switches on the card itself. When you can, you should use PCI cards instead of ISA
ones.
Your computer has a PCI configuration utility that automatically sets up a newly-
installed PCI card to work with your computer and other PCI cards. However, if you
install a new PCI card, it could conflict with the existing configuration so much that you
cannot start the computer. If this happens, reset the configuration data using Setup as
described below.
When you install ISA cards, you need to configure these in two ways: set jumpers or
switches on the card before you install it, and use Setup to reserve resources such as
interrupts and memory addresses. Refer to the ISA card manual for more details on
what resources are used by the card, and refer to page 61 for more details on using
Setup.
The system is designed to provide an average of 1.5A (amps) of +5 V power for each
card in the system. The total +5 V current-draw in a fully loaded system (all add-in card
slots filled) must not exceed 7.5A.
When a card is installed, you can access the external connectors on it via an opening in
the back of the computer. When no card is installed in a slot, the opening is closed by a
cover. If you remove or move a card, it is important that you use the covers to close the
opening to ensure correct electromagnetic shielding and to ensure proper cooling.
