Hello,
I have a ucs c220 m4 on which I have done a firmware upgrade and the CIMC secure boot was enabled during the firmware upgrade.
now, I'm getting the signature violation message.
The server has no OS at all.
I want to install esxi, proxmox or any other OS's.
Is there a way to undo the CIMC secure boot?

Thanks for reading this topic
the solution is to downgrade the "bios" to a version that has the ability to disable secure boot.
2.0.6b - 2.0.9b

This worked, but only after downgrading bmc to the same fw set. The problem now is that CIMC is inaccessible because "This application requires adobe flash player" and that doesn't exist anymore!

You can use Flash Browser to access CIMC. It works perfectly. Find it here: https://flash.pm/browser/
