Resolving Hardware Conflicts
Hardware conflicts occur when two or more peripheral devices attempt to use the same hardware
resources. I/O addresses, interrupts, and DMA channels are the most common hardware resources
used by peripheral devices.
Base I/O address 220H
Interrupt IRQ 5
8-bit DMA Channel 1
When different peripheral devices use the same hardware resources at the same time, the devices
and/or the system may not function properly. You can resolve hardware conflicts by ensuring that no
devices are configured to use the same hardware resources. These resources can either be dipswitch
or jumper settings on the peripheral card or software configurable resources. The Computer Setup
selection of your Compaq Utilities allows you to view and modify the settings for the peripheral
devices factory installed in your system. Refer to the User's Guide for the particular peripheral cards
you wish to install for information on how to view and select their settings.
To resolve hardware conflicts:
1 Change the hardware settings of your audio card or other peripheral card in your
system if the peripheral card is using any settings used by the factory-installed
devices.
2 If you are unsure of the settings of the peripheral cards, you can isolate the
source of the problem by temporarily removing all cards not manufactured by
Compaq, or resetting the default settings and running Compaq Utilities. After
that, add the cards back one at a time until the card that is causing the conflict is
found.
