Just an update, I read somewhere that i flash it without the ROM file, and i reflashed my card again without it. Now, I don't get the option for the BIOS of the card when the server boots.
But what I did, i connected all the hard drives via the new card and the Intel extender, and my unRAID VM read all the drives as they were before, even the assignment to the slots are correct.
Before i put my server into production, i want to be sure that it's ok and nothing is wrong.
Update
I brought the array up, and all was ok, and i tested spin up and down, and it worked. anything else i should test?
