@DGB,
When I put in the OS3.9 CD AsimCDFS opens a player window "prefs" close it, There are 2 icons, OS3.9 & emergency-boot.
When OS3.9 is opened I get 6 icons, one is OS3.9. When this is opened I get 3 icons, 1 is "OS3.9 installation". When this is clicked I then get the picture with other selections, create emergency disk, install from 3.1, etc.
Do you get that far. I have an A2000, see profile.
Keep at it.
Chris
PS: I also purchased my copy from Softhut.
