The bt driver has always supported the BT958, even before it existed. :-) The bt driver supports *every* BusLogic SCSI controller, with the same interface, except the new FlashPoint controllers. Consult http://www.buslogic.com/ if you need help telling the difference... There have been a whole ton of posts on this, already (especially in the last couple months on current-users and/or port-i386@NetBSD.org -- you might want to see if it's in the archives over there). The Adaptec is a more modern design with lower command overhead. On very fast drives, on a very fast system, it has the potential to be faster. On my system (cheap drives, 486), I doubt I'd know the difference (I use the BusLogic BT747 EISA controller). The BusLogic is an excellent quality controller, but the technology in the BT742-based designs (which includes the BT958) is older than the Adaptec 2xxx controllers, being more like the Adaptec 174x. ----------------------------------------------------------------------------- Michael L.
