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:
!
Add and remove ISA Legacy boards affecting the assignment of
resources (ports, memory, IRQs, DMA)
!
Change the server configuration resource settings
!
Save the server configuration
!
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.
