance at minimal cost premium.
