Try the 4701 mod bios

---

Hello All

After reading many forum topics, I decide to try to put M.2 Samsung 970 Evo Plus 500GB in my P9X79 plain motherboard (NOT PRO or DELUXE)

I was able to do all of the steps, like use UBU to update the uC, add the NvmExpressDxe_4.ffs to the ASUS bios 4801 (BETA) from the site, using the mmtool to insert the module / join everything and using USB Flashback to update it.

Everything went OK, but I am not able to boot from the M.2 Disk at all. I try to follow all the hits in the forum, like disable CSM in the bios, but I do not know if I should see the disk inside the BIOS like the other ones when they are connected or not. The bios power up simple does not detect any drive.

I also try the P9x79 MOD bios in the forum with no success, because I could had some problems in my bios built.

I use the CMOS switch to clear the BIOS and always load defaults after bios update.

I use rufus in GPT mode to create a WINDOWS 10 PRO USB boot disk and I was able to see the Samsung disk and Install windows on it. I only have the M.2 installed in the motherboard for now.

After reboot, the disk does not appear as visible drive in the motherboard and it does not boot. I install windows 10 Pro in USB disk with WintoUSB and I was able to start the PC. I can see the drive inside disk manager and everything seems to be ok.

I am using NVIDIA GTX 650OC in PCIEXP16_1 and I try to plug the M.2 adapter in both PCIEX16_2 and PCIEX16_3 (8X) but the M.2 Disk does not boot in any of them

Do I need bifurcation? If yes, any help for this one.

Should I see the disk inside BIOS?

Should I try to put some PCI old graphics card to see if it any problem with the NVIDIA card?

Missing something? ;)

Another different question. I had two 2.5" SDD Samsung 840 in Raid 0 in the system. After all of these modifications, I will be able to use them in raid 0 again as a storage drive?

After having successfully flashed an NVMe modded BIOS you should see a device named "PATA" or "PATA_SS" within the "BOOT" section of the BIOS.

Yeap, basically I never did an BIOS update.

Everything is working fine now.

I was using an older 4GB USB 2.0 Flash, but for some reason it was not working. Switch to one from Scandisk and it worked fined.

Thank you for your support.

I will try to the raid now ;)

Wow! It works! thank you so much!

I'm having issues trying to flash my BIOS using Flashback. I've tried several USB keys, from 8GB to 512MB in FAT16 or FAT32 and every time I get the same result. The blue light flashes a couple of times and then just stays on steady blue.

Has anyone any pointers, I've used Flashback before and it's a fairly straight forward process, but am I missing something obvious?

Thanks in advance.

If u used the feature before...then im not gone say that u do know the right name file for the *CAP file.
Other than that and after a bunch of USB keys used...i can only advise a cold reset to the bios or u can have hw failure.

Thanks MeatWar. I appreciate it has to be the correct .cap name, I'm using the file in post #2 and I haven't amended it from 'P9X79.CAP' I'm assuming this is correct?

I've ordered an 'old' USB 4GB stick and I'm hoping I might have some luck with it.

Asus BRenamer tool will give u the correct name, but yes it is P9X79.CAP for this model only.

Why is the flashing an issue ? Flash worked fine for me the first time and a few times after. Just flash like a bios recovery.

Some USB Sticks just have issue @chuckbam
@frogone - Smaller and older is better, 128KB-2GB, format via windows right click quick format to FAT or FAT32
Newer or larger USB Sticks >> "Sometimes" if you partition down to 1GB FAT or 1GB FAT32 that will help, sometimes lager than that is OK too, but best to stick with trying out 1GB down-format when having USB compatibility issues.
USB 2.0 also best, but some USB 3 work OK too. Dig around in your attic or basement, or old desk drawers etc, you'll surely find some actual old USB sticks hiding from you

Thanks for the input. @Lost_N_BIOS I managed to find my trusty 'Viking Interworks' 512mb USB 2.0 stick, I formatted it FAT32 unfortunately with the same result, but I had tried this stick before. I'll try another couple of USB sticks when I get my hands on them.

I'm assuming it's not a security issue like using EZFlash2? I'm also assuming it's OK to have peripherals installed in the other USB ports etc? Some videos online just show the board alone being flashed.
