Understanding and Resolving Hardware Conflicts

Windows, together with its Plug and Play technology, has grown far better at detecting and preventing hardware conflicts over the past few years. Still, system conflicts do arise, especially when you're using old ISA cards and other legacy hardware. (We suspect that there is little of this equipment still in use and look forward to the day that we can delete this section from some future edition of this book. Until that day comes, we're stuck with it.)

More often than not, configuration and installation problems are due to incorrect settings on an ISA network, I/O, sound, modem, and SCSI cards. The result is cards that conflict with one another for the same IRQ (interrupt request line), base I/O port address, DMA, or base memory address. Usually, these settings are made by changing jumpers or DIP switches on the board.
