Configuring Your System
System Configuration Utility (SCU)
The System Configuration Utility is used to configure
your system. The SCU can be used to configure the
memory subsystem, peripheral device subsystems, and
interface adapters. SCU recognizes ISA Plug-and-Play
boards and PCI boards and displays their
configuration. SCU also recognizes EISA boards so they
can be configured using the configuration diskettes
supplied with these boards. ISA (non-Plug and Play)
adapter boards must be added to the SCU configuration
to reserve the resources required by the ISA boards.
After you add options using the SCU, the system
automatically configures and initializes them during
system initialization at boot up.
The SCU must be executed every time ISA or EISA
adapter boards are added, removed or relocated in the
system.
T
The SCU stores the configuration information in the
non-volatile memory on your system. When you exit the
SCU the configuration information is written to non-
volatile memory. The SCU also maintains the Setup
configuration, which is stored in the battery-backed
memory. This means that when you exit the SCU, the
Setup and SCU configuration will agree with each
other.
