Documentation to enable secure launch

[arijit8972]

Hi,

Could you please provide a reference to how I can enable secure launch with Intel TXT and Ubuntu 22.04 (it's ok even if it is not OS specific) ? I was trying to follow the Quickstart guide to enable trenchboot but the instruction seems ambiguous to me on how to enable the Secure Launch grub menu entry. Is it manual ?

It would be very helpful if you could provide some details on this. Thanks in advance

Another follow up question on this. Does trenchboot support legacy bios or just UEFI ?

To get a Secure Launch to occur, the GRUB config needs the "slaunch" command set before the "linux" command. I suppose there are numerous ways you might go about updating your GRUB config for this. There is an example in the quick start guide. And yes, it supports booting a Secure Launch Linux kernel using either legacy BIOS or UEFI.
