[Request] getting NVME support for GA-B85M-DS3H rev 1.1

Hi, found this forum thread and wanted to ask if its possible to get my motherboard, a GA-B85M-DS3H (rev. 1.1) a bios modification so that it can accept NVME. heres the bios (right now my MB is at f6, the new BIOS would be at f8) GA-B85M-DS3H (rev. 1.1)

But just to confirm, would it work with a PCIE x1 to M.2 adapter? i bough one and i connected it, light turns on but the PC nor the BIOS recognize it, so i wanted to know if the BIOS modification would work, or if its necessary, as i just want to use the NVME drive as storage, not boot.

I appreciate the help, good day.

Good morning
I looked at the uefitool bios F8 and it does not have “dxe NVME” so obviously it cannot recognize the SSD on a PCIe card. Try adding the driver “NvmExpressDxe_5.ffs” and flash the bios. I know the flashing procedure on ASUS but not on yours. keep us in touch.

Adding the DXE driver is only necessary if you want to boot from the device, not for an additional drive for data.

Did you just put in the adapter or adapter with NVMe disk?

The adapter itself doesn’t have any logic so it wont show up anywhere.

PCIe x1 slot would be attached to chipset, meaning PCIe gen2 x 1 => ~500MB/s
That’s the same as SATA gen3, so why the effort?

No, i connected it with the NVME properly installed, light turns on but BIOS nor windows recognize it, could it be that there was a windows OS installed there, and that’s why it wont recognized it? because it needs to be empty?

I just had an extra NVME that im not using and i wanted to use it there, my other SATA drives ports are full as well so i wanted to try with PCIE.

Windows 7 will need drivers for NVMe, later versions should recognize a properly installed NVMe disk at least in device manager.

I got Windows 10 but still nothing…

Could it be in this case the NVME then? i have one with b+m and the adapter is for m, could that be the problem? i read that a m port could still read a b+m m.2, but maybe im wrong…

im trying to find right now if i can maybe install drivers somewhere…

What type is the m2 disk?

its a b+m type, 250GB, LITE-on brand


Sorry, 256GB, its and old NVME from a laptop i had, its from 2016

A ‘precise type’ description would mean more than the brand and ’ from an old laptop’: The letter / number combination a vendor uses to mark its articles!

‘from 2016’ might as well be an SATA M2 disk, but you have to check yourself.

Not enough patience on my side to ask the same question several times. I’m out of it at this point, good luck!

I understand, sorry for not being more precise.

To answer the questions, its a LITEON L8H-256V2G-HP, which according to the specs its a SATA M.2 disk, not nvme.

Your problem is in the adapter, the slot connected or the M.2 SATA disk is death.
Test the set in another motherboard or slot, those x1 adapters can be plugged to any PCIe slot since x16 to x1.

Bios recognition or bios mods is not the issue here neither any OS, since this kind of disk is treated as a standard storage disk and no specific drivers needed.

As this is a disk on an adapter and not on a M.2 motherboard slot itself, usually in this old boards the disk is not seen in storage devices or in boot manager.
In boot manager entries only after an OS installation, it may show a boot entry.

Thats it, no more miracles here.

EDIT: Correct lfb6… he said it has 2 adapters available.
Presumably he knows what to do right…eheheh

A SATA disk never will work in an PCIe adapter for NVMe disks.
Some of these adapters have an sata controller in addition, but possibly not the ones for x1 slots.


yeah, i guess that’s my problem, in the product page it only says NVMe and not m.2 SATA, so it was an oversight on my part for not checking what drive type i had.

Either way, i appreciate the help and thank you for your time, nest time ill be more throughout with what to buy

An NVMe adapter is just an extension of a PCIe slot, the memory controller on the disk is directly connetcted to the PCIe lanes and has its own protocol.

Foa an sata m2 disk you need an sata controller which has on one end an SATA interface which connects to the memory controller on the physical disk and on the other side a PCIe interface.

Unfortunately were the codings of the m2 port not followed precisely, there’s some overlap so that you can insert wrong disks and for some- mostly (?) notebook- M2 slots there’s both SATA and NVMe possible…

1 TB NVMe M2 disks are down to ~50$…
