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.
