Well,about the BIOS Compatibility Support Module...
When i enter BIOS and set the CSM to manual and the boot device to;
Legacy ROM -> system loads the original ROM during startup and boots into Windows, startup time has decreased to almost 20 sec.
UEFI ROM -> system loads the original UEFI rom during startup (and says it cannot boot this device, as expected, as my boot device is not marked as UEFI compatible)
Legacy&UEFI -> system probably loads the two original Legacy and UEFI ROMs, polls and chooses legacy, and boots into Windows, startup time has decreased to almost 20 sec.

When i set CSM to;
Auto -> system immediately loads the inserted ROM with enhanced POST screen and boots into Windows, with increased startup time of 13 sec.

I'm satisfied! But still wonder where that 'legacy' module sits, and if it could be replaced!

I have searched for an AMD AHCI ROM (=LEGACY) module within the latest BIOS for your mainboard and didn't find any.
The missing LEGACY AMD AHCI ROM has been the reason for your long boot time before you inserted the AMD AHCI ROM yourself.
Question:
Did you follow my guide (post #13) inserting the AMD AHCI moule into the CSMCORE file and leaving the original BIOS module named "SataController" untouched? If yes, did you get the same effect (everything works fine and the boot time decreases dramatically)?

#18 RE: [Guide] AMI UEFI BIOS Modding by IMweasel 20.12.2014 00:23

Oh wow thanks for your research, i tried that too but it didn't know what the best approach was properly search for that module.
But what?!? That is extremely weird,considering there is a ;
AMD SB950 controller
6 x SATA 6Gb/s port(s), red
Support Raid 0, 1, 5, 10
...
But there's also the
ASMedia® ASM1061 controller
2 x SATA 6Gb/s port(s), red
2 x eSATA 6Gb/s port(s), red

Did Asus perhaps intentionally not include an AMD AHCI ROM, because they want single-drive configurations to be attached to the ASmedia controller?
And only multiple drive (raid) setups to be attached to the AMD controller?
Would my boot-time also have decreased if i would have used the AMD-RAID controller driver?

Yes, i had already executed the insertion exactly as you explained... and the original BIOS module named "SataController" is untouched.
There was NO decreased boot-time with the original bios and CSM set to auto.
There actually IS a decreased boot-time with the AMD AHCI ROM inserted and CSM set to auto.

I don't think so.

As long as your AMD SATA Controller has been set to "AHCI" (DEV_4391), it will not work with an AMD RAID driver.

Does that mean, that you actually have reflashed the modded BIOS, where you had replaced the "SataController" EFI module by the AMD AHCI ROM module v3.2.2.0?

#20 RE: [Guide] AMI UEFI BIOS Modding by IMweasel 20.12.2014 18:00

Thanks for your insight but, why on earth did Asus not include this module in the first place? It gives a wonderful boost!

No, i have NOT touched the SataController EFI module...I only tinkered the CSMcore as you explained!

You should ask ASUS, not me.
I had a similar problem with my ASUS P8Z77-V, where the ASMedia AHCI ROM was missing.

Thanks for the clarification, which may be useful for other users with a similar problem.

@ all:

Due to the fact, that there is a new AMI Aptio UEFI MMTool v5.0.0.7 available now, which is able to modify all AMI UEFI BIOSes incl the new X99 mainboard ones, I have totally revised my guide, which is layed down in the start post of this thread.

Update of the start post

Changelog:

  • new: complete guide
  • replaced: all pictures

All suggestions for an improvement of the guide are welcome!

Good luck!
Dieter (alias Fernando)

I believe that both MMTools (4.5 & 5) need to be linked at the start of this guide after explaining that 4.5 is for Aptio IV and 5 is for Aptio V. The only reason I'm saying this, is because MMTool v5 is not fully compatible with IV images (cpu microcode etc according to SoniX, lordkag) and so it may lead to problems (preparing an Aptio IV image with MMTool v5 and end-up with a corrupted image without knowing it). It's the same "advice" (not that I have an Aptio V system to test) I gave at the UBU thread.

Other that that, it looks perfectly fine.

thanks to the author for his work.
I'm new to editing the BIOS, and I can not decide for himself.
be saved (CPU microcode) of the BIOS №1 and add (micocode bios#1) to the bios №2.
Thanks!

Decide between what?

If you are unsure regarding the CPU Microcode, I recommend to use the UBU tool (look >here<).

my CPU (ES)
because I want to add microcode from a working version of the BIOS.
UBU tool delete my old cpu-microcode and add new.
THANKS!

Hi,

Was wondering if its safe to not just update device modules but other modules like mousedriver, and core_Dxe and a bunch of the other modules that are in the bios file? For example I have a z87x-ud5h and was looking in the z97-ud5h bios file which looks very similar.

Thanks

Any change of such modules is risky. Furthermore you may not benefit at all by doing it.

Does anyone know how to integrate Gigabyte's 3D BIOS from BIOS Version F14 to the latest BIOS F20?
It was removed from version F16 and onwards.

Here is the F14 BIOS: http://download.gigabyte.ru/bios/mb_bios_x79-ud3_f14.exe
Here is the modded F20 BIOS that I made: https://drive.google.com/file/d/0BwnCOMH...VBUaDhwVGc/view using your UBU Tool.
