Various hardware settings on the adapter, such as the ring speed and DMA channel, can be set with switches on the adapter or using a configuration utility supplied on the MDGBOOT diskette shipped with your Ringnode. Refer to the documentation supplied with the Ringnode for detailed instructions.
When choosing hardware settings:
Ensure that your Ringnode does not use the same IRQ as other adapters in your PC--and for AT Ringnodes, not the same DMA channel and I/O address.
Make sure the selected ring speed matches that of the ring you want to connect to.
Note that a configuration utility must almost always be used to select features of the adapter (for example, ring speed). If the adapter isn't functioning properly, try alternate features, such as PIO instead of DMA, different I/O addresses, and so on.
