Chapter 3 Configuring The System
When to Run the BIOS Setup Utility
The Setup utility lets you change the system configuration defaults. It does
not let you enter or change information about PCI or ISA add-in boards; you
must use the SCU instead. Setup stores most of the configuration values in
the battery-backed memory of the RTC; the rest of the values are stored in
flash memory. The values take effect when you boot the system. The POST
checks these values against the actual hardware configuration; if they do not
agree, it generates an error message. You must then run Setup to specify
the correct configuration.
You can run the Setup utility with or without an operating system being
present.
Since values entered using the Setup utility are overwritten when you run
the SCU, you should only run Setup under the following conditions:
• To enable the diskette drive
• If you do not have access to a diskette drive
• If you do no want to configure any ISA add-in boards in the system
Running the Setup Utility
