[Coco] Dual boot OS-9 CF image

[Retro Canada]

i had to include sysgo because its a dual boot and the sysgo is not the same as level2 which is already on root dir. who calls it? i can change the default name and put it on root dir so it can coexists with level 2 sysgo.

is it krn? boot-ide? i need to find on source code
