One of the courses at the Microchip MASTERS seminar specifically addressed the issue of bootloaders in the PIC18 series. It skimmed the class notes and they were reasonably detailed. The PowerPoint slides, etc. were on the CD-ROM given to attendees. I do not know if the CD-ROM is freely available -- you may want to contact your Microchip rep and inquire whether he can get you one. -- ______________________________________ Andrew E.
