Introduction
The Classic/PCI i486 Baby-AT Motherboard delivers excellent, cost effective performance in a very affordable i486
platform. A wide range of CPU offerings provides immediate performance flexibility, and a single 238-pin blue
OverDrive Ready ZIF (Zero Insertion Force) processor socket allows upgrades to higher performance in the future.
Additionally, by incorporating a second level, high performance cache and four SIMM sites for memory expansion to 128
MB, five ISA expansion connectors and three PCI connectors, the Classic/PCI i486 Baby-AT Motherboard is ideally
featured for expandable, performance sensitive desktop applications. The Classic/PCI i486 Baby-AT Motherboard will
excel in high end i486 Processor desktop PCs running existing compatible applications.
An easy upgrade path to higher CPU performance is built into the Classic/PCI i486 Baby-AT Motherboard. The processor
socket accepts either an i487SX to enhance performance with numeric intensive applications, or an OverDrive
Processor, Intel's upgrade component that doubles the speed of all i486 internal processes. Support for the next generation
OverDrive Processor, based on the Pentium CPU, protects today's investment in the Classic/PCI i486 Baby-AT
Motherboard.
The mini-Baby-AT board with i486 CPU, cache, and integrated I/O is the smallest PCI-based motherboard solution
on the market today that is upgrade able to an OverDrive processor based on Pentium CPU technology.
BABY-AT FORM FACTOR
The Classic/PCI i486 Baby-AT motherboard matches the Baby-AT standards well established in the PC industry, while
reducing the size from the full length (13") form factor. This Baby-AT industry standard specifies the maximum board
size, board mounting locations, and location for the keyboard connector, as well as expansion slot placement. The
Classic/PCI i486 Baby-AT meets all of these requirements while adding PCI expansion possibilities. Figure 1 illustrates
the Baby-AT form factor. A list of several chassis suppliers supporting the Baby-AT standard is included in Appendix
I.
