I'm considering setting up some 386 UNIX systems each with a SCSI disk as the primary (and only) mass storage. (It is not yet decided which UNIX we'll be using.) Are there any horror stories out there about this? Should I forget it and go with IDE? Reply to me, and I'll summarize if there's any interest. --richard

Interactive Unix works well for us using this configuration. No horror stories. David Sears EssnJay Systems, Inc. Huntington, CT

We are going through this exercise right now. It appears that the motherboard/BIOS makes a big difference. Our 33Mhz caching Taiwanese mother board would not boot Interactive UNIX 2.2 using the Adaptec AHA-1542B SCSI Host Adaptor with a Micropolis 1684-7 disk drive(330Mb). We placed the SCSI HA/Disk into a 25Mhz unit, UNIX boots/installs just fine. The 25Mhz motherboard is from the same manufacturer. The whole system is sold under the SPEEDPRO name here in Switzerland. Our only problem is that the 25Mhz unit has been discontinued by the local dealer, so if the board blows we will have to find the same unit elsewhere or switch motherboards. The BIOS in the 25Mhz and 33Mhz unit is made by AMI, I believe the version in the 33Mhz unit is a later release even though both chip sets have the same stickers attached. If anybody knows the real reason for our problems please mail me direct. I did try some different jumper configurations on the Adaptec HA without success in the 33Mhz unit. -- James R.

Have you tried swapping the BIOS ROMS? Are both mother boards set up the same (buss speeds, IO wait states, etc) What is the ISC release? The new release (2.21) corrects some problems with lockups on fast machines - but I don't know if it addresses any problems with non-boots. -- Larry Snyder, NSTAR Public Access Unix 219-289-0282 (HST/PEP/V.32/v.42bis) regional UUCP mapping coordinator {larry@nstar.rn.com, ..!uunet!nstar!larry, larry%nstar@iuvax.cs.indiana.edu}
