2.2.1.1 ATX Form Factor for Slot-1 System
A proposed component placement and signal group routing for an Apollo Pro133A ATX form factor system design is illustrated in
Figure 2-3. The major components on the board are single Slot-1 CPU, five PCI slots, one AMR, one ISA slot and three DIMM
slots. This figure shows an ATX motherboard placement as a reference only. The placement should be re-evaluated if a different
combination of AGP, PCI and ISA slots and other motherboard peripherals is desired.
