Use the command os9gen /d0 on a blank formatted floppy on drive 0, you will need to provide it list of all the files you want in you new os9boot file. You can get a list of the files in the current os9boot file by typing ident -s /d0/os9boot with a current boot floppy in drive 0. You can save out files from the current boot in memory using the save command. There are newer, fancier way to generate a os9boot, but I am giving an example using only the original commands so…

1) ident -s /d0/os9boot
This will give you a list of what is in your current boot.
2) Put a formatted floppy in drive 1 and run
chd /d1
Using the save command, save out each file from ram that you want in your new boot.
Example:
save krnp2
save ioman
Etc..
3) Type in the following:
load os9gen
load copy
load makdir
(Optional)
load dir
4) Put a blank formatted floppy in drive 0 and type:
os9gen /d0
Type in the name of each file you previously saved, then type a blank line.
5) Put your current system disk in drive 1 and type:
copy /d1/sysgo /d0/sysgo
makdir /d0/CMDS
copy /d1/cmds/shell /d0/cmds/shell
(Optional)
copy /d1/cmds/grfdrv /d0/cmds/grfdrv
Copy any additional commands, such as dir, etc.

I think that’s everything.
