bootloader for atmega8 (smd version)

hello , i would like to flush a bootloader on a custom board that has the atmega8A-AU chip (smd version) and i want to use the internal oscillator now may question is which is the best bootloader to use (i know that most of the bootloaders are compiled from a 16mhz clock but i can recompile it if needed ) and what fuses should i set for the atmega to uses the internal oscillator

any suggestion its appreciated
