That's not quite true -- they're upward compatible, but not downward (the 1542B supports scatter/gather I/O, the 1542A doesn't). As long as you just use the on-board BIOS the cards are interchangable, but if you plan to use an external driver (like for Unix or OS/2) be sure it supports the 1542A. ---- Larry Jones, SDRC, 2000 Eastman Dr., Milford, OH 45150-2789 513-576-2070 larry.jones@sdrc.com or ...uunet!sdrc!larry.jones We seem to be out of gun powder. -- Calvin
