[Coco] Glenside IDE Controller Question...

After swapping out a few drives and changing my controller to a FD-501, the
thing came to life.  While the IDE card was plugged in and power on, I changed
the jumper to 70 from 50 and then the thing starting working.  I am a 
bit puzzled
as I thought the floppy was at 70 and per the Glenside doc, the 
jumper should be
in the 50 setting with a multipak controller.  Oh well.  At least I 
know the card is
reporting a real life hard drive on the end of it.  I also used an 80 
pin cable.  Don't
know if it helped, but...

OK.  My OS9 knowledge is pretty limited.  I am very good with 
operating systems (DOS
level commands, etc), but when it comes to configuring boot diskettes 
and setting
up descriptors, that is alien talk to me at the moment.

Is there a step-by-step procedure I can find somewhere to get a boot 
diskette set-up where
I can lformat the drive?

Also, I see the update files for the IDE controller, but what is the 
process to get them copied
to 5.25" floppy diskettes?  Are CoCo diskettes in the same format as 
DOS and I just need
a DOS machine with a 5.25" drive to copy the files over?
