I'd heard rumours that someone had three disks running off an IDE controller, but I can't recall how they were doing it 8( > The secondary reason for this question is that I am going to recommend that our > company buys a PC to run FreeBSD as the network/file/name/news/mail server. > This would free a bit of load from the development machine that is curently > doing this as well.

IDE is, in general, a very poor choice for any sort of serious system; you will be much better off going for a SCSI solution; and yes, being able to hang a DAT off the box is one good reason for doing it. > John Richards * email : john@zyqad.co.uk -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] My car has "demand start" - Terry Lambert [[
