DMA transfer mode selected

Hi all

We are still thinking about our problem with two cards PXI-6070E. We are
using REDHAT9+ADEOS+RTAI-24.1.12+kernel 2.4.22.

When we use high sample rate in both cards (1Ms/s) one of them stop
adquaring. We think the problem is the high number of interrupts in the
system. So we have some questions.

Which is the DMA transfer mode selected in comedi? Normal, Continue,
Ring Buffer, Link Chaining?

Is it possible to change the size of the DMA data block transfer?

Thank you again.
