Request: Asus P6X58D-E adding NVME support

Refind is working well but would like to add/determine if the NVME capability / hybrid was possible with 803 bios for this mobo

did you get any anwser??.. for two weeks, i try to get a Crucial P5 Plus to work with this MoBo with no success… even my native win10 dont boot with the nvme connected… it crashes at start up… cant find a way… tried Clover, duet, … no solution

Lets get something straight… a PCIe M.2 adaptor with an MVMe drive on it, will be seen in win7 up OS on older motherboards as a storage device, mods or drivers apart from it.
So your telling us that your motherboard P6X58D-E only with a GPU on slot1 and the adaptor on any adjacent slots (2nd blue or white) will prevent the legacy OS (presumably on a SATA HDD or SSD) from booting, is this correct? Also presumably you already tested the insertion of the same conjunction of adapter/nvme drive in a another motherboard.

EDIT: 1rst vid is concerning clover, sry dont gonna loose time with that, i had my days in hackintosh…not anymore, ask help to others.
Second point, why and you should not, booting from the 2 sata ports from Marvell???
Third point…win10lite wtf is that… you like modified OS isos…im out also in here.

Do you have a sata AHCI disc with an official OS to boot from and only with GPU and adapter/nvme on white slot, also audio card off, this is the test to do on your motherboard and the NVMe drive must show in device manager and in disc manager, as a storage device, no driver needed, thats it, it works or not, then you can start thinking in NVMe mod like you asked in the other thread.

i tested in a newer mobo, win10, and it runs well… on my old pc with mobo P6X58D-E, win10 lite (spectre), my sistem dont boot… i tryied with aioboot from a tutorial in the forun, with win10 downloaded from wintool, and is the same thing…
usb3.0 drivers disabled, achi enabled… my windows 7 starts but dont see the disk
here is the result

@MeatWar thanks for your support… my idea is not change my system… is just to get the system work plus the nvme/pci-e… i want tho install a basic music studio in the nvme, so i want to keep the audio card… i use win 10 lite (mod win) cause i dont connect internet, it is just to run music apps… dont use windows apps at all… so if there is nothing that i can config in bios to make it run, perhaps i have to go to mod nvme as you said… is there some good and easy tutorial?

There is no easy “tutorial”, but all that is needed is on the same thread you posted yesterday and asked a user.
I said take out audio card to debug/test only, not permanently.

I say again you need a TEST before considering NVMe bios mod, i repeat for the LAST time: “…NVMe drive must show in device manager and in disc manager, as a storage device.”
I know that you already tested the adaptor in another motherboard…

EDIT: Then the adaptor/motherboard dislikes them selves or a resource allocation conflict by the motherboard. Both PCIex16_2/3 fail?
Specific drivers are not needed for tests, the MS OOBox driver is enough for testing…

well… take off audio card… tested on fresh win10 instalation (win10 downloaded from wintool)… crashes at booting with nvme connected… in my win7 that boot but don’t see the nvme, i installed the Crucial P5 plus driver, and windows crash… when boot it still don’t see the nvme… so i installed the microsoft nvme hot fixes for win7 (k2990941 and k3087873) and now the win7 freezes at boot too, with the nvme connected… i copied the drivers from the win10 that i can run the nvme to my win10 and freezes at booting too… or the drivers aren’t compatible with the MoBo or it’s some bios config

both PCIe fails… did the nvme have to be a special config, like mbr or gpt, or fat32 or nfts, or primary partition???

NVMe booting requires x64, NTFS file system on GPT partition, but this is irrelevant for testing, in device manager or disc management, it can even be a RAW disk.
As i said already, any machine even without boot support for NVMe and with a modern OS, 7 up has to see the disc in OS only (not bios), in any state.
You can find user reports of using NVMe discs on cheap adaptors as storage even in older motherboards. Again you tested on another motherboard then yours doesnt like the brand/model, compatibility, the P5…who knows. Specific bios config on specific (yours) motherboard i cannot help you… not without a live one here with me, but for straight storage i dont see anything particularly to set on the mb.

EDIT: That “machine check exception” is very vaste… primary due to hw issues, resource allocation, ram errors, disk i/o… only by the message is not easy to pin point.
Dont give up, good luck.

thanks for your support anyway… i don’t now what more can i do… below a win10 screen crash, if it can help.
