Craig: Thanks for your reply. I realize that the NEWDX program is intended to provide DPMI compatibility, but AutoDesk is intending to standardize on it "sometime soon" (according to developer support). I only tried it because of my other problem. What I really want to do is write and run C programs in real mode. This requires loading AutoCAD, xloading pwedge.exp, rloading my program and running it. I have yet to find a combination of memory manager (or lack thereof), DOS version, Phar Lap extender version and AutoCAD configuration that will allow me to do this. The closest I have been able to achieve is with the Phar Lap extender v2.2d, plus either no memory manager or QEMM386. In this configuration I can get up to the point of loading my program, but when I run it, it either hangs or reboots(!) the machine. Any other combination just causes things to fall apart earlier. (My program, by the way, runs quite happily on other machines, so it's not that) The only reason I mention the upgraded Phar Lap extender is because it gives me the "Abnormal program termination: Illegal instruction" message before I even get to AutoCAD's main menu. I suspect that both problems have a common cause. The 2.6 extender loads its code into extended memory unlike 2.2d, thus requiring switching between real and protected mode. Pwedge functions in the same way. As for talking to my dealer, unfortunately, I AM my dealer. The CPU and FPU check out OK according to diagnostics. I'm stumped. Gary
