Introduction

The Anaheim2A Micro ATX motherboard offers a time to market consumer and corporate desktop solution featuring the Intel Celeron PPGA or FC-PGA processor with 66/100MHz front side bus and the Whitney chipsets in a Micro ATX low profile motherboards. In addition, the integrated onchip graphics controller supports

4MB of SDRAM purpose of Display cache memory.

The Anaheim2A motherboard was designed to be highly minimized system cost. In this effort, a smaller form factor, Micro-ATX, gives the greater space economy and more affordable systems. Integrating onchip graphics controller and SDRAM, as well as AC’97 audio solution with AC97 Codec onto the motherboard eliminates the need for more expensive graphic and audio add-in cards. The end result is a system platform with a primary component level of integration with translates into affordable solution for entry level users.

2-6. Advanced Configuration and Power Interface (ACPI)

The motherboard and system BIOS support the ACPI that requires an ACPI-aware operating system such as

Windows-NT 5.0 or Windows 98 SE. ACPI feature include

• Plug and play and APM functionality normally contained in the BIOS

• Power management control of individual devices : add-in cards, hard disk drives, USB devices, and

Video

•

•

A soft-off feature that enables operating system to power off the computer

Support for multiple wakeup events

• Indication LED for normal mode (Green), standby mode (Blinking Green), and suspend mode (Blinking

Green) but this function is dependent on the LED logic.
