HARDWARE CONFIGURATION
The Pentium® II motherboard is based on the Intel® 82440LX Chipset. The
chipset is a highly integrated solution for a cost-effective and compact
motherboard. The motherboard supports 3.3V EDO and SDRAM. Features
on-board include super-I/O, Ultra DMA33, PCI bus master IDE, AGP Ver 1.0,
PCI Ver 2.1 compliant, USB, VRM 8.1 compliant, ECC, LM79/75 System
monitoring (optional).
Key Features
Processor
•
Full support for the Intel
®
Pentium II processors using Slot 1connector.

operating from 200MHz to 333MHz.
VRM (Voltage Regulator Modules) on Board
•
Flexible motherboard design with on-board VRM 8.1, easy to upgrade
with Intel’s future overdrive processors.
Cache
Processor built-in L2 cache (Tag RAM and 2 or 4 BSRAMs for 256KB or
512K).
