Secure Boot and Intel 630 Integrated Graphics

[wesstrueb]

The other day I asked a compatibility question (any NVIDIA cards compatible with Odense2-K mobo...) Some related questions/answers indicated that I *might* get my older NVIDIA card to work if I disabled the secure boot. Now, I know that if one installs a video card, the Intel Integrated graphics 630 will automatically disable itself to use the card, but I have also heard in some circles that disabling secure boot will disable the integrated graphics, too - which obviously would cause problems if the video card doesn't work, because how, then do you see the UEFI BIOS screens to reENable secure boot? I'd much rather find a compatible card, but are the fears that disabling secure boot could put one in a situation that one can't recover from even accurate?

Does my query even make sense?

Thanks in advance!

Hi wesstrueb

Please check out this MS Technet article on Secure Boot.

I disable this all the time when replacing graphics cards.

All factory installed devices as well as custom add in devices will function when Secure Boot is disabled.

Many UEFI systems allow creating custom keys based on new components connected to the motherboard. This gives you the extra boot time security which Secure boot offers.

This means if you create a custom key set after adding a discrete graphics card the PC will not post if you remove the discrete graphics card.  This can be fixed by disabling Secure boot before going back to the integrated factory graphics.

After doing this you can recreate original Secure Boot profile to enable all factory installed components.

Thanks,Gzwacz;

I will check out that article, but short answer, if I uderstand you correctly, is that disabling secure boot will NOT disable onboard (factory-installed) components like integrated graphics, especially if the attempt to install a graphics card fails.

THAT is a good-to-know piece of information, and a load off my worried mind.

Hi wesstrueb

You are correct.

Disabling Secure Boot has no effect on using factory installed components.
