Copland

Copland has beaten me so far.

Copland D7E1

Haven't tested it yet.

Copland D9 "Tools Edition"

On the Power Macintosh 7100/66, at least, the CD isn't bootable. My System 7.5 CD isn't bootable either. So, I perform a somewhat modified setup procedure.

1. Boot from the Mac OS 8.1 Disk Tools floppy (System Software 8.1DT3)
2. Create the two HFS partitions with Drive Setup Lite
3. Insert the Copland D9 CD
4. Install System 7.5 to the first partition using the Copland CD's copy
5. Create the No Copland Mount file on the first partition
6. Proceed as normal from there

When I boot into Copland, I get a "Failed to find main GDevice." error that I can't get past.

Copland D11E4
