but I need to do my own ISP loader.
Flash Magic is good enough for development, but it is not for production. It allow a lot of problems with production workers. They don't think Flash Magic is easy and as I said, I need something more.
FlashMagic can be configured to run automatically (one keystrole does it all) - tried it once and forggot how. Post "how to make FlashMagic run automatically" in the FlashMagic forum at www.esacademy.com.
You Do know that for the first ISP no 'funny signal levels' are required?
