2.1.3 Special 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
• 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-pin 80-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.
