DZ77GA-70K - secondary SATA port problem with secure boot - Question

Good morning, everyone.

 

For a long time I solve a problem with an external SATA port on the Armed UEFI secure boot. Secondary Discs are visible only in legacy mode, or when turned off UEFI. I tried the instructions in various discussions downgrade and upgrade the bios, but always with the same result. Should not somebody please advice or a solution to what to do with this horror can be done?

 

Thank you very much for your response.

SiggiTron,

You seem to be saying that you are upset because external devices are not supported for UEFI secure boot. I believe that this is intentional. The concept of secure boot is that the BIOS is certifying to the O/S that a chain of trust exists for all devices. I do not believe that it can make this claim with an external device in the picture; it could be replaced at any time by anybody. You will need to choose whether you want an encapsulated secure system or an open insecure system.

Just my opinion...

Hello Scott, thank you for your response. Problem solved downgrade from

BIOS rev. 66 to 64. I use linux system with LVM array disks and there

are already correctly seen as UEFI Secure mod.

Have a nice day

Siggi
