NCR/Symbios may not be (have been?) perfect, but, performance is pretty good across the product line, and, at least the programming information was widely available, and, you could also buy driver-compatible controllers from multiple vendors, including inexpensive no-frills like the ASUS I own, to fancier, more heavily marketed Diamond controllers. With the acquisition of Symbios, is there *any* open chipset family available in multiple controller incarnations from different vendors? Does Qlogic sell its chips on the open market- and, if so, is anybody buying (what are the other sources?)? -- Hugh LaMaster, M/S 233-21, ASCII Email: hlamaster@mail.arc.nasa.gov NASA Ames Research Center Or: lamaster@george.arc.nasa.gov Moffett Field, CA 94035-1000 No Junkmail: USC 18 section 2701 Phone: 650/604-1056 Disclaimer: Unofficial, personal *opinion*.
