I noticed that the latest Adaptec Driver is dated 2004.  Obviously, there have been many updates in 3 years.  I specifically need:
1420sa: http://www.adaptec.com/en-US/downloads/ … AID+1420SA
and
2420sa: http://www.adaptec.com/en-US/downloads/ … AID+2420SA
drivers but there are many more, especially in SATA RAID, that, I'm sure, other people could use.
Thanks.
