2. FEATURES Performance 2. FEATURES 2.1.2 Specifications - Optional Components The following onboard components are optional at the time of purchase: • Onboard Audio: AC97 V2.1 compliant Audio Codec with 3D sound circuitry and sample rate conversion from 7kHz to 48kHz. 2.1.3 Performance • 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 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/SDRAM Optimized Performance: This motherboard supports a new generation memory, NEC's 64Mb Virtual Channel Memory (VCM) Synchronous Dynamic Random Access Memory (SDRAM), which 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 standard SDRAM, which increases the data transfer rate (1.064GB/s max using PC133-compliant SDRAMs and 800MB/s max using PC100-compliant SDRAMs).• New Compliancy: Both the BIOS and hardware levels of ASUS smart series motherboards meet PC'99 compliancy. The new PC'99 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 Windows 95/98/NT. Color-coded connectors and descriptive icons make identification easy as required by PC'99. • 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. 10 ASUS CUA User's Manual

Specifications — Optional Components
The following onboard components are optional at the time of purchase:
•
Onboard Audio:
AC97 V2.1 compliant Audio Codec with 3D sound circuitry
and sample rate conversion from 7kHz to 48kHz.

•
Concurrent PCI:
Concurrent PCI allows multiple PCI transfers from PCI mas-
ter busses to the memory and processor.
•

This motherboard supports a new gen-
eration memory, NEC’s 64Mb Virtual Channel Memory (VCM) Synchronous
Dynamic Random Access Memory (SDRAM),
which is compatible to the indus-
try standard SDRAM. The VCM’s core design provides up to 50% higher

ant SDRAMs).
• New Compliancy:
Both the BIOS and hardware levels of ASUS
smart series motherboards meet PC’99 compliancy. The new PC’99 require-
ments 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 Windows 95/98/NT. Color-coded connectors and descriptive icons
make identification easy as required by PC’99.
