The checksum won't match anyway because the goto at 0x00 is moved to just before the boot loader and in it's a goto to the boot loader is placed.
My checksum generation and checking skips the reset GOTO at 0. The difference between MPLAB and bootloader programming is two words at 0x100 (the start of the aivt which is a gap in the hex file) and a block after the last address (excepting the config words) in the hex file. These are FFs with MPLAB and 00s with the bootloader.
I have worked around the problem by filling in the gap with this
Code:
int hexpad[2] __attribute__ ((space(prog), address(0x100)));
