INTRODUCTION
The 694D PRO (MS-6321) ATX mainboard is a high-performance
computer mainboard based on VIA
®
VT82C694X chipset. The 694D PRO is
designed for Intel
®
Pentium
®
III (FC-PGA) processor for cost-effective
business/personal desktop markets.
The Apollo Pro133A (VT82C694X) is a Socket-370 system logic
north bridge with the addition of 133 MHz capability for both the CPU and
SDRAM interfaces. Apollo Pro133A may be used to implement both desktop
and notebook personal computer systems from 66MHz to 133MHz based on
Socket-370 (Pentium
®
III processor). The primary features of the Apollo
Pro133A-North Bridge are: Slot-1 or Socket-370 CPU (Front Side Bus)
Interface (66 / 100 / 133MHz), DRAM Memory Interface (66 / 100 / 133MHz),
AGP Bus Interface (66MHz), PCI Bus Interface (33MHz), Mobile Power
Management.
The VT82C686A PSIPC (PCI Super-I/O Integrated Peripheral
Controller) is a high integration, high performance, power-efficient, and high
compatibility device that supports Intel and non-Intel based processor to
PCI bus bridge functionality to make a complete Microsoft PC99-compliant
PCI/ISA system.
