2.1.3Performance

•UltraPerformance: Onboard IDE Bus Master controller with two connectors that support four IDE devices in two channels. Supports UltraDMA/66, UltraDMA/33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced IDE devices, such as DVD-ROM, CD-ROM, CD-R/RW, LS-120, and Tape Backup drives.

•Dual Speeds: CPU frequency can operate at either 133MHz or 100MHz.

•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.)

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

•SDRAM Optimized Performance: This motherboard supports PC133-com- pliant Synchronous Dynamic Random Access Memory (SDRAM), which increases the data transfer rate to 1066MB/s max.

•ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple- mented on all ASUS smart series motherboards. ACPI provides more Energy Saving Features for future operating systems (OS) supporting 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 98/2000/Millenium, must be used.

•New Compliancy: Both the BIOS and hardware levels of the 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/NT and later. Color-coded connectors and descrip- tive icons make identification easy as required by PC 99.
