So, ich hab das Problem nun gemeistert und eine GS/OS Bootdisk (via PC und "klassischem Mac" erstellt. Die Vorgangsweise:
- Look for 800 KB disk images, usually with file format = "Unadorned raw data", physical format = "sectors", file size = 819.200 Bytes
- Use CiderPress on the PC to convert images into file format = "DiskCopy 4.2", file size = 838.484 Bytes
- Use "Basilik II" (MacIntosh emulator) on the PC to copy the converted image file to an 1.4 MB disc in Apple MacIntosh HFS format (use of USB FDD is possible)
- Copy the disk image to the hard disk of an old MacIntosh (e.g. a MacClassic running System 6.x)
- Use Norton Utilities / Disk Editor to set correct file type for DiskCopy (Type = dImg, Creator = dCpy), otherwise DiskCopy will ignore the disk image
- Use DiskCopy 4.2 to write the disk image to an 800 KB DD/GCR disk
- Open the 800 KB DD/GCR disk on the Apple 2gs
