Processor

Anaheim2A motherboard provides the 370pin PGA370 socket that is not backward compatible with ZIF
socket-7 processors The Processor's VID pins automatically program the voltage regulator on the
motherboard to the required processor voltage. The motherboard supports processors that run internally at
300/333/366/400 /433/466/500/533MHz.
Supported Intel Celeron Processors (PPGA Socket Type)
•
Host Clock 66MHz
•
Host Clock 100MHz
Supported Cyrix Goby Processors (PPGA Socket Type)
•
Host Clock 66MHz
2-2. Main Chipset Configuration
Anaheim2A Motherboard has two main chipset configurations.
810DC100 Configuration
• GMCH + ICH
810L Configuration
• GMCH0 + ICH

Memory

The motherboard has two, dual inline memory module (DIMM), minimum 16MB to maximum 256MB memory
size. The BIOS can automatically detect the memory type, size, and speed through SMBUS interface between
the core chipset and DIMM module.
The motherboard supports the following memory features
•
3.3V and unbuffered168-pin DIMM
Voltage detection
Unbuffered detection
•
100MHz unbuffered SDRAM (PC100)
•
Non-ECC memory only
•
Single or double-sided DIMM with the following types (per each side of each DIMM)
