I. Introduction
The Florida-TG Micro ATX motherboard offers a time to market consumer and corporate desktop
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 motherboard was designed to be highly minimized system cost. In this effort a smaller
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.

2. Upgradeability
2-1. Processor
FLORIDA-TG motherboard provides the 370pin PGA370 socket that is not backward compatible with ZIF
socket-7 processors The Processor’s VID pin automatically program the voltage regulator on the motherboard
to the required processor voltage. The motherboard supports processors that run internally at
300/333/366/400 MHz.
TSupported Intel Celeron Processors (PPGA Socket Type)
•Intel : Celeron 300MHz

Note 1.
Also AGP graphics controller does not use any PCI interrupt in the Florida-TG(A) motherboard, because
the interrupt function of AGP graphics controller was designed to disabled status. For more information,
please contact the technical support team.
2-5. Advanced Configuration and Power Interface (ACPI)

•Power management control of individual devices : add-in cards, hard disk drives, USB devices, and
Video
•A soft-off feature that enables operating system to power off the computer
•Support for multiple wakeup events
•Indication LED for normal mode (Green), standby mode (Blinking Green), and suspend mode (Blinking
Green) but this function is dependent on the LED logic.
