The machine I am setting up to test changes in the ncr-risc code for the scsi controllers also has the Cobra EISA BA. Will look at the EISA DMA situation, but it will be a matter of luck not skill or knowledge if I can make it work. I do recall that getting the contents of the cache and the memory to be the same has to be done in software and it did not sound easy the first time I read about it.
