The SSU is PCI-aware and complies with the ISA Plug and Play specification; it works with any compliant configuration (.CFG) files supplied by the peripheral device manufacturer.

The system board comes with a .CFG file describing the characteristics of the board and the system resources it requires. The configuration registers on PCI and ISA Plug and Play expansion cards contain the same type of information in a .CFG file. Some ISA boards also come with a .CFG file.

The SSU uses the information provided by .CFG files, configuration registers, flash memory, and the information that you enter, to specify a system configuration. The SSU then writes the configuration information to flash memory.

The configuration values in flash memory take effect when you boot the server. POST checks the values against the actual hardware configuration; if the values do not agree, POST generates an error message. You must then run the SSU to specify the correct configuration before the server boots.

The SSU always includes a checksum with the configuration data so the BIOS can detect any potential data corruption before the actual hardware configuration takes place.

What You Need to Do

You must run the SSU from a set of DOS diskettes. You must follow the instructions in the included README.TXT file to prepare the diskettes.

If your diskette drive is disabled or improperly configured, you must use the flash-resident Setup utility to enable it so you can use the SSU. If necessary, disable the drive after exiting the SSU. Information entered using the SSU overrides any entered using Setup.
