I have System Picker and a 7.5 Network Access disk that I modified to fit a patched Apple HD SC Setup. The drive is formatted with Silverlining 5.4.2. How do I make another blessed System Folder on my HD so I can properly select that System Folder with System Picker and subsequently boot from 7.5?

FYI this is a PowerBook 160 with a non-Apple ROMed Quantum hard drive.
