asr and the modern era

[Jon Noack]

Hey all,
I have an Adaptec 2100s, a spare machine (i386), and no lif^H^H^H 
project at the moment.  It seems that the asr driver is rather unloved. 
  I would like to rectify that in my awkward, teenage boy 
coming-into-his-own way...

I'm not familiar with any of the code in question, so this will be a 
learning experience for me.  I hope it will be beneficial for me and 
others.  What I would greatly appreciate is any help/pointers to get me 
on my way.  My (admittedly uninformed) goal is to complete the steps 
outlined on the busdma page 
(http://www.freebsd.org/projects/busdma/index.html).  I contacted David 
O'Brien about any progress he's made but have not heard back from him (I 
assume not much has happened here).  I would especially appreciate 
comments from those who have performed these same steps for other 
drivers.  I hope to acquire an amd64 machine at some point to help test 
these changes.

Given my lack of experience, this is a bit overwhelming, but I plan to 
dive right in.  Direction to the deep end of the pool would be very 
helpful ;-).

Thanks,
Jon Noack
