Can any one confirm that this works?? Im gone make a new pc with the asus mobo mentioned here so i like to know if this realy works before i install the modded bios, oh and where put the ssd? In the msata/wifi slot or in the pcie slot with adapter
Lastly, you need to set CSM (Compatibility Support Module) = DISABLED otherwise your BIOS/UEFI won’t ‘see’ the WINDOWS BOOT MANAGER in the boot tab of your BIOS/UEFI. Furthermore, you’ll need to convert ALL your MBR drives to GPT (GUI Partition Table) drives after you’ve backed them up.
Sometimes you just need to do a little further reading and follow the (DESTRUCTIONS) INSTRUCTIONS to the LETTER.
Ok i wait for the new pc in a few years then i have it stock, due tonmy knowledge i dont dare to take the risk if i read what i have to do just to gain e few secs on startup and work, thanks for your advices all
i sitll dont know if im gone instal the modded BIS or not, what are the pro’s and contra’s for this, i only see pro’s nothing else but im just afraid to mess up the BIOS, still reading the page on my manual to EZ-flash bios
Thanks for the update, no isuees with this new bios, the fact seems a bit more stable than original Asus 1903, I had some issues with my I7 3770K oc to 4.6 after Mircosot security patch for Melttdown and my OC become unestable, with RPCS3 emulator and I had some Whea log error but with this bios these errors are gone.
Thanks for the modified bios. I was able to flash the bios with the modified version using the USB ROG connect method per instructions.
I’m currently running into an issue when trying to install Windows 10. At the install screen, it could not be installed on the NVME drive. The message says, “Windows cannot be installed to this disk. This computer’s hardware may not support booting to this disk. Ensure that the disk’s controller is enabled in the computer’s BIOS menu.” I have tried to disable the CSM, but after restarting it does not post. I had to use clear CMOS button to post. Please let me know if I’m missing some step.

What kind of graphics card are you using? All your core drivers need to be .efi driver enabled to boot into the UEFI environment.
Furthermore, any MBR type drives need to be converted to GPT (GUI Partition Table); as MBR formatted drives don’t play nice in the UEFI environment. Also unhook all your other current drives except the NVMe to do the first install. You can rehook up your other GPT drives later.
Additionally, ensure that your version of Windows ISO is the correct one.
NOTE From the FAQs on to burn ISOs via Rufus software:
“If you are using a Windows ISO that can be dual booted in UEFI or BIOS mode, you may find that the USB created by Rufus does not preserve the dual UEFI+BIOS boot feature.
Especially, the Windows 8 or later installation ISOs, that support both UEFI and BIOS boot, will be converted to either one or the other mode, depending on the option you selected under Partition scheme and Target type: If you select MBR and BIOS or UEFI-CSM, the USB will be bootable in BIOS-mode only (even on UEFI systems), and if you select GPT then the USB will be bootable in UEFI mode only (and not bootable on a BIOS system at all).
This is done to avoid confusion, as it can be difficult for non-expert users to know whether they actually booted in UEFI or BIOS mode when a USB Flash Drive can be booted in both modes, and installation is meant to be a one-off operation, targeting a very specific machine and boot mode. You probably don’t want to go through a full Windows installation, only to realize that it was installed in BIOS mode when all you really wanted was UEFI mode.
By ensuring that only one or the other can be used for Windows installation, there is no room for error with regards to which mode was used.”
I would just like to thank the OP for this mod. I am using it successfully for some months now with windows 10 UEFI mode.
Only problem I have found is when you set up power button to go to sleep and not shutdown, it works but if you wake from sleep from power button and not mouse keyboard then power buttons stops working. You have to use the sleep from start menu after that to make power button work for sleep again.
If I wake the system from mouse or keyboard problem does not appear.
I did try to install different versions of intel me drivers (from 11.x that windows installs down to 8.1x) but it does not solve this. Anyway it’s just a minor problem and someone that uses power button for power off will never see it.
Again thank you for the mod. Hope to see newer ones.
