FR550
1 Introduction
1.1 Overview
The FR550 mainboard integrates the Pentium microprocessor, memory, and I/O technologies
and is designed to fit into a standard ATX form factor chassis. The design supports Pentium
processors, Pentium processors with MMX technology, Cyrix 6X86/6X86L/M2 Processors,
and AMD K5/K6 Processors. Page 2-2 illustrates the mechanical form factor for the FR550
mainboard.
The ATX was developed as an evolution of the Baby-AT form-factor and was defined to
address four major areas of improvement: enhanced ease-of-use, better support for current and
future I/O, better support for current and future processor technology, and reduced total
system cost. The processor is relocated away from the expansion slots, allowing them all to
hold full length add-in cards. The longer side of the board is used to host more on-board I/O.
Finally, by using a power supply that is specially optimized for ATX, it is possible to reduce
cooling costs and lower acoustical noise. An ATX power supply, which has a side venting,
allows direct cooling of the processor and add-in cards, making a secondary fan or active
heatsink unnecessary in most system applications.
