06.027 How can I create bootable ProDOS diskettes?
Creating bootable ProDOS diskettes is more bother than creating bootable
DOS 3.3 diskettes because ProDOS does not have any way to duplicate itself from
memory-- i.e., it has no INIT command.
One way to make a new bootable ProDOS diskette is to first use Apple's
ProDOS FILER utility or a ProDOS version of Copy II+ to FORMAT a diskette for
ProDOS. This creates tracks filled with blank blocks so that the diskette can
be used to hold ProDOS files. It also writes boot startup code in Blocks 0 and
1 on Track 0.
ProDOS is in a file on a bootable ProDOS disk and so, usually, is the
ProDOS 'connection' to BASIC, named "BASIC.SYSTEM". To finish the job you copy
BASIC.SYSTEM and PRODOS from some bootable ProDOS disk to the new diskette.
Another way is to use Disk Muncher or some other whole-disk copier to copy
some bootable ProDOS diskette which includes BASIC.SYSTEM. You can delete any
files you don't want from the copy.
Things are a bit easier on a IIgs running GS System. In the Finder (the
usual GS main 'desktop'), you can insert a blank diskette and let Finder
"Initialize" it for ProDOS. Then you can mouse 'drag and drop' PRODOS and
BASIC.SYSTEM from a bootable ProDOS disk to your new disk. (Or, even easier, if
you have a 'stock' blank bootable ProDOS diskette the same size as your new
disk, you can just drag and drop the bootable disk onto your new disk.)
Note: If you want to copy the ProDOS used by GS/OS, copy the file P8 from the
SYSTEM/ folder and rename it to "PRODOS" on your diskette.
