Hi,
I will upgrade my home server (Z77+i3 3225) to latest Z170+i3 6100T.
The motherboard is "Asrock Z170M Extreme 4", and its lastest BIOS is realy new : v1.40 1/20/2016
Even if this BIOS is new, all OROM/EFI inside it already have avaible updates ...

Here is what's inside v1.40 :




And here is what I have after updating EFI with UBU and OROM manualy with UEFITool.exe :



OROM Vbios stays at 1020, everything else is upgraded.


Do you think it is still "safe" to replace current OROM/EFI in such recent BIOS?

Thanks

This is absolutely normal. The mainboard manufacturers usually do not update the OROM/EFI modules, when they offer a new BIOS version.
The latest BIOS 2.50 dated 10/19/2015 for my ASRock Z97 Extreme6 still contains the very old Intel RAID ROM/EFI RaidDriver modules v13.0.0.2075.

Why do you think, that it would not be "safe" to update the standard OROM/EFI modules yourself (as long as you make sure, that the newer modules match your system)?

ok ok

One more question : as you can see I haven't updated the OROM Vbios 1020 but the EFI yes.
Is it a problem?

I have downloaded the bios for the Z170 Extreme 4 (mine is Z170M Extreme 4) and it has a 1040 Vbios.
Do you think I could exctract 1040 Vbios and use it to replace my 1020?

Thanks again for your help.

@ propergol:

There is also a newer uCode, version 74 which probably fixes the recently announced SKL crash erratum. It should be available with UBU update 6. Also, the latest VBIOS is 9.0.1034 but unless you have CSM enabled, updating it is not beneficial in any way as it's not used.

SoniX needs to verify that but to my knowledge that's how UBU works. The number doesn't matter as long as you have the correct one for the cpu you are using. The platform you are interested at is 36, the other 22 something else I suppose (QS cpu or similar). There shouldn't be any issue but I would wait for SoniX to assure you.

Regarding the microcode I am not sure,
Is it correct or did I miss something (only 1 line vs 3 lines)?

Hello! :)
Everything seems to be as usual pairwise compatible - SNB=IVB, HSW=BDW and SKL=KBL.
We are waiting for the GOP driver, it is likely to have 9.5.xxxx version and is compatible with SKL and KBL. ;)

That's the signon message, should be ignored, as OEMs can and will put just about everything in there. The hex version from VBT structure should be trusted, not sure if it can be changed with BMP. For the VBT version, you can quickly check with "efivbt" or manually with <this guide>. For instance, VBIOS 9.0.1028 should report SKL_1028_VBT196, as in Platform - ROM Version - VBT Version.

Version VBT C8 = 2.00 in OROMs 1031-1037 .
Perhaps Intel will not change the version like HSW-BDW (5.0.xxxx -> 5.5.xxxx) and leave everything as it is 9.0.xxxx. But perhaps the changes. Everything is possible, wait and see everything in the next versions. ;)
