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:

nAdd and remove ISA Legacy boards affecting the assignment of resources (ports, memory, IRQs, DMA)

nChange the server configuration resource settings

nSave the server configuration

nView 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.
