Performance - Asus ME-99B User Manual

2.1.2 Performance

• 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.
• 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.
• 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 this new technology is compat-
ible with existing ATA-2 IDE specifications so there is no need to upgrade cur-
rent IDE devices.
• 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.
