bootloader 0 and 1

Hello has all here is I would like to know if bootloader_0 and bootloader_1 are identical

To sadden for my English j uses a translator

I have 2 bootloader because I am on ps3 nand

But during a dump I had errors thus I would like to know if it is normal to have 2 identical even md5

All the other file I have no problem it have was dump with jailcraib preloader but him not dump not bootloaders

thank you all
