My PC cannot operate in Secure Boot without its Bios running in EUFI mode.
I know that AMD produced a UEFI BIOS upgrade for this card - Radeon R7 200
I am trying to get an PCIe SSD drive to run on a ASUS Sabertooth 990fx R2.0 mother board.
It will only run if the BIOS is in EUFI mode which is not possible with the standard GPU bios.
Try contacting the card maker (asus, xfx) ?
Thanks for the reply's.
Still haven't any success.
I tried the ASUS and Sapphire websites, but no help.
I have seen an article from AMD that they produced a BIOS fix for this problem.
Well the R7 2?? series is a while back.
You could try email support https://www.amd.com/en/support/contact-email-form
They will probably need the exact make/model of card, especially if it is a HD7???/R7 2?? version.
