Mainboard Form-Factor
The board is designed with Micro ATX form factor - the new industry standard of
chassis. Micro ATX form factor is essentially a Baby-AT baseboard rotated 90
degrees within the chassis enclosure and a new mounting configuration for the
power supply. With these changes the processor is relocated away from the
expansion slots, allowing them all to hold full length add-in cards. Micro ATX
defines a double height aperture to the rear of the chassis which can be used to
host a wide range of onboard I/O. Only the size and position of this aperture is
defined, allowing PC manufacturers to add new I/O features (e.g.; TV input, TV
output, joystick, modem, LAN, etc.) to systems. This will help systems integra-
tors differentiate their products in the marketplace, and better meet your needs.
• Smaller size promotes a smaller system size.
• I/O shield does not need to be retooled in an ATX 2.01 or later. The
mainboard should be used in an ATX 2.01 (or later) compliant case.
• A smaller power supply can be used. High integration on mainboard
reduces the system costs.
