I think it's dependent on your SCSI drives (if you have any as to what breaks). I have 32MB's in my EISA box, and I've had 64MB's in it, and there haven't been any problems, when using a 1740 EISA card. But apparently there is some kind of weirdness with ISA Adaptec's (154x) that have problems with DMA above 16MB's and then you get troubles. If you only have IDE or ESDI drives, I don't think there are any problems. I ran mine for a few days off an IDE drive while getting the SCSI stuff straightened out, and don't remember having any problems. -- Jaye Mathisen, COE Systems Manager (406) 994-4780 410 Roberts Hall,Dept. of Computer Science Montana State University,Bozeman MT 59717 osyjm@cs.montana.edu
