2. FEATURES

Smart Series

• UltraDMA/66 & UltraDMA/33: Comes with an onboard PCI Bus Master IDE

controller with two connectors that support four IDE devices on two channels.

Supports UltraDMA/66, UltraDMA/33, PIO Modes 3 & 4 and Bus Master IDE

DMA Mode 2, and Enhanced IDE devices, such as Tape Backup, CD-ROM, CD-

R/RW, and LS-120 drives.

2.1.2 Performance

• 66/100MHz Asynchronous & 100/100MHz Synchronous Host/DRAM Clock

Support: CPU frequency can operate at 66MHz or 100MHz while system

memory operates at 100MHz or 66MHz. This can optimize the VGA perfor-

mance under shared memory configuration.

• High-Speed Data Transfer Interface: This motherboard with its chipset and

support for Ultra DMA/66 doubles the Ultra DMA/33 burst transfer rate to

66.6MB/s. Ultra DMA/66 is backward compatible with both DMA/33 and DMA

and with existing DMA devices and systems so there is no need to upgrade cur-

rent EIDE/IDE drives and host systems. (Ultra DMA/66 requires a 40-pin 80-

conductor cable to be enabled and/or for Ultra DMA Mode 4.)

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter buses to memory to CPU.

• SDRAM Optimized Performance: ASUS smart series motherboards support

the new generation memory, Synchronous Dynamic Random Access Memory

(SDRAM), which increases the data transfer rate to 800MB/s max using PC100-

compliant SDRAM.

• 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.

• PC’98 Compliant: Both the BIOS and hardware levels of the motherboard meets

PC’98 compliancy. The new PC’98 requirements for systems and components 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.
