Hello, once I tried to get the compressed version of the ramdrive going I started to get some odd errors. After lots of dprintf statement found the problem. Device drivers /BFS do not work exactly as the docs I could find say they do! I would like to leave notes to help future developers, where would be best? Presently I found http://www.haiku-os.org/documents/dev/driver_development_presentation_waltercon_2006 http://www.haiku-os.org/documents/dev/device_driver_basics Would either be the right place to post such a note, or do you suggest else-where?
