Memory/Expansion Connectors; Pci/Isa Riser Connector (J6J2) - Intel AP440FX Technical Product Specification

1.12.2 Memory/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.
