Intereaction between Win 95 Registry and Iomega Zip Drive

I have a Dell Latittude Pentium 166 MMX with Windows 95. It has two configurations, one with the port replicator and one without.  Without, it starts fine.  Docked onn the port replicator, the windows banner displays, the screen goes out and an hour glass cursor appears.  It will remain this way for several minutes (3-5 before starting).  After some thrashing about I discovered that with the zip drive running, it would start normally.  Based on some previous answers to a floppy drive issue I had here, I have removed all the *.lnk and *.qip files on C: that refer to F: (the zip drive).  This has not cured the problem.

I had picked up a copy of the Norton Utilities and looked at the register for orphans as suggested in Norton.  I found over 200.  When I removed them all, I found that the system started normally but was messed up in other ways.  Since I was in over my head, I did a restore on the registry so the problem is back, but at least the rest of it works.

How do I go about identifying and removing the offending orphans without messing up everything else?
