I. Introduction
The
Florida-TG
solution featuring the Intel Celeron PPGA processor with 66MHz front side bus and the Intel 440LX AGP sets in a
Micro ATX low profile motherboards. In addition, the integrated graphics components have been upgraded with the
AGP graphics controller and 4 or 8MB of SGRAM.
The
Florida-TG
form factor, Micro-ATX, gives the greater space economy and more affordable systems. Integrating AGP graphics
controller and SGRAM, as well as PCI audio solution with AC97 Codec onto the motherboard eliminates the need
for more expensive graphic and audio add-in cards. The end result is a system platform with a primary component
level of integration with translates into affordable solution for entry level users.
