Aurora R4, boot from PCIe?

Hi all,

I have an AURORA R4, and I'm planning to upgrade my ssd. Actually I'm using a 840 evo, and I wanted to upgrade to an nvme ssd. My motherboard is the x79 model with the i7-4820k. I know that this MB doesn't have an m.2 slot, so I wanted to use an nvme ssd + pci-e adapter combo. Then my question is: does this MB support boot OS from a PCIe device? I wouldn't buy it, and use it just as a storage.

Thanks you

Re: Aurora-R4, boot from PCIe?

IIRC, the Aurora-R4 is UEFI-based, so it should work.

I don't know that anyone has ever verified it here though. Let us know how it goes. 

I don't expect it to be particularly easy so if it's not working, don't give-up too early.

I have read that most pc's (especially Dell) wont boot from nvme while attached to a pcie card adapter. Will function as extra storage but that's about it.

Years ago, back when XPS models first started shipping with (on motherboard) PCIe/NVMe slots and SSDs ...

Some knowledgeable users noticed lower-than-expected transfer rates . The consensus was that it was due to minimal PCIe lanes used on those early implementations.

They removed their PCIe/NVMe SSDs from the MB and inserted into generic PCIe x4 Addin-cards. The SSDs booted and worked fine (and even a bit faster).

Re: Aurora-R4, boot from PCIe?

This was just based on my research, specifically regarding the aurora r7.

I am far from a computer wiz, but still quite confident. The info I found when I was looking into it was very off putting, and I simply decided...nope...lol

Re: Aurora-R4, boot from PCIe?

Thanks for the answers and sorry for the late reply.

So youre saying that the minimal required to boot from pci is to have a UEFI based motherboard? I thoght that boot form pci-e is a dedicated option, so it change from bios to bios, even if it is UEFI.

 

Anyway, I will wait black friday to buy all the stuff, then I will let you know Smiley Happy

Re: Aurora-R4, boot from PCIe?

I've also heard about that. Not for DELL in particular, but for those motherboards that doesn't have this option natively enabled in the BIOS. This is the reason why I've asked here. I would't buy it, and then find out that I can use it just as secondary storage.

But hey, in case that it don't work, I will return it back and switch it with a classic sata drive.

Re: Aurora-R4, boot from PCIe?

I saw a guide in the link below that you need to mod your BIOS to allow it to natively boot onto NVME via NVME PCIe adaptor https://www.win-raid.com/t871f50-Guide-How-to-get-full-NVMe-support-for-all-Systems-with-an-AMI-UEFI... I followed the instruction on modding downloaded A11 bios but I am hesitant to apply the mod at the moment as my Windows 10 is setup in Secure Boot.

I plan on getting the following though

NVME drive I plan is - Adata XPG SX8200 Pro
NVME PCIe x16 adaptor - https://www.lazada.com.ph/products/magideal-nvme-m2-to-pcie-adapter-pci-express-x16-to-m2-expansion-...

Re: Aurora-R4, boot from PCIe?

I have an Aurora R4 motherboard (x79) with BIOS revision A11. I am booting off a single SATA SSD (Samsung 840 Evo 1tb) via Windows 10 1903 in Secure Boot.

I am provisioning this when I upgrade my SSD to an nVME drive that I intend to do a fresh install of Windows 10 (which I can disable Secure Boot, Fast Boot, CSM later)

UPDATE I was able to flash my modded Aurora R4 A11 BIOS using AFUWIN for APTIO4 (https://ami.com/en/?Aptio_4_AMI_Firmware_Update_Utility.zip - under \afuwin\64\afuwin64\AfuWin64\AFUWINGUIx64.EXE)

I just programmed the Main BIOS Image, checked Do Not Check ROM ID and Restart After Programming

So far, I am still able to boot (in Secure Boot) Windows 10 using my SATA SSD.

I have an Aurora R4 motherboard (x79) with BIOS revision A11 and have modded BIOS. I am booting off a single SATA SSD (Samsung 840 Evo 1tb) on Windows 10 x64 (1903) in Secure Boot.

Will post an update once I have an NVME drive to do a fresh install of Windows and boot directly off of it.
