The EP-5ATXA-M is base on ATX form-factor with a board size 8.2" x 12" (208mm x
305mm). The ATX from-factor is essentially an enlarged baby-AT basedboard rotated
90 degrees within an ATX chassis and uses ATX power supply. The changes make
pentium processor able to locate away from the expansion slots and all onboard I/Os
able to hold full length add-on cards. The improved features of an ATX form-factor
from a baby-AT or LPX form-factor are shown as follows (see Figure 3-1).
