The Micropolis 4110 you are using is a very fast & agressive driver of the SCSI bus, so you should check your SCSI termination and make sure that you are using active termination at both ends, and that your cables and connectors are all up to snuff. You should also make sure that you don't have too much termination on the bus (ie. the 4110 and the SCSI controller should be at the ends of the bus, and the CDROM should be between them with its termination OFF). Also make sure that you have SCSI parity enabled on all of the devices. > my guess it may be related to disk geometry, but i do not know what > disk geometry should be used. during novice installation, disk geometry > shown as: 1002 cyl/64hd/32sect. > When i checked micropolis web site, for hp workstation the disktab > shown 1052 MB 512 bytes/secto, 5400 rpm, ns=93, nt=9, nc=1226 > and for SUN workstation, ncyl=1998,nhead=9,nsect=114. > is the problem above due to disk geometry? No, the above problem would not be caused by incorrect disk geometry. You have a hardware problem somewhere, most likely in the SCSI chain, although I wouldn't rule out the possibility of a bad SIMM. -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] "wherever you go, there you are" - Buckaroo Banzai [[
