B-2 System Setup Utility
System Setup Utility (SSU)
The System Setup Utility (SSU) is a DOS-based utility that supports extended system
configuration operations for onboard resources and add-in boards. It also allows you to
view the system event log and to set system boot and security options. Use the SSU when
you need to:
n Add and remove ISA Legacy boards affecting the assignment of resources (ports,
memory, IRQs, DMA)
n Change the server configuration resource settings
n Save the server configuration
n View or clear the system event log.
If you install or remove an ISA Legacy add-in board, you must run the SSU to reconfigure
the server. Running the SSU is optional for a PCI add-in board.
The SSU is PCI-aware, and it complies with the ISA Plug and Play specifications. The SSU
works with any compliant configuration (.CFG) or overlay (.OVL) file supplied by the
peripheral device manufacturer.
The I/O baseboard includes .CFG and .OVL files. The .CFG file describes the
characteristics of the board and the system resources that it requires. The configuration
registers on PCI and ISA Plug and Play add-in boards contain the same type of
information that is in a .CFG file. Some ISA boards also include a .CFG file.
The SSU uses the information provided by the .OVL and .CFG files, configuration
registers, NVRAM, and the information that you enter, to specify a system configuration.
The SSU writes the configuration information to NVRAM memory.
The SSU stores configuration values in NVRAM memory. These values take effect when
you boot the server. POST checks the values against the actual hardware configuration; if
they do not agree, POST generates an error message. You must then run the SSU to specify
the correct configuration before the server boots up.
