- Hey all,
-
- I wrote a program called 'BootSel' and am looking for ways to
- expand it. BootSel replaces the PRODOS file on a disk. When the disk
- is booted, it looks at the apple/command key and uses that to determine
- whether to load GSOS or ProDOS/8 into memory. It then loads the
- appropriate file and executes it. What I would like to do is to make
- it so it can either boot ProDOS/8 normally, or tell ProDOS/8 to run a
- specific SYS file when it starts rather than just running the first
- .SYSTEM file it finds. Note that when BootSel runs, ProDOS/8 isn't in
- memory yet, so I can't just load another SYS file and run it; I have to
- somehow modify the ProDOS/8 startup code to run whichever SYS file I'm
- looking at.
-
- Thanks,
- - john
