HARDWARE CONFIGURATION
This Mendocino® PPGA processor motherboard is based on the Intel®
82440EX/LX chipset. The chipset is a highly integrated solution for a cost-effective
motherboard and desktop design for the Mendocino PPGA processor. The
motherboard supports 3.3V EDO DRAM or Synchronous DRAM. The Features
on-board include super-I/O, Ultra DMA33 / PCI bus master IDE, PCI Ver 2.1
compliant, USB, VRM 8.2 compliant, ECC(440LX ver only), Micro ATX specification
1.0 compliant, hardware monitoring (optional), On-board Sound Sub-system (optional).
