ShapeShifter and MacOS8

[stefcep2]

I did get 8.1 to work on a 68060 Cyberstorm 2 A4000.  There is something in 8.1 which conflicts with 68060.  Unfortunately I don't remember what.  BUT 8.1 is MUCH slower than 8.0 and I couldn't see the benefits over 8.0  Sorry not much help I know, but it was such a long time ago.  It does work though.

Yes you need a "general" version of the OS installed, not a specific model one.  And the ROM matters as well.

I just remembered.  There is a something called "Rose" in 8.1 that you have to remove.  It might be an extension.  So if you can boot into 8.1 using shapeshifter under euae, then have a look for anything with "rose" in the name and remove it.

Re: 68060 superscalar.  I think you have to boot your amiga with that switch as the first line in startup-sequence.

try to install Oxypatcher!!
should works with this one

i don't think oxypatcher matters matters. AFAIR the superscalar switch was needed beacsue Apple never had 68060 support in any of its OS's, beacsue it went form 68040 to ppc.

Been trying a little more to get MacOS 8.1 to work.

Putting "cpu060 NOSUPERSCALAR" at the beginning of startup-sequence didn't help.

Regarding "rose" do you mean "A/ROSE" as in http://en.wikipedia.org/wiki/A/ROSE ? I couldn't find any files with "rose" nor "prep" in the installation. I tried installing MacOS 8.1 again using custom install to see if I could see any reference to "rose", but I didn't. It may be labeled as something else?

Yes.  I found this: http://hemmerling.free.fr/html/en/apple.html
Under the heading: "How to build MacOS 7.5.5 from scratch !" it specifically says that:

"You can do a full installation "Universal System for any Macintosh", but you must exclude the system extension "A/ROSE" for use with some Mac emulators like "Basilisk II". If you forget, the emulator crashes. Remember that by keeping the shift key pressed at startup, all extensions are disabled so that "A/Rose" can be safely moved out of the extensions folder."

BTW I was running AmigaOS 3.1 at the time, not 3.9.  It may/may not matter.

If A/ROSE can be disabled by disabling extensions at startup then A/ROSE is not my problem since the ShapeShifter/Amiga still crashes. **I can't find A/ROSE in any of my installations.** I'll have another look, but again skipping extensions at boot hasn't helped.

 I had to do a Universal installation of MacOS 8.0 ( and then upgraded to 8.1) to boot into it.  When I installed MacOS 8.0 off the CD and did a universal installation I always ended up with A/Rose getting installed and having to be removed before I could boot.  The fact that you don't have A/Rose and you haven't removed it suggests that you might not  have a universal MacOS installation.  Or may be there are variations of MacOS 8.0 install CD's with variable compatibility under emulation.

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.
