Hi.  I'm trying to do I/O to my harddisk device, "overdrive.device".
What steps do I have to take to access a presumably previously
open device?  Is there a pre-existing req struct and/or port
I should be using?  I've been following the example code in
RKM for the "trackdisk.device", replacing every "ext" thing
with its "std" equivalent.  OpenDevice returns -1.  I can
open the printer and gameport however.  I'm using Manx 3.6a.
What do programs like "diskx" do?
Also, where can I find the ".h" files that describe FFS structures.
Documentation too..., the LATEST RKM's (mine are the first rev.)?
HELP HELP HELP, THANKS THANKS THANKS!!!
