How to prepare dual boot system?

[JRL]

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.

Have the FWB Harddisk Toolkit software (HDT). I managed to use it to set up a PB 180 with several partitions on the internal harddisk drive. Each partition (=volume) may contain one blessed system folder. Use HDT to configure which volume shall be the standard boot volume for a given SCSI ID (which is stored in the PRAM as a boot volume). You may force the Mac to boot into any bootable partition at early startup by use of a key combo (it is like cmd-opt-shift in combination with the partition number). To get the details read the manual, please). The version of HDT I used was 2.0.1.

FWB Inc. seems not to exist any more, sadly. Is there any supply of the most recent HDT version available ? The version number stalled arround 5, I think.

My HD Toolkit is the Personal Edition version, which took out some features, so I may just use Silverlining in this case.

BTW, I was talking about using System Picker, which involves two or more System Folders in one partition. I wanted to do this so I could just simply use System Picker to change the boot System Folder via software control.

System Picker only does the job of blessing one chosen System Folder at a time. You may have several System Folders on one volume, but only one blessed at a time. So System Picker works fine, as long as you know into which System Folder to boot next time, each. A multi partition HDT formatted disk would allow to choose at boot time, though.

OS 9 comes with a Startvolume control panel that allows to choose from multiple System Folders on one volume. This might work with earlier versions of Mac OS, as well.

So how do you get the 7.5 System Folder on the drive? You can't just copy it, right?

System Picker should work fine with Silverlining. If I recall it came with Silverlining on the LaCie version of Silverlining (along with DiskDup+ and TimeDrive), which shows promise in terms of compatibility. I don't think I've ever used it on that drive...a nice 160MB unit that I got for my seventh birthday...

(insert loud "NERD!" insult here...what seven year old asks for an external hard drive anyways?)

Just to make sure, just copying the System Folder from the Network Access disk will not work, right?

I am not sure if I understood what the problem is. Usually you can just copy the System Folder to any other volume the computer can mount at boot time and it works fine. Paths from aliases might get messed up, but can be fixed manually (for example aliases of application programmes you put in the Apple Menu).

Cloning of any pre-X-toric Mac OS is easily done by copying, except some varieties that want to work from a CD, only.
