2.1.3 Performance
• UltraPerformance: 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.
• High-Speed Data Transfer Interface: IDE transfers using UltraDMA/66 Bus
Master IDE can handle rates up to 66.6MB/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. (UltraDMA/66/100 requires a 40-pin 80-
conductor cable to be enabled.)
• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter buses to memory and processor.
• 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
98/2000/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.
2.1.2 Specifications–Optional Components
The following onboard components are optional at the time of purchase:
• Smart Audio: AC97 V2.1 compliant Audio Codec with sample rate conversion
from 7kHz to 48kHz.
