Code 24: The GPIB interface is not installed, or it is not configured
to match the resources assigned to it. Either install the GPIB
interface, or verify that the resources assigned to it on the
Resources page match its settings.

Code 27: Windows was unable to assign the GPIB interface any
resources. To solve this problem, free up system resources by
disabling other unnecessary hardware so that enough resources are
available for the GPIB interface.

If you have previously installed the Compatibility Release for
Windows 98/95, you should remove any system-reserved resources for

complete the following steps:

Select Start»Settings»Control Panel.
2.
Run the System Properties applet by double-clicking on the
System icon.
3.
In the System Properties dialog box that appears, select the
Device Manager tab.
4.
Click on the View devices by type button at the top of the
Device Manager page.
5.
Double-click on the Computer icon.
6.
In the Computer Properties dialog box that appears, click on the
Reserve Resources tab.
7.
Remove the Interrupt request (IRQ), Input/output (I/O), and
Direct memory access (DMA) resources that you reserved for the
AT-GPIB/TNT.
