My main problem was that the de-virused and damaged system was 7.5.5 and although I had upgrade floppy disks from version 7.3.1 to 7.5.5 the machine would not accept them - presumably because the disks themselves were 7.3.1. Because the machine stores the current version of the OS in non-volatile memory it is only possible to upgrade the OS to a higher version. In my case 7.6.1 or 8.0.0. The user decided it would be quite nice to try out version 8 so that I have upgraded their Mac to 8.0.0. The upgrade was flawless and their applications, documents and data are still in tact. I was quite impressed with the new OS and relieved I didn't have to back-up the 1 gig and do a raw install. Come to think of it - given my comments above - how would I have re-initialised the drive to version 7.3.1 so that I could then upgrade back to 7.5.5 ? The user has now invested in more efficient anti-virus software and promised to back-up their system in a proper manner. Cheers, -- Dave Besnard
