2.1.3 Performance
•
Onboard LED: The onboard LED will light up when there is standby power to
the motherboard. This acts as a reminder to the user to turn OFF the power
before plugging and unplugging devices so as not to damage the motherboard,
peripherals, and/or components.
•
UltraPerformance: Onboard IDE Bus Master controller with two connectors that
support four IDE devices in two channels. Supports UltraDMA/100, UltraDMA/
66, UltraDMA/33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced
IDE devices:DVD-ROM, CD-ROM, CD-R/RW, LS-120, and Tape Backup drives.
•
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 1066MB/s max.
•
ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-
mented on all smart series motherboards. ACPI provides more Energy Saving
Features for operating systems (OS) supporting OS Direct Power Management
(OSPM). With these features implemented in the OS, PCs can be ready around
the clock, yet satisfy all the energy saving standards. To gain all the benefits, an
ACPI-supported OS, such as Windows 98/2000/ME is required.
•
Audio CODEC. This AC ‘97 audio codec provides stereo analog I/O on the
motherboard and peripheral devices to deliver high quality audio to PC-con-
nected speakers, headphones, and microphones. The codec includes analog-to-
digital and digital-to-analog sample rate converters, as power amplifiers and
programmable gain blocks.
•
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 high-level goals: support for Plug and
Play compatibility and power management for managing all system compo-
nents, and 32-bit device drivers and installation procedures for Windows 95/98/
NT. Color-coded connectors and descriptive icons make identification easy.
