[REQUEST] IBM System x3400 M3 7379 & AES-NI
#1
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

@AdamBearWA: Did you solve this problem?
@DeathBringer: What is above .fv file and how to put it in bios?

Make the dump of BIOS by a hardware programmer.

I don't have a hardware programmer.
Can not solve the problem without it?

Ok, which tool is needed for this?
Attached is a picture of a BIOS chip.

A hardware programmer (e.g. CH341A) and SOP16 flash clip to DIP8.

A have a problem to find SOP16 to DIP8 test clip in my country. Can I use SOP16 to DIP16 test clip and with dupont wire jumpercables connect to CH341a?

I think "yes" but I don't know suitable pinout.

I join the request.
The code can be taken from the firmware file: https://drive.google.com/open?id=18UHxW8...SrArprkYZj
This update file is essentially a tar archive.
AES-NI function is disabled in the "FvDxe.fv" volume, in the DXE driver MpCpu.
There, searching for the sequence "B9 3C 01" we find the following code:
Code:
.text:0000000000002F36                 mov     ecx, 13Ch
.text:0000000000002F3B                 call    RdMSR_res_in_rax
.text:0000000000002F40                 test    al, 1
.text:0000000000002F42                 jnz     short loc_2F62
.text:0000000000002F44                 shr     rbx, 0Eh
.text:0000000000002F48                 mov     ecx, 13Ch
.text:0000000000002F4D                 not     ebx
.text:0000000000002F4F                 mov     dl, bl
.text:0000000000002F51                 xor     dl, al
.text:0000000000002F53                 and     edx, 2
.text:0000000000002F56                 xor     rdx, rax
.text:0000000000002F59                 or      rdx, 1
.text:0000000000002F5D                 call    WrMSR_val_rdx
It's easy to change the code. The question is how to pack it back?
