User`s guide

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.

028- How do I make a ProDOS disk that will boot and start
a BASIC program?
If you want ProDOS to boot and start a BASIC program, then both PRODOS and
BASIC.SYSTEM must be present. (BASIC.SYSTEM should be the first .SYSTEM file on
the diskette.) The "hello" program on a ProDOS diskette is named "STARTUP". This
is the program which will be run upon booting the diskette. (If there is no
"STARTUP" program, you will end up at the usual BASIC prompt after booting.)
A simple STARTUP program you can type in and save to your new ProDOS
diskette is ...
10 TEXT: HOME
20 PRINT CHR$(4)"CAT"
30 END
After typing in the program, just enter SAVE STARTUP. Next time you boot
the diskette, the above program will run and the diskette's CATALOG will be
displayed.
A good ready-made STARTUP program and program selector for launching ProDOS
8 programs on a IIgs is available as speedgs.shk. The file unShrinks to the
Startup program and a Readme directions file. To get speedgs.shk from the net,
see Csa21MAIN4: Get It- Links to popular software packages.

029- What is the maximum size of a ProDOS volume?
When a diskette is formatted for ProDOS it is given a name by the user. A
ProDOS diskette is also called a "volume". A ProDOS hard disk will, usually, be
partitioned into two or more named volumes. The maximum size of a ProDOS volume
is 32767.5 kilobytes (65535 blocks).
