If running four users on 2.5MB under UNIX counts as intensive, there's no problem. The results are the same with or without the cache, just a LOT slower without. I have run Xenix and V.3 on AMI, Dell, and Compaq without problems. I believe that there are some disk controllers which have problems with a cached M.B. under some conditions, but I've never seen it with WD, Adaptek, or Perstor. -- bill davidsen - sysop *IX BBS and Public Access UNIX davidsen@sixhub.uucp ...!uunet!crdgw1!sixhub!davidsen "Getting old is bad, but it beats the hell out of the alternative" -anon
