Overview; Resource Configuration Utility (Rcu); Using The Rcu - NEC MC2200 User Manual

Overview

Configuration and setup utilities are used to change your system configuration. You can
configure your system, as well as option boards you may add to your system, using the
Resource Configuration Utility (RCU) diskette. Also, several unique system parameters
are configured using BIOS Setup which is stored in the system FLASH memory. A
diskette is not needed to run BIOS Setup.
A Utilities diskette contains the SCSISelect Utility and the Event Log Utility. The
Event Log Utility is used to read stored system event information. The SCSISelect
Utility is used if you need to configure the SCSI controller in your system or to perform
a SCSI disk format or verify disk operation of these drives.
If your system has been factory configured, the RCU, BIOS Setup, or SCSISelect
utilities do not need to be run unless you want to change the password or security
features, add option boards or devices, or upgrade your system board.
There are some system configuration parameters that are set by jumpers on the system
board. However, these parameters do not usually require change.
This chapter provides procedures for running the RCU, BIOS Setup, and the Utilities
diskette. Several configuration tables are provided in this chapter to record changes you
make to the default system configuration.
You use the EXPRESSBUILDER CD-ROM to create the RCU and Utilities diskettes.

Resource Configuration Utility (RCU)

The Resource Configuration Utility is used to configure your system. The RCU can be
used to configure the memory subsystem, peripheral device subsystems, and interface
adapters. RCU recognizes ISA Plug-and-Play boards and PCI boards and displays their
configuration. ISA (non-Plug and Play) adapter boards must be added to the RCU
configuration to reserve the resources required by the ISA boards.
After you add options using the RCU, the system automatically configures and
initializes them during system initialization at boot up.
The RCU stores the configuration information in the non-volatile memory on your
system. When you exit the RCU the configuration information is written to non-volatile
memory. The RCU also maintains the Setup configuration, which is stored in the
battery-backed memory. This means that when you exit the RCU, the Setup and RCU
configuration will agree with each other.

Using the RCU

If you are adding a non-Plug and Play ISA option board, run the RCU before installing
the board using procedures found in Chapter 4, Upgrading Your System. If you are
upgrading system memory, do so before running the RCU using procedures found in
the Chapter 4 of this guide. To use the RCU:
Always save the current settings before reconfiguring the system.

Note: The system can fail following improper configuration.
