I have a 286 with 2.5meg and I run the protected mode versions of the compiler and such. After I re-installed BC++ I couldn't get tkinst to run. It kept failing with "A20 already enabled" messages. After thinking about it I remembered that I had HIGH=DOS (or is it DOS=HIGH) in my config.sys. I took that out, rebooted, and the installation ran fine. I also installed td286 at the same time and it installed fine. I put the HIGH=DOS back in and things are back to normal. The result? tkinst (and maybe td286ins) don't work with HIGH=DOS but td286, bcx, tlinkx, etc. work just fine with HIGH=DOS. bruce -- Bruce O'Neel oneel@heasfs.gsfc.nasa.gov NASA/GSFC/STX/Code 664
