If you are providing a value for the interrupt request (IRQ) or direct memory
access (DMA) resource, click the down arrow beneath Available Resources. A
smaller Specify list box appears (see Figure 3-8). Click the value you want to
assign to the resource. Then click OK.
If none of the values for the DMA or IRQ resources match the allowable values
for your unlisted card (as indicated in the card's documentation), select one of the
available values offered by the utility and click OK.
If you are providing values for the input/output (I/O) port or memory resources,
you must enter the starting and ending addresses in hexadecimal format using
the two fields provided by the Specify Memory or Specify I/O Port dialog box (see
Figure 3-9). Click each box in succession to enter the beginning and ending
addresses, and then click OK to complete the selection.
A message box appears, notifying you either that the card is using its default set-
tings or that it cannot use its default settings and must be reconfigured.
