[Coco] [coco] creating boot disks

[George Ramsower]

I tried that. IT WORKS! The bootfile does not have to be the first thing on 
the disk.
What I did was create the CMDS directory with the required SHELL and GRFDRV 
in it. Then created the boot and it works.
 Now I'm having problems mentioned in my previous post with the different 
boot.
 Oh, HECK!

 While waiting for a reply on the BLOB problem, I'm going to create a new 
disk with the bootfile in the cmds directory. That should be cool looking.

 I'll let you know.
