Resolving Resource Conflicts with Legacy Boards
Resource conflicts typically occur when your system contains legacy
boards that use resources that have not been reserved properly with the
Device Manager. If a resource conflict exists, write down the resource that
caused the conflict and refer to the Microsoft Windows 98/95 user’s guide
for instructions on how to use the Device Manager to reserve I/O and IRQ
resources for legacy boards.

Start»Settings»Control Panel
