Configure the PC/104-GPIB DMA Channel
If Windows is unable to assign a DMA resource to the PC/104-GPIB, or if you are installing the
PC/104-GPIB in an 8-bit stack, you can configure DMA to none and still use the NI-488.2 software.
Change the jumper settings to match the DMA channel assigned to your board, or to no DMA if
you are installing the PC/104-GPIB in an 8-bit stack. You must set both the DMA Acknowledge and
DMA Request lines. By default, the PC/104-GPIB is configured to use DMA channel 5.
