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 Tape Backup, CD-ROM, CD-R/RW, and LS-120 drives.
• Dual Speeds! CPU frequency can operate at either 66MHz or 100MHz while
system memory operates at either 100MHz or 66MHz. (100MHz CPU with
66MHz SDRAM setting not supported) This asynchronous design can optimize
the VGA performance under shared memory configuration. Of course 100MHz/
100MHz synchronous host/DRAM clock is recommended for maximum per-
formance.
• Double or Quadruple the IDE Transfer Speed! IDE transfers using UltraDMA/
33 Bus Master IDE can handle rates up to 33MB/s and up to 66MB/s using
UltraDMA/66 technology. The best of all is that these new technology is com-
patible with existing ATA-2 IDE specifications so there is no need to upgrade
current IDE devices or cables.
• 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.
• Suspend and Go! Suspend-to-RAM (STR) and suspend-to-disk provides maxi-
mum power savings as an alternative to leaving the computer ON and
QuickStart™ so that you do not fall asleep waiting for system bootup. (STR
requires OS support and does not support ISA cards; ISA cards may fail to work
coming out of STR mode.)
• Windows 2000 Ready! The new-generation operating system provides smart
management, web integration, multilanguage support, and higher level of per-
formance, reliability, and security.
• Highest Audio Quality! AC’97 DAC/ADC built into the audio CODEC re-
duces noise to improve audio quality and performance for a SNR (signal to
noise ratio) of +90dB. These features greatly improve voice synthesis and rec-
ognition.
• Extreme Graphics! The integrated motion compensation allows for smooth
MPEG1 or MPEG2 video playback. Fast 3D graphics engine allows for an ex-
citing gameplay experience.
