@hancor Thank you very much, Ill keep you posted

@hancor Many tanks. Ive downloaded your Z87HL.rom and also have two options generated by the tools in the post (#1 | [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS)
Ive followed the steps in the link and have read #17.
Ive tried to flash your Z87HL.ROM. I have used the afudos.exe Z87KHL.ROM /P /B /N /X COMMAND in FreeDOS. As in the post the command was afudos mod.rom /GAN ? and having looked at the documentation for the afudos I couldn't find what this command meant ?
In any event. In the attempted flash, the flowing was the result
Reading flash .. done
-ME Data Size checking . ok
-FFS checksums ..... ok
1e - Error: Secure Flash function is not supported on this file

I tried using the eazy flash option in the bios, and it said the file file format was wrong as it needed to be .CAP ... I altered it on the USB, and tried top see if this worked. I had the same error.
I also tried the above with the two different options made with different tools in the guidance notes and had similar errors.

The latest Driver downloaded from asus is Z87-KASUS-1402.CAP and it is 8194kb. When I mod this it ends up being the same size which is good. Your file is 8192kb. .. Im not sure what to do next. I can send you both of the mod files to review the mods ? Is this possible ? Sorry for the long winded message .. Off to bed now Long Day
Id be grateful of any other options I could attempt ? Kind Regards

@hancor
oK Ive managed to use your mod file Z87KHL.rom and to use the afudos.exe Z87KHL.rom /GAN and then the results are :-
Reading Flash .. done
-Me data size checking . ok
Erasing all block ... done
Updating All Block .. done
Verifying All block .. done
C;\>_
Not sure whet to do now .. how do I flash the bios and update it from here ?

Please advise sorry for all the silly questions this is all new to me. Best

@Grandmasterlee

type exit hit enter
remove the USB drive
reboot
hit del on reboot
enter bios
load setup defaults
reboot
enter your favorite settings
for NVMe booting set CSM to DISABLED
set OS to OTHER
reboot
reload WINDOZE
and yer good to go

Cheers

@hancor Thanks for guidance this morning.
I've followed your steps above, ie exit, remove usb, hit the Del and entered the bios screen, the name of the bios is still the same as it was prior to this flash ? ie Z87-K BIOS VERSION :1402 is this correct ?
load setup defaults (f5) and set csm to disabled
And Im now loading w10 onto the PCIe slot which is AWSOME !

So impressed with this forum and the support many thanks Hancor yr a genius

How do I donate is this at the Top ?

Best Regards

@Grandmasterlee

Yes the bios is numerically the same version 1402 but of course it is modded; otherwise you wouldn't be booting from the NVMe drive.

If you download the program HWINFO it will tell you the microcode version to verify it is updated.
