Hi all,

I bought a RX570 to upgrade my girlfriend old computer (a Intel DP55WB motherboard with a very good CPU, and a old crappy video card).
The RX570 doesn't boot on her computer, but works fine on mine (MSI X370 Gaming with Ryzen 2400g). So I heavily suspect her motherboard is not compatible with some newer UEFI/Legacy vga cards.

As for others, I'd like to edit my bios but it looks quite tricky to do, and I don't want to brick the card. Here is the RX570 vbios I exported with GPU-Z.
Can you mod it to remove the hybrid UEFI/Legacy bios in order to boot on that old mobo ?

Thanks a lot !!!

This motherboard dont even worked with some gpus (for example r7 260 amd) back then. It need bios update but i cant find in intel site they removed it.

Yep, there is no firmware on intel's website, but there is no new firmware since several years (5 years or more maybe...). I have the latest one. I also tried to play with the legacy/uefi boot option, but it seems not related, since the BIOS stops at POST (don't remember the error code, but was related to disk or memory initialisation, nothing plausible, since the video card works well on other computers).
One day I will try that method for disabling UEFI from the bios image, if nobody do it for me...

After some background reading I took the plunge and edited the BIOS for a cheap MSI rx470 mining card I picked up to upgrade an old HP Pavilion HPE.

I was feeling pretty worried about bricking the card (I don't have a background in programming/hexadecimal) but it totally worked! Thanks @drbob !!
