Note:
The address locations of the PCI devices, such as SCSI or Ethernet, are not
described in the following tables, because the system BIOS automatically
configures (PnP, Plug and Play) all PCI devices.
Standard Register Set
The standard register set is equal to all standard PC/AT systems. The table
below provides an overview of the address ranges occupied by these registers.
