[Coco] Swapping hard drives with SuperIDE

[Diego Barizo]

My original plan was to use 2 had drives (actually CF cards), 1 for 
HDB-DOS, the other for NitrOS-9, and swap them as needed.
Today I was going trough the steps to setup a floppy-less NitrOS-9 
installation, and some issues came to my mind.
In order to boot from the CF, I will need a HDB-DOS partition of at 
least 1 disk size, to contain the actual boot disk. This partition will 
reside after the NOS-9 one, and HDB-DOS will use an offset to avoid 
writing over the NOS-9 partition.
But that means that I can not just swap that CF card for another one 
with a different configuration, since the HDB-DOS partitions will start 
in different positions... Right?
I guess that the right thing would be to use one of the flash banks in 
the SuperIDE for each CF card?
Is there any other way to have a floppy-less system, besides a custom 
NitrOS-9 ROM?
