2. FEATURES
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.
• PC’99 Compliant: Both the BIOS and hardware levels of ASUS smart series
motherboards meet PC’99 compliancy. The new PC’99 requirements for sys-
tems and components are based on the following high-level goals: Support for
Plug and Play compatibility and power management for configuring and man-
aging all system components, and 32-bit device drivers and installation proce-
dures 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 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-pin
80-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.
