You're welcome @Fernando! I still get redirected to homepage? At this line, last link >> DUET-USB Boot Method" (the related guides written by our Forum members noInk resp. mireque can be found >here<, >here< and >here<)<< Last link
Redirects to #msg34142 I tried to find correct link or thread for you, but couldn't find it due to limited search controls

Not for me, and both of the links you gave in above thread now goes to an error page saying
"An error occurred! The page you were looking for does not exist or you do not have the right to access this page. Back to Forum overview "


However, the same exact link you gave above twice, as the one on the first page one still gives me the redirect, strange behavior!


Maybe it's just me? I only mentioned it because I thought it was a broken link, maybe old URL format before a forum update or something, if it's working for most everyone else then we can safely ignore and you can delete these posts if you want
I thought maybe it's an IE11 issue, but tested in firefox and get the same, error with above links and redirect when clicking that same link on page one. Acutally, in firefox, not signed in, if I click either link above it give me the error occurred page and tells me I have to sign in
All ad-blocking and such disabled always for me on this site too, so it's none of that causing it.

The table below summarizes high-level differences between the basic NVMe and AHCI device interfaces:



@Fernando
Hi, i have question on AHCI interface. Can SATA 3 6gbps actually utilize MSI-X? From how i look at this chart it looks like a definite no. I downloaded the software and enabled Nvidia GTX 1080 Ti to MSI-X but not sure about AHCI devices like SATA ssds and HDD. Thank Fernando

@lime:
What have your questions to do with the topic of this thread?

---

@lime:
NvmExpressDxe has no support for interrupts (including MSI-X), it's always polling the completion queue.

Note that various sources suggest that MSI-X is slower than polling because NVMe has extremely low latency.

OS drivers might have support for MSI-X, but unfortunately I have no information on how to disable it.

@Ethaniel:
Uhm okay, would you know if SATA also supports MSI-X too? Sorry, way off topic.
I did not know NVMe is slower if enabled possibly.
There is a guide on guru3d that describes how to execute MSI-X for certain devices. Thanks

Hello, I have been trying to mod my old Lenovo Thinkstation's AMI bios to boot from Samsung NVME 970 EVO without success.

I followed the "How to get full NVMe support for all Systems with an AMI UEFI BIOS" guide by Fernando to the best of my abilities but I'm not sure why it's not working.
Maybe I'm on a wild goose chase and it is not even possible? I'd really appreciate some help if possible. Here are the details:
(Note: I did get my machine to boot into windows 10 on NVMe using the clover USB method, but would like to boot via bios mod (if possible))

(1) My PC is a Lenovo Thinkstation S30 with bios updated recently (2017) from Lenovo website: https://support.lenovo.com/gb/en/downloads/ds028141
(2) On the Lenovo website it says "Flash UEFI BIOS update" so I have been assuming it would be possible to mod this UEFI bios?
(3) I used the recommended tools to mod the original bios and insert the NvmExpressDxe_4.ffs driver and managed to flash the new modded bios without any errors.
(4) This modded rom file cannot be attached because it's over limit so I uploaded images. Could someone please look at it to see if it is inserted in the correct place?

I have followed all the steps in the main guide (How to get full NVMe support for all Systems with an AMI UEFI BIOS) on the setting of the bios but I cannot get the PC to boot. Once windows
has copied all the files ready to install and once the PC reboots than it fails to finish the windows installation process- no boot device found. I cannot see anything in the modded bios which says "Windows Boot Manager" or anything else so I cannot select the NVMe ssd in the primary boot up options list in the modded bios.

Windows 10 starts to install properly (created by rufus as in guide) and finds the NVMe ssd (installed on PCIe adapter) but cannot finish the windows install after the first reboot. My bios cannot find the NVMe boot drive.

Thank you very much for doing a great job on this forum! :-)

Thanks for your quick reply Fernando and apologies for posting this in the wrong section. I agree, hopefully this will help others.

Regarding your comment: "It is to be checked, whether the flashing of the modded BIOS was really successful" that is a very good point. How would I go about checking this?
* I just assumed flashing had worked properly because the NVMe ssd had been detected by windows during installation, which I did using the USB created by Rufus.
* I have played around with the bios settings as in the main OP guide. Nothing seems to help.
* The "Windows Boot Manager" comment is very interesting and I will double check the EFI boot partition to make sure it has been done properly - thank you.

Answers:
(1) PATA option is not listed anywhere (I will upload screen shots of bios later)
(2) Yes, I selected GPT partiton scheme in rufus (exactly as in OP)
(3) Yes, fast boot (no secure boot option) had been disabled in the bios
(4) Yes, all other HDD's were unplugged before I started installing windows
(5) Yes, all existing partitions of the NVMe were deleted and recreated by the OS during installation.

Thanks again for your reply.

My PC SYSTEM:
Lenovo Thinkstation S30
CPU: E-5 2690 (8 core)
Graphics: MSI Armor Radeon RX 570 (8gb)
Memory: 32GB Samsung (ddr3)
HDD: Samsung NVMe 970 EVO and SSD 860 EVO (sata)
OS: Windows 10 Pro

UBU utility on the modded bios rom shows as in the photos attached:

Hello everyone I need support
I have a motherboard "ASUS P8-Z77-M PRO" .
I installed an ssd m.2 NVMe "Samsung EVO 970 NVMe M.2 250GB" via adapter card pcie "Silverstone ECM21".
I followed the whole procedure to modify my "BIOS" to add module "NvmExpressDxE"
Windows 10 recognizes the ssd NVMe only as storage, but I can not get it to appear in the BIOS menu "Windows Boot Manager" or "PSATA"
I install windows 10 clean from usb boot, I recognize the NVMe drive and install windows 10 completely, all right. But in the BIOS boot menu I do not see "Windows Boot Manager" or "PSATA"

What could I do wrong?
Can you help me
Thank you
