Hi
Just wanted to upgrade the CIMC firmware on a SNS-3594-K9 appliance, which is basicly a C220M4 UCS server. But the ISO image (from Cisco) for the firmware upgrade comes without the necessary signature for UEFI Secure Boot. Unfortunately the SNS-3595-K9 firmware does not allow me to deactivate the Secure Boot option for upgrading the firmware. :-)
Does anybody have an idea how to break out of this dead lock?
Regards
Roberto
