2.1.3 Performance
• 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-pin
80-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 to CPU.
• 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,
Rambus DRAMs can operate at up to 800MHz with a peak bandwidth of 1.6GB/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 fully utilize the benefits of ACPI, an ACPI-supported OS, such as Windows
98, 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 fall asleep waiting for system bootup.
• PC 99 Compliancy: Both the BIOS and hardware levels of the motherboard
meet PC 99 compliancy. The new PC 99 requirements for systems and compo-
nents 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.
