Dallase, could you upload that 570 rom please ?

Edit1:

You can easily fix checksum with ohgod..tool : https://mega.nz/#!zIwVXL4B!IUQOXRqWDw6L15rvN5gBgBN0hxc6ncQu5YcnG41m90g

Edit2:
I see now that 480 micron rom was uploaded & modified by me, but why do you want to open it in hawaiireader ? Cheesy

480 are polaris cards, not hawaii Cheesy

You mean PBE doesn't work?!

It does work, most 5xx bioses now contain 2 memory profiles, like elpida/micron 4xx.

There is a fork on github that already supports the 570/580 BIOS, I cannot recall which one offhand but it's one of the recently active forks...

unable to find it, can you help ?
