Bootloader firmware for x51 and at91xxx microcontrollers, can be easy targetted to other microcontrollers. Supports encryption (RC4 algorithm) of ROM-file. ROM files uploading with X-modem protocol (firmware uploading program for PC is in archive too). Can be used for updating ROM in any microcontroller-based device connected to serial port (via USB-adapter). Uploading can be automatically started if connected computer continuously transmits magic sequence in serial port during device power-on.
