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.
