ATX FORM-FACTOR
OVERVIEW
The PP6-NF
has been designed with ATX form-factor. The board size is 12" x 9.6"
(305mm x 244mm). The ATX from-factor improves over Baby AT and LPX in a
number of ways. By using the ATX chasis then the power supply orientation and
specification and rotating the Baby AT baseboard through 90 degrees, the pentium
Pro processor can be relocated away from the expansion slots, and the longer side of
Add-on card can be used to host more on board I/O. From Figure 3-1: Summary of
ATX chassis features layout the user can gain a great deal improved functionality.
