RX580 won't show BIOS when disabling CSM

[sirtoti]

Hi,

I tried contacting Asus, but they told me the original vBios was "intern/insider's information" so they wouldn't disclose it (isn't it funny?).
Well, I got a third party (the distributor) to take action, as it's quite certain they won't speak with a uninterested clerk (i had to suffer for more than 4 weeks of mailing, and doing things such as disconecting everything but proccessor, RAM, and GPU).
The card is still in warranty, but I'm just annoyed of their continous curve balls ("I've never seen that", "Please make a video", or "Are you sure you have the card properly plugged" are some of the -as we say here- "seabream's conversation" (nonsense talk).

I attached the last ROM I tried out, unsuccessfully.

I must admit I didn't try my luck with the GOPupd because of the warranty. Maybe that would have solved it, but...

He needs your original BIOS, one that definitely works on your card so he can add the UEFI content manually (the GOP file)

Those Bios all work, the ones which subsystem ID was teh same as mine. I got "wattman" messages when the asus software gputweak was installed, but my main problem was that I receive no output in the monitor until the windows login screen, so I don't receive video signal while in Bios or POST. The performance was allright with the two Bios listed in for my card.
These are the Bios eidairaman1 kindly found for my card in the repository

I don't have the original Bios right now. I'm trying to get Asus to provide one to the distributor.
