"org 0x4100" means 0x4100 _words_ from 0x0000.
(Unless you have a PIC18XXXX chip)
However HEX file addressing is in bytes.
So address 8200 is correct.
4200 must be wrong anyway. (You wanted to write 4100, didn't you?)
Don't worry about 16 bit words in HEX file.
Programmer uses the lower 8 bit only when writing EEPROM.
