I made a flash drive into my "a:" drive. Compiled and everything worked like it used to as far as the lst files and hex files coming up in the drive. I tried to get the micro to load and run it and it just sat there. I can get the monitor program and stuff so it's communicating. It'll just repeat the name of the file I'm trying to load followed by a bunch of those little "A"s with the little dots over them. and then it just sits there. Thanks for any other idea of what I may can do.
