2. FEATURES
2.1.2 Special Features
• ACPI Support: 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 are PC’99 compliant. The new PC’99 requirements for systems
and components are based on the following high-level goals: Support for Plug-
n-Play compatibility and power management for configuring and managing all
system components, and 32-bit device drivers and installation procedures for
Windows95/98/NT . Color-coded connectors and descriptive icons make
identification easy as required by PC’99.
2.1.3 Performance Features
• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master
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 with
existing DMA devices so there is no need to upgrade current EIDE/IDE drives.
(UltraDMA/66 requires a 40-pin 80-conductor cable).
• VCM/SDRAM Optimized Performance: This motherboard supports the new
generation memory, NEC 64Mb Virtual Channel Memory (VCM) Synchronous
Dynamic Random Access Memory (SDRAM), that is compatible to the industry
standard SDRAM. The VCM’s core design provides up to 50% higher SDRAM
speed at reduced power consumption of about 30%. This motherboard also
supports the standard SDRAM for a the data transfer rate of up to 1.064GB/s using
PC133-compliant SDRAMs and up to 800MB/s using PC100-compliant
SDRAMs).
