2.1.3 Performance
• UltraPerformance: Onboard IDE Bus Master controller with two connectors that
support four IDE devices in two channels. Supports UltraDMA100//66/33, (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.
• 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 100MB/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.
