@Fernando - thanks, but that only applies to Samsung 950, or maybe small range of other disks too correct? How does that system above, offer AHCI BIOS option, with no AHCI rom?
And to further add on that, how would AHCI be loaded/used if using some other regular HDD/SSD without such built in rom in controller? Would that drive then only operate in IDE mode?

Yes that is a very interesting question, the bios already contains even the option to set AHCI in the original BIOS but one thing I noticed is that there is also an Asmedia Sata Controller Module also present in the original BIOS.

Maybe it picks the AHCI from there ?

The SATA slots have different colors and one is specifically for data only which i'm thinking is the AMD controller. Perhaps it loads the ASMEDIA AHCI because data SATA ports don't need a controller initially at boot?
AMD SATA is blue - See in this picture

After adding the ROM I noticed the AMD AHCI ROM loads even before the BIOS post screen. There are definitely improvements with it present, I'm going to keep testing this config for a while.

The AHCI controllers:

IDE ATA/ATAPI Controller:
AMD
PCI\VEN_1002&DEV_4391&SUBSYS_84DD1043

Storage Controller:
ASMEDIA
PCI\VEN_1B21&DEV_0612&SUBSYS_84B71043

@Fernando - thanks, now I understand! I assumed "SataDriver" had the AHCI functionality of modern UEFI Board (like old AHCI oRom), but I never checked into it too much.
I agree, and was about to mention to HumbleModder that AHCI BIOS option, for AMD controller or ASMedia would be separate controller options in the BIOS, and use different controller and colored ports as he mentioned.

@HumbleModder:
To which SATA AHCI Controller (AMD or ASMedia) is your system drive (drive C) connected? Did you recently change the SATA port for the system drive?

I think there is a way after adding microcodes and firmwares to a BIOS, you can hex edit it so, for example, you can still flash a Gigabyte BIOS with the built-in BIOS flashing tool instead of efiflash.

Can you share how I'd do that? I think I'm in the right thread.

Edit: Flash it with QFlash I mean from within the BIOS.

I have an ASUS M5A99FX Pro R2.0 board and want to add PCIE NVME support to it.
I have flashed (I think) the Bios as edited by another user in the BIOS Offers section that supports NVME.
In Win 10, I can successfully see the 512 GB Patriot Scorch M.2 Internal SSD (PCIe 3.0 x 2 NVME 1.2), and have cloned the OS to it (Macrium Reflect).
(Adapter is NFHK Model N-M201, V1.0)

My issue is, the drive does not appear in the BIOS.
Do I need to insert an ID Code for the SSD into the BIOS image so that it will be recognized? Any idea what that code would be?

Thanks in advance,
CleverTwit

Hello!
I'm still new to the BIOs modding scene and am trying to mod the Dell Inspiron 7567 UEFI in order to get access to the [Advanced] settings menu.
I extracted my BIOs from my laptop, shorted Realtek pins 1 and 5, modded descriptor block, and reflashed it to achieve write access.
However, what I couldn't figure out, was how to unlock those menus in the first place.
I tried to use AMIBCU to change Advanced menu's [Default] options to [USER] options, but after flashing the modded BIOS, my laptop black-screened and recovered only after restoring from USB using the recovery options.
However, this recovery only allows the factory exes to be flashed (renamed to rcv), and that makes me redo everything, including the disassembly and shorting of the pins.
I think this has to do with the flags 0xF56 (BIOS Guard), 0x894 (BIOS Lock), and 0x11CF (Flash Signature Override).
So, my question is, how do I go about resolving this issue?
Any help would be appreciated, and thanks in advance!

** P.S. Also, one particular thing I discovered was that AMCBCP (using v5.02 ofc), shows the advanced settings separate from the main options, and as my UEFI BIOs does not, by default, has no 'advanced' tab, (Google "Inspiron 7567 BIOs"), I don't know how I would access it even if I enabled it..
See attached image for reference.

Hello Bios Mod-Pros
The last Days i spend a lot of Time in this Forum - but i dont know if this is the right Way.
Ive got an Notebook with an very "closed" AMI UEFI Bios. The only Problem is, that the i5 CPU gets the CPU Fan at 55 degrees almost at full Power.
There is no Setting in the Bios for that, all is hidden.
So ive Downloaded the newest Bios - but nothing Changed.

Then i found this Place "win-Raid" and the Cloudy Sky went away…
After several Theads - i find the Tool AMIBCP 5.02.0023 - i opened my "downloaded Bios File" (*.bin) and find the right Section
And i changed the TRIP Point 0 form 55c to 71c and the trip Point 1 from 71c to 87c, and Safed the File.

Now what to do? Can i easily run the Updater again?
Or what is the best Way to Edit this two little settings?

Thx for Help!
