This 152x series of boards use the 62x0 and 63x0 series of chips. The aic driver is know to be flakey on many of these boards doing many common things. Someone needs to find the time to fix this driver. I have the programming info and a couple of cards, but my personal life makes it impossible for me to do any work on them at the moment. I will keep your message in mind when I do try to start on it and use a tape drive in testing. : Is this Adaptec 1520B supported by FreeBSD or do I have a fault with : the controller? I replaced the 1520B with a 1542 controller and all : is working fine. while there is a small chance that the controller is bad, it is much more likely that you've run into limitaitons in our driver. The 1542 is a ROCK SOLID card that will give you YEARS of happy and faithful service. Warner
