2.1.3Special 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 98/2000/Millenium 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.

•New Compliancy: Both the BIOS and hardware levels of this 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 Windows95/98/NT . Color-coded connectors and descriptive icons make identification easy as required by PC 99.

2.1.4 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/100 increases the data transfer rate to 100MB/s. UltraDMA/100 is backward compatible with DMA/66, 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. (UltraDMA100/66 require a 40-pin80-con- ductor cable to be enabled.)

•DDR SDRAM Optimized Performance: This motherboard supports a new gen- eration memory, Double Data Rate (DDR) Dynamic Random Access Memory (SDRAM), which is compatible to the industry standard SDRAM. This new memory technology increases performance by executing two actions per clock cycle, resulting in data transfer rates of up to 2.1 GB/s for 133MHz DDR SDRAM and 1.6GB/s for 100MHz DDR SDRAM.
