I. Introduction
The Anaheim2 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 Anaheim2 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.
