This MacOS 8.1 CD (I do not have a 8.0 CD) gives me the options to install a full clean install of MacOS 8.1 or upgrade. I chose the clean install. Then a customized install selecting only the "Mac OS 8.1" option (no Java, internet access, text-to-speach, etc). It gives med no further customize options unlike my MacOS7.6 or MacOS9 install where I had another option for universal install, this mac, and some other third option.
It could be that my media is for a specific Mac? I will need to get back to work to have a closer look at the CD. I might need a different MacOS8 media. A MacOS8.0 version and install the 8.1 upgrade from there.
Edit: Changing the CPU option in E-UAE changed the behavior of the install of MacOS. I'll examine it closer.
Edit: I did get the A/ROSE startup error this time and removed the extension, but still crashes when loading the Finder.
It could well be that your media is specific to a model or series of models of Mac, that would be my best guess. I'm not sure about the 8.1 media, I only had the 8.0 that came with an old powermac7220, and I later downloaded the 8.1 update off the Apple site.
its possible that the emulator NEEDS some extensions to run, whilst others cause it to crash. If you disable all extensions on boot up, you might be disabling necessary as well as conflicting ones. It might be a process of elimination to find the right mix. The other thing that used to cause problems was cfm-68k runtime enabler-sometimes I needed installed, sometimes disabled.
AFAIR most of the additions that came with 8.1 applied to powermacs, and the only noticeable thing was that it was slower than 8.0.
