Possible leads most likely require further analysis of the installer script and perhaps manual copying/creation of the expected volume scheme to create a bootable system I believe this is because the installer can't write a boot partition at all, preventing any progress in booting at all SheepShaver segfaults during the happy Mac before any Copland-related code loads (looks like it doesn't even load boot resources) The installer script can be modified in Resourcerer to bypass the checks for a compatible Macintosh and partition scheme Possible leads include further analysis of nkld and ModernOSLoader or modifications to SheepShaver itself so that it more accurately emulates a 6100, 7100, or 8100 device-tree, allowing Copland to find the "GDevice" without modifications And that's about all I've figured out so far.
Segmentation fault, crashing the emulator With some NOPs in the nkld code (use Resourcerer), this error can be bypassed, and the boot process proceeds as follows: This resource draws the boot screen and finds devices and volumes, and eventually shows the "Failed to find main GDevice" error The codes in the boot resources #1-3 run first, and call the nkld resource ("NuKernel loader" perhaps?) The initial boot code is inside the System suitcase on the 7.5 volume ("scarecrow volume") They expect a NuBus based Power Mac, SheepShaver emulates a PCI one I've made the following discoveries, resulting in somewhat more progress: Custom Drive Setup bundled with it can't initialize SheepShaver's weird "big floppy disk" drives Can't be installed in SheepShaver because it needs a weird partition scheme Boot messages and eventual error are the same, but the graphics are more polished
Installable in SheepShaver by manually following the install instructions that come with the software I've tested 3 builds, to different results:
It would be really awesome to get this working on a modern machine since Power Macs aren't super easy to come by anymore. I thought I would quickly summarize my efforts/progress and see if anybody wants to help out. Hey all! As far as I know, nobody has really put much effort into installing any Copland builds in an emulator.
