Wrongo Chuck. Install puts about 20 bytes of code in the boot sectors and about
1000 bytes of whatever is lying around in memory PLUS the required 12 bytes of
info dealing with 1. This IS a DOS disk 2. A checksum 3. Where the root node
is on the disk. Interestingly enough this seems to be the function of the
boot code as well, except it returns a pointer to the RootNode memory structure
which is not the same as the disk's rootnode :). It also doesn't call anything
except FindResident (OpenLibrary doesn't work at this point in the bootstrap)
and then returns to whomever called it. ie the boot code DOES NOT call the dog.

If Motorola had wanted us to use BPTR's they'd have built in shifts on A regs
