This was originally ported to BSDI by Andy Rutter <andy@acronym.co.uk>. At the end of the day, this code has very little in common with Andy's version, or the Specialix SYSV version. Essentially it has been gradually and almost completely rewritten, with LOTS of advice and inspiration from Bruce Evans. There are a couple of missing bits still, but they are minor. The user-mode "sicontrol" program is in sad shape and will come in soon. Transparent printing died a timely death.. Maybe later.. Jeremy Rolls @ Specialix (Development directory) has confirmed this is OK to distribute, and Andy personally sent me his version that I started from. Although this driver stood up to a nasty stress-test in this form, I am not confident that there are no nasty bugs lurking. People are welcome to try it, but dont go out and buy one just yet.. :-) And *DONT* use it on a mission-critical machine... This is ALPHA QUALITY!
