Mainboard Form-Factor
The board is designed with an ATX form factor. The ATX form factor is essen-
tially a Baby-AT baseboard rotated 90 degrees within the chassis enclosure and a
new mounting configuration for the power supply. With these changes the proces-
sor is relocated away from the expansion slots, allowing them to hold full length
add-in cards. The ATX form factor provides a double-height aperture at the rear of
the chassis which can be used to host a wide range of onboard I/O devices,
enabling PC manufacturers to add new I/O features (for example, TV input, TV
output, joystick, modem, and LAN ). Other advantages include:
 Smaller form factor promotes an overall smaller system size.
 I/O shield does not need to be retooled in an ATX 2.01 form factor or later.
This 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 cost.
