Legacy support missing

[dotzball]

Dear Support Team,
I am looking for the function "secure boot configuration" in the BIOS to set "Legacy Support Enable and Secure Boot Disable".

Background: I am using HP Z2 G5 Workstation (BIOS version 01.01.08). I need the legacy support because I want to use a sapphire graphics card (GPro 6200) in my workstation. In the past this was no problem with my Z2 G4 workstation (Bios version 01.00.05). As soon as "legacy support" was activated, the computer booted and the graphics card was recognized. However, with the new Z2 G5 workstation, I found that the BIOS has changed dramatically and this feature seems to have disappeared.

what can I do?

Thank you

Bob

your video card is a UEFI class 2 card, meaning it supports both UEFI and Legacy Bios extensions as such the card will provide a display output no matter what bios mode is selected (UEFI or Legacy)

Dear DGroves,

Thank you for your feedback. That's good to know that the card supports both. Unfortunately, the problem remains that the HP workstation prevents the boot process. With my old workstation (Z2 G4) I was able to solve the problem by selecting the option "Legacy Support Enable and Secure Boot Disable". Since you report that Legacy doesn't seem to be essential, the problem is probably with Secure Boot. As soon as I installed the graphics card, the computer stopped booting and gave me an error message: three long beeps followed by 3 short beeps. Unfortunately, it doesn't matter if I checked "Secure Boot" in the BIOS or not (BIOS -> Security -> Secure Boot Configuration -> Secure Boot).

I am at a loss and would appreciate any help.

Addition:
Here is the answer from Sapphire Support: The card requires a motherboard with PCIe 2.0 and a legacy environment. If you are using a motherboard with a UEFI requirement, then UEFI would need to be disabled if the motherboard offers this option.
