NEC MH4500 manual change the server configuration resource settings

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)

modify the server’s boot device order or security settings

change the server configuration resource settings

save the server configuration

view or clear the system event log

Tview field replaceable unit (FRU) information view the sensor data record (SDR) table.

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 file (.CFG) supplied by the peripheral device manufacturer.

The I/O system board includes .CFG 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 .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.

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.
