I just bought a 3167 Weitek math co-processor for my '386 clone. I stuck the thing on the board, but it doesn't seem to be doing anything (the board cmos setup can't find it). No jumpers are listed for it on the board (just a '387 enable, which works fine with the '387 that was replaced, but locks up the machine with the 3167). Is there something I should be doing to activate it? Right now, it seems to be just along for the ride. Has anyone else had trouble getting it to work? - b2wild -

Software that requires a '387 will not use the Weitek 3167 instead, and your system will not recognize it as a '387. It is for this reason that many (most?) 3167's are shipped on a daughter- board that also permits simultaneous installation of a '387 chip. In order to get any use of the 3167, you must run software specifically written to address it. At least, this is what I recall from my research on the subject. ---------------------------------------------------------------------------- Mark Medici/SysProg3 * Rutgers University/CCIS * medici@elbereth.rutgers.edu ----------------------------------------------------------------------------
