Hi, Asa last resort, I'm going to try to find a DOS program to program my warp board. I have a DOS program that programs my 80C196 board, so there shouldn't be any problems there. How do you run MPLab under DOS? I tried all the executables in the download, but none of them brought up what I was expecting. Typing in "MPLAB" at the DOS prompt brought up the windows version, not the DOS version. But the download asks you if you want to install the DOS version as well, which I said "YES" to. Hmmm.... Is there another DOS-based program that will work with the PICstart? Thanks to all the people who have helped me so far, I really appreciate it. Ben Hitchcock
