@all:
The UBU Guide (= start post of >this< thread) is temporarily not available.
While trying to upload some new pictures I got the message, that "something went terribly wrong", with the result, that the complete text of the UBU guide inclusive the title got lost.
When you follow the link, you will only see the previously attached pictures.
I have immediately contacted our hoster and hope, that the start post with the UBU Guide can/will be restored very soon.

I am sorry for any inconvenience!

EDIT: >Here< is the download link to the currently latest UBU version v1.70.b16-Dev_without-MMTool.

UPDATE: The UBU Guide (= start post of >this< thread) is online again!

@Lost_N_BIOS:
Thank you for your tip, which is very useful for all Forum members, which are running into the same situation as me yesterday.
Fortunately Mods and Admins are able to recover any previous version of a certain post by using their enhanced editing rights, but I didn't know how to do it until now (5 years after having started this Forum! ).

@SoniX:
Your latest UBU version v1.70.b16 is a big step forward, because it now offers the update of Intel LAN Option ROMs and EFI UNDI modules. Thank yo very much for having made this option available!

While trying to update the UBU Guide, I have done some tests of this new option and found, that there seems to be a mistake within your script regarding the update of the BIOS LAN modules for the Intel Ethernet i218 chips.
The tests were done with the attached BIOS v2.80 for the ASRock Z97 Extreme6, which has an Intel Ethernet i218 chip.

Here you can see the Intel LAN modules, which had been detected by the UBU tool and what happens after having chosen the "correct" Choice 1:


And this happens after having chosen the "wrong" Choice 2:

@SoniX:
Thanks for your reply and the statement, that both update options are possible for Intel i218 LAN chips, which have the DeviceID DEV_1502.

Nevertheless there are a few things, which are still not absolutely clear for me:

1. The ASRock Z97 Extreme has 2 LAN Adapters from 2 different manufacturers on-board, but only 1 single LAN chip from Intel (the i218 one).
   According to the UBU tool the original test BIOS Z97Ex62.70 contains the following BIOS modules for the mainboard's on-board Intel i218 LAN chip:
   • EFI Intel PRO/1000 UNDI v6.1.14 and
   • OROM Intel Boot Agent GE v1.5.50,
   but they are replaced by the following modules, when I choose the correct update option "1" (designed for BIOSes with "only 1 chip 82579/i217/i218"):
   • Intel EFI Gigabit UNDI v0.0.19 and
   • OROM Intel Boot Agent CL v0.1.13.
   Neither the module names nor their version numbers seem to match for me (contrary to the results I got when having chosen the "wrong" update option "2", which has been designed for Intel i210/i211/i350 chips).
   I always thought, that an Intel LAN EFI PRO/1000 UNDI module should be replaced by an Intel PRO/1000 module and an Intel LAN Option ROM Boot Agent GE should be replaced by an Intel ROM, which belongs to the same Boot Agent GE series.
   Have I been wrong regarding this point?
2. What means the Intel LAN update choice option "--", which obviously has been designed for BIOSes with 2 different Intel LAN chips?
   After having chosen the option "1", I have tried to repeat the update by choosing the option "2" (and vice versa), but this didn't change anything regarding the result of the first chosen update option.
3. When I had chosen just the "wrong" Intel LAN update option "2", the Intel LAN EFI PRO/1000 UNDI module has been successfully updated from v6.1.14 to v6.6.04 and the Intel LAN OROM Boot Agent GE from v1.5.50 to v1.5.62.
   This verifies, that the UBU tool definitively contains these 2 Intel LAN module versions, but why are they not listed by the UBU tool as being available?
