[REQUEST] IBM System x3400 M3 7379 & AES-NI

Hi people,

I have the same problem. My server is System x3400 M3 7379 with one Xeon E5606 processor. This processor support AES-NI.
I updated uEFI firmware but again the same problem occurs. In uEFI settings there is no option for AES-NI Enable/Disable.

Firmware Type Version String Release Date
IMM YUOOH5A-1.55 01/15/2018
UEFI Y4E160A-1.15 07/31/2013
DSA DSYT92O-4.01 02/01/2012

On IBM site it says it supports AES-NI: https://lenovopress.com/tips0808

@DeathBringer: What is above .fv file and how to put it in bios?
