Hi,
  I've just uploaded the first release of my quick-n-dirty PIC18F252/452
bootloader to the "Electronics" page on my website. I'd appreciate it if a
few people could have a play with it, benchtest it, hammer it, and generally
try and find any little bugs I may have missed.
  Basically, it's a PIC18F-series bootloader that uses the USART to transfer
data between the chip and the PC. Load the file into the uploader, hold the
PIC in reset, hit the "Upload" button on the uploader and put the chip into
Run mode.
  It doesn't upload the configuration data to the chip - I did this because
if the cfgword got mangled (i.e. bad data transfer, chip loses power during
flash operation, etc), the PIC may become unbootable. Needless to say, I
don't enjoy desoldering pins to reprogram PICs on boards that were never
intended to support ICSP...
