Functional Architecture Intel® Server Boards SE7320SP2 and SE7525GP2 3.7.2 I/O Map The server board I/O addresses to be mapped to the processor bus or through designated bridges in a multi-bridge system. Other PCI devices, including the Intel® 6300ESB I/O controller, have built-in features that support PC-compatible I/O devices and functions, which are mapped to specific addresses in I/O space. On SE7320SP2 and SE7525GP2, the Intel 6300ESB I/O controller provides the bridge to ISA functions. The I/O map in the following table shows the location in I/O space of all direct I/O-accessible registers. PCI configuration space registers for each device control mapping in I/O and memory spaces, and other features that may affect the global I/O map.
