The ISA bus has only 24 address lines which limit addressability to 16 Mb. I you intend to use more than 16 Mb of memory go to either EISA or Micro-channel which utilize a 32 bit buss and can therefore access 4 Gb. > Q2. What's the difference between the 1542B and C? > > The 1542C is jumperless and is software configurable. > Q3. If I plan to stay within the DOS / Windows environment would > the faster Procom adapter be the best choice? > I don't know how much of a performance difference there is between the two adapters but both OS/2 2.x and Windows NT build in support for Adaptec SCSI adapters. You may feel today that you will stay with DOS/WIndows but might change your mind after you see OS/2 2.1. > > > Q4. Will I be able to hook up other SCSI based devices (eg.

Hope this helps. .. Ron 24-Apr-93 22:07
