Looking for code for Western Digital 33c93 SCSI chip

[Ronald G Minnich]

I have a card with a Western Digital 33c93 scsi controller chip.
I need to write a driver. First, however, i want to see if anyone
else has done so, and if they are willing to hand their code off to
me or point me at some piece of a publicly available system which 
has such a driver. I hate reinventing wheels.
Many thanks,
ron
