Identifying an unknown bootloader

-

hi,

i've got couple of pro mini's bootloader.

i tried identify bootloader reading flash to
my harddisk , search resulting file strings.
but found nothing appropiate.

is there other way identify bootloader?

thank in advance help!

best regards,
mcc

you can try comparing upload various bootloaders in arduino distribution might not 1 of them.  it should 1 of these:

pro mini:
328p 16 mhz: hardware/arduino/avr/bootloaders/atmega/atmegaboot_168_atmega328.hex
328p 8 mhz: hardware/arduino/avr/bootloaders/atmega/atmegaboot_168_atmega328_pro_8mhz.hex
168 16 mhz: hardware/arduino/avr/bootloaders/atmega/atmegaboot_168_diecimila.hex
168 8 mhz: hardware/arduino/avr/bootloaders/atmega/atmegaboot_168_pro_8mhz.hex

mini:
hardware/arduino/avr/bootloaders/optiboot/optiboot_atmega328-mini.hex
hardware/arduino/avr/bootloaders/atmega/atmegaboot_168_ng.hex

you burn fresh bootloader know have.
