UCS Diagnostic ISO

[injector22]

I'm trying to test the RAM in one of our blades using the Diag ISO

https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/sw/ucs_diagnostics/b_UCS_Blade_Server_Diagnostics_User_Guide-2-0/b_UCS_Blade_Server_Diagnostics_User_Guide-2-0_chapter_01.html

But the blade is not seeing the ISO as a valid boot option when I mount it via the KVM. The boot policy allows CD booting and I can even mount a Server 2016 ISO and that is detected fine.

Anyone know if there is something special required to boot off the diag ISO?

Figured it out, Blade has to boot in legacy mode.
