To get a clue if the adapter will function properly at the DMA you set, run the bus master test at g=dc00:9. This test uses the current setting of the DMA transfer rate to test with. If it fails, back the DMA rate down. Roy Neese Adaptec Senior SCSI Applications Engineer UUCP @ uunet!utacfd!cs.utexas.edu! {nominil,merch,cpe}!adaptex!neese uunet!mlite!adaptex!neese
