I have an asus m5a99x evo r1.0 motherboard. ram ddr3 gskill 16gb 1600mhz. I have a saphire r7 370 video card. The XPG Spectrix S40G 512GT 512GB card. PCI-E PCI Express 3.0 X4 NVME M.2 adapter with the Bios m5a99x evo 1708 version of how to modulate (picture or video) I'm waiting for your detailed help. Best regards

thanks

Welcome everyone - this is my first post here! I was installed the bios modification to my ASUS P8Z77-V LK motherboard and everything went succesfull but... I can't see PATA or PATA SS device on boot list. I'm not sure if I should see it when nvme disk isn't connected to pci plug or everything is ok and i will see it as i connect disk to my motherboard ? I also save image of bios (with AFUWIN) which is currently install then openem in UEFITOOL and i can see the nvme modification. Thank you for your help.

Thats normal
It is only there when the m2 nvme disk is actually connected, (e.x Like with USB Sticks)
if it is not there is nothing to show.

Fernando Thank you very much for teaching me.

Hi all,

Does anyone know why NvmExpressDxe_4.ffs is advised over the combination (NVME.ffs+NvmeINT13.ffs+NvmeSmm.ffs)?
Are there any performance/functional differences?

Thanks.

@Fernando - in regards to above Q - have you ever compared/tested performance or usability of BIOS that did not originally have NVME Compatibility, to insert NvmExpressDxe_4.ffs Vs / Or >> NVME.ffs+NvmeINT13.ffs+NvmeSmm.ffs combo?

Sounds like both may work for some, but not all (unknown, too many untested boards/BIOS), but no matter what >> NvmExpressDxe_4.ffs is the better and safer method to get full NVMe support for old systems with an UEFI BIOS, but without native NVMe support.
Thanks Fernando

@Lost_N_BIOS:
I tried both methods and found, that they work both. According to my experience the insertion of the NvmExpressDxe_4.ffs is the better and safer method to get full NVMe support for old systems with an UEFI BIOS, but without native NVMe support.

to replace the "body" of the NVMe.ffs module by the "body" of the NvmExpressDxe_4.ffs module

Thank you so much Fernando!!!!! My Msi Z87-G45 booted like a charm (less of 10seconds) on my Samsung 970 EVO PLUS
I followed your advice on post #1 and downloaded the moded MSI Z87 G45 Gaming BIOS_E7821_v1.9 by Hancor saw here:

@Alex_BY - Thanks for your report. As you mentioned, that may not be valid test comparison, since you have ME FW disabled
But if it was like that for both tests then should at least be a semi-OK compare I suppose, but I don't know if either use ME at all. If you want to do 100% valid test, ME FW should be there and working, then you will know if this is cause of performance hinder or not.
That last test you and Fernando mentions, I'd like to know about too, if you test please let us know what you find
