The following instructions will show you how to use the Windows 95/98 Device Manager to determine what resources your system has available. These available resources will then be used to set "jumpers" (small plastic covers inserted over pins) that configure the cards for your individual system. Under ideal conditions, three resources need to be configured (although the cards can be installed with as little as an I/O address only).

1. Right click on My Computer
2. Left click on Properties
3. Left click on the Device Manager tab
4. Double click on Computer
5. This brings up a window titled Computer Properties, like this:

In this example, IRQ 5 is available(because it is not listed)

When first opened, the Interrupt request (IRQ) list is displayed.
Look down this list and see if an IRQ is available. (If it is available, the IRQ is not listed).
The WarpExpress can use IRQ's 05, 07, 10, 11, 12 or 15. The F/PortPlus and the 1284Port can use IRQ's 05, 07, 12 or 15. Write down the IRQ that is available.

Next select the button Direct Memory access (DMA).
Look down the list and see if 01 or 03 is available (once again, if it’s not listed, it is available). Write the available setting down.

Next select the Input/output (I/O) button.
Look down this long list and see if 0278 is listed. If 0278 is in use, next look for 0378. Note: In most cases 0378 is your original built-in port and 0278 will be available.
If necessary, the WarpExpress card can also use two additional addresses:  0288 or 0388. When choosing a I/O address for the WarpExpress, choose the first address that is available, in this order: 0278, 0378, 0288 and 0388.  Write down the available setting.

With the three settings that you have written down, you are now ready to jumper the card.

You will notice that our cards have the settings silk-screened right onto the circuit board itself. When you jumper the card to a setting, you are covering up pins on the card. For example to choose IRQ 10, you would be covering the two pins that are marked "10" with the plastic jumper. It takes two plastic jumpers to make the DMA and I/O address selection.

Once your card is properly configured, you are ready to install the card.
