Conflicting DMA Channels
DMA channel conflicts can usually be resolved by changing DMA
jumper modules on the applicable adapter. If the conflict is not
resolved, one of the conflicting adapters must be deleted from your
system.
Refer to the Interrupt and DMA Usage Chart on page 1-21 and 1-22
to plan your system configuration.
Determining Adapter Conflicts
The charts on this and the facing page shows interrupt levels and
DMA channels used by various adapters.
Make a list of all the adapters you intend to use in one machine. To
the right of the adapter list create two columns, one for interrupt
level and one for DMA channel.
If any DMA channel appears twice, a conflict exists and must be
resolved using the methods in “ Conflicting DMA Channels.”
If an interrupt level appears twice or more, determine whether the
conflicting adapters have changeable or shareable interrupt levels.
Then refer to “Conflicting Interrupt Levels” on page 1-19 and to the
installation text for the conflicting adapters.
