Simultaneous DMA

The manual for Interactive Unix states that it is possible for some DMA chips
to malfunction when more than one allocated DMA channel is used simultaneously.
Is there any way to tell whether a motherboard has this defect? One of the
boards in my system which uses DMA is the SCSI disk controller, so I'd rather
not test this under Unix and risk losing my filesystem. Even a DOS program
to test for this problem would be fine.
My motherboard is the AMI Voyager 486-25.
Thanks,
Brian
