Resolving resource conflicts
Using Setup
Your computer's Basic Input/Output System (BIOS) automatically detects most
hardware changes and then updates the related CMOS configuration settings in
Setup. In cases when the CMOS settings are not automatically updated, you
receive a message reminding you to manually update the settings.
To resolve resource conflicts between system devices in Setup, follow these steps:
1. Enter Setup. See “Entering Setup” on page 6-4 for instructions.
2. From the Configuration/Setup Utility menu, select
PnP/PCI Option
.
3. Highlight the
Reset configuration Data
parameter and set it to
Enabled
to
clear the resource assignments of all installed cards.
After the above steps, proceed to the next section on how to use the Windows 98
Device Manager to assign system resources to your hardware devices.
