A recent posting on comp.sys.mac by Rob Jellinghaus (under the subject
"Re: Keeper II") suggested that you can keep a disk the System Disk by
renaming its Finder to something other than "Finder". I haven't tried
this, but I assume that it would work. However, I don't understand
WHY this would work.
Back in MFS days, I understood the rules for switch-launching: if
there's a System and Finder on the disk with an application, that disk
becomes the System Disk when you launch the application. But ever
since the advent of HFS and hard disks, the rules have changed. For
example, I believe that launching an application from a floppy with a
System and Finder does NOT switch-launch if the current System Disk is
an HFS disk larger than 800K. There is also a "switch-launch" bit in
the file header, but I don't know how it works.
Could someone with access to recent versions of Inside Mac and the
Tech Notes (I have only IM volumes I-III) please mail or post a
summary of the current rules for switch-launching? I'd appreciate it.
I need this information because it's vitally important to have the
correct System be active when printing to a Linotronic from
ReadySetGo. But that's another story...
