Ah, DDO meants disk overlay? Didn't know that so wasn't sure what chuck meant, sorry. That does sound like a rather decent solution, in that case I could find any old low capacity IDE drive and just use that. That way I've got a decent amount of storage (300-500MB hopefully) and HDD sounds. How would I install such a tool though? I've currently got no way of getting files on and off of it (part of what I hoped a CF card solution would solve). I get that CF is possible, but I was thinking of something along the lines of a card you could buy (modern production) that will already have XTIDE BIOS loaded to it, like the 8 bit stuff that's out there for XT systems. Seems like a catch-22. Can't get a drive working without that software plugin, can't get the software plugin without a drive working. Unfortunately I don't own a bridge machine with both size floppy drives, and the Deskpro has 5.25" only.
