Motherboard Description

1.12.2Memory/Expansion Connectors

The AP440FX motherboard has four 72-pin SIMM sockets for main memory. These sockets accept standard SIMM 72-pin modules, as long as they satisfy the requirements described in the “Main System Memory” section of this specification, starting on page 12.

The AP440FX motherboard uses a PCI/ISA riser connector (J6J2) to provide for expansion PCI or ISA boards. The associated riser board can support either two or three PCI slots. A pair of jumpers on the AP440FX motherboard must be set to define the number of PCI slots on the riser board. Refer to Figure 8 on page 35 for jumper block details. Table 7 shows the pinout listing for the PCI/ISA riser connector.
