After an evening of installing emx+gcc for OS/2 I have gotten a compiled binary to run on my machine. Its chugging away at 5100 keys/sec. If you want to try out my binaries, ftp over to: ftp.eskimo.com/~blane/brutessl/bruteos2.zip I have included the .exe, the .txt file and the .pf files for hals 2 challenges and the test.pf I think I have it compiled so that you don't need emx.dll on your system, but I can't test it(I have emx installed). Let me know of any problems. I tried the os/2 binaries from the ftp.brute... site, but they insisted on running the DOS command.com shell, and then dying with an error. Good luck!
