The System Configuration Utility uses option configuration (.CFG) files to set
up and configure the computer. The .CFG files provide information such as
switch settings, IRQs, and software installation guidelines. The .CFG files for
Compaq computers are located on the System Configuration diskettes and
SmartStart CD.
For PCI boards, the utility reads the configuration options from the PCI
board's configuration space and optionally from a PCI configuration file
(.PCF).

The .CFG file provides board resource requirements and switch and jumper
setting alternatives. Although ISA boards do not have the automatic
configuration capabilities of PCI boards, the System Configuration Utility can
allocate system resources to these boards and provide instructions for setting
switches and jumpers.
Resolving Resource Conflicts
If you add a PCI expansion board later, the system discovers this change when
you turn on the computer. The system ROM reads the PCI board identifier and
compares it with the current configuration information stored in nonvolatile
memory. The system ROM automatically configures PCI boards. If a user
selection is required, a POST message directs you to run the System
Configuration Utility. Additionally, you may change the default automatic
settings by running the System Configuration Utility.
