Make sure you have a slot available for the type of card you are installing. Also check
the Windows 95 Device Manager or Windows NT Diagnostics for an available inter-
rupt request (IRQ) that is supported by the card.
To check Windows 95 resources, follow these steps:

To check Windows NT resources, start the Windows NT Diagnostics in the Adminis-
trative Tools (Common) folder and view the Resources tab.
NOTE: If an IRQ supported by your card is not available, it may be possible to reassign
resources used by other devices or disable unused devices.
The computer can support a mixture of traditional ISA expansion cards (called legacy
expansion cards), Plug and Play ISA expansion cards, and PCI expansion cards. The
system basic input/output system (BIOS) allows you to install both PCI and ISA Plug
and Play expansion cards without performing manual configuration tasks.
NOTE: If you are using the Windows NT operating system, you should configure ISA
expansion cards manually. If you do not have a manually configurable card, you can
use the ISA Configuration Utility (ICU) to manage ISA expansion cards. This utility can
be downloaded from the Dell World Wide Web site at http://www.dell.com/.

Check the documentation to make sure the card is configured to work with other
devices already installed in your computer. Set any necessary jumpers or
switches on the card to avoid conflicts with devices already installed.
