Okay- I'm not a Unix techie, but as far as the ISC's driver
goes I thought the DMA rate paramter was ignored (and if it's not,
has anyone fooled around with tuning it higher?).  This is for
the adaptec scsi board, remember.

It could be I'm thinking of ISC's generic tape driver.  I'm pretty
sure any default DMA rate there, is ignored.

Thanks,
Evan
