2.1.3Performance Features

•High-Speed Data Transfer Interface: Onboard IDE Bus Master controller with two connectors that support four IDE devices in two channels. Supports UltraDMA/100/66, 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. 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. (UltraDMA/66/100 requires a 40-pin 80-conductor cable to be enabled.)

•RDRAM Optimized Performance: This motherboard supports the new gen- eration memory, Rambus Dynamic Random Access Memory (RDRAM). While PC100 SDRAM modules operate at 100MHz with a peak bandwidth of 0.8GB/s, MCH dual channel Rambus DRAMs can operate at up to 400MHz with a peak bandwidth of 3.2GB/s.

•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 realize the benefits of ACPI, an ACPI-supported OS, such as Windows 98/ 2000/Millenium, must be used.

•Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings

as an alternative to leaving the computer ON and QuickStart™ so that you do not have to wait for a long time for system bootup.

•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.
