While we wait for software updates, some of us, perhaps many of us wish to run S6.0.x some of the time and S7.0 at other times. In the past, Blesser (1.1) was the method of choice for running multiple systems from the same boot disk, or Apple's "startup disk" in the control panel when the systems were located on separate hard disks. With S7.0 old methods don't seem to work. Blesser can't see S7.0's system file to bless it so that doesn't work anymore. I am running hard partitions under SilverLining (5.27) and "Startup Disk" doesn't work. I don't know if startup disk works with SL partitions or if its the particular combination of software versions that is causing it to fail Right now I have S6.0.7 on one partition and S7.0 on the other. In order to get one or the other system to boot I either: (1) alter the name of the partition so that the desired partition is alphabetically first, or (2.) Use SilverLining's DA to set the partition containing the undesired system so that it won't mount at boot time. Neither of these methods is very elegant. Is there a better way? (related aside: What became of the command-option-double-click method of switch launching?)

When I used the pre-released sys7.0b4, I found that the Blesser will recognize the file with signature of "ZSYS". The new system(7.0b4) has signature of "zsys", so if you want to do it, at your own risk, you could make some modification. I don't have releases S7.0 yet, has any one mixed the S7.0 and S6.0.x successfully? My hard disk's volume information was changed after I installed pre-released S7.0b4, I am really afraid of this happens again when I install the released S7.0 Xinjun txhou@king.mcs.drexel.edu

hello, i have both system 6.0.7 and system 7.0 on one partition and i use the "System Switcher 1.1" to switch between these two. i got this via ftp. everything seems to work fine, although somebody told that the System Switcher would not work with System 7.0. regards joerg --------------------------------+------------------------------------- Joerg Wedeck | E-Mail: wedeck@peanuts.informatik\ Universitaet Tuebingen | .uni-tuebingen.de Lehrstuhl fuer Techn.

I'm not sure if my method is the most elegant, but it does seem to work just fine. When you want to boot the other system, just take the Finder of the system you are currently running, and put it in a different folder so that it is separate from the System file. (I just keep a folder in the System Folder for this purpose. I call the folder 'New Finder' in the 7.0 System Folder, and I call it 'Old Finder' in the 6.0.X folder.) After you do this, the icon for the current System Folder will revert to a generic folder icon. You now should have no bootable systems on the drive. Then, take the Finder of the system that you want to switch to, and put it back in its appropriate System Folder with its System File. You will note as you do this that the icon denoting the "real" System Folder will move to the folder of the system that you wish to switch to. Then reboot. Voila, you are now running the other system. Note, however, that you will probably still have to rebuild the desktop file when you switch if you have done a lot of adding and deleting files, but that is true no matter how you switch systems. Also note that it DOES MATTER in what order you do the above operation. You need to disable the current system BEFORE you re-enable the other system. This will allow the current system to properly decide which System Folder is the one that it should boot. One caveat on this method: I have not tried it on a disk with multiple partitions, but it ought to work the same way.

I use Silverlining which supports hard partitions. I have a partition which is my boot volume for 6.0.5 and another partition which is my boot volume for system 7. All my applications and data files are on additional partitions. The boot volumes contain ONLY the files needed to successfully boot and configure the appropriate system. Switching systems takes a little time but no effort. I use the DA provided with silverlining to set the "mount at boot time" flag for the boot volume I want, and turn off the same flag for the boot volume I'm switching from. Then I restart from the special menu and go get another cup of coffee. Works for me.... peter c -- (O)(O)(O)(O)(O)(O)(O)(O)(O) (O)(O)(O)(O)(O)(O)(O)(O)(O) (O) !the doctor is out!

Then you will get only one desktop rebuild the first time that System 7 sees a partition. Thereafter, since they use the same database files, you don't get the desktop rebuild every time you switch as others have been seeing without Desktop Manager. At least this is what I have seen so far. I have not have more than one Desktop rebuild per partition even though I've switched many times. ------------------------------------------------------------------------- J. D.

I have two 105 meg HDs (one Conner, on Quantum Pro), both formatter with OnTrack System's Disk Manager Mac software (v2.25). I cannot boot from different partitions on the same drive--I tried setting things up this way, but it appears that (1) only the root partition for the drive is around at boot time and (2) it is only late in the boot process that the other partitions get mounted. As such, no dice for me this way. However, keep 7.0 on the internal and 6.0.5 on the external and swapping back and forth with SwitchBoot (INIT) works great. Configuration: Mac SE/30, 8 meg, 2 x 105MB HD, System 7.0, System 6.0.5, etc.... -- | Paul E.
