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.
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.
