Installing Upgrades on the System Board 2-11
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 reas sign
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 oth er
devices already installed in your computer. Set any necessar y jumpers or
switches on the card to avoid conflicts with devices already insta lled.

ing, so only one of these connectors can be used.
