I havew a 8600/ 366 G3 and I was able to install 9.2.1 but then my DSL software
crashed the computer when I tried to start it, so I reverted back to 9.1. This weekend
when I have time, I may try this way, install a clean 9.1 then do a 9.2.1 and try to
install everythign from scratch with the DSL software first to see if I can get it to
work that way.
