Update Win7x86 for USB3/nvme? Redux

Trying a Samsung 980 produced the same results: Windows7x64 would install (after the F8 signature bypass) and Windows7x86 would not. The nvme drive partitions are presented at the "Where do ypu want to install Windows?" screen for the x64 install, but not for the x86 install. In each case a USB drive was built using Integrate7 v3.80 and Rufus.
And so, has anyone installed x86 on an m.2 nvme drive, and if so, which drive and which drivers? I have tried two now with zero success. I am beginning to think that no one has, and my original post cannot be answered.

Small side question, why do you want to even install x86? In this day and age, it's difficult to find a good reason not to use x64.
Many programs (including Windows itself) are no longer made in x86

Legacy reasons. I have between 15-20 older programs (16 bit) which will not run on x64. I don't want to rewrite them to be ported over to a 64 bit Windows (whenever I mod something, it winds up being rewritten!).
I sometimes think that a small mod of some sort could be made to x64 so as to get it to run 16 bit programs; the tiniest mod -- adding one declarative line to a .inf file -- extended the early Intel graphics driver to 10th gen ( possibly further) cpus.

A better option would be to install 16 bit programs in a virtual machine running and older 32 bits Windows, or use DosBox if your programs are DOS-based instead, if updating to a newer version is impractical.

Enabling running 16 bit code on x64 is not just a "tiny mod" disabled by a setting. It's a whole subsystem enabling emulation of whole system calls and a full library of system function allowing programs to run unmolested by the newer system, and that's only for Win3x programs. Every single 64 bits version of Windows includes this for allow run of 32 bits program, but MS deliverately omited that for 16 bit ones, as the complexity of Windows would have increased and those programs were already rare anyway. So no chance of a native run other than usage of x86 Windows (which is also on the way out, BTW).

Install to a normal SATA drive then clone that to the NVMe. After that flip the bird to Windows. LOL Been there done that...

There are two necessary Windows updates that need to be installed for NVMe functionality in Windows 7. I don't remember their names. You can slipstream those or once again bypass driver signature checking in Safe Mode and install. Remember, that driver signature bypass is once per boot. Another glorious pile of crap from MS to do that signature check crap. Really pissed me off when I discovered that bit of nonsense. "Oh, it's all about security." No, it's not, your OS is still as vulnerable as ever. It's about control.

NTLite or DISM can slipstream. I have used Ventoy for booting or Win2USB.

Install the two NVMe updates in the regular SATA drive first otherwise you may not be able to boot the NVMe.

The two updates are; KB3087873 and KB2990941. Not sure if there are 32 bit versions.

Scroll down to Microsoft’s NVMe Hotfixes for Win7/W2k8 R2. It appears there are 32 bit updates.

Ok: bad news and good news.
Bad news first.
I tried an Intel 670P M2.NVME using the nvme drivers downloaded from Intel: v4.4.0.1003 (5/16/2019).
Integrate7 v3.8 did not work altho, as usual, it added the USB3 drivers to the Windows DVD files and produced a working .iso which Rufus filled a Usb3 stick with, and which booted to the "Where do you want to put Windows?" screen. There was no nvme partition showing.
Then the good news.
I found a .7s folder, downloaded from somewhere(Lenovo?) a month ago, marked NVME_SOP_20170419. After unpacking it, I followed the instructions for both the NVME-pkg-install.CMD and the USB-install.cmd and it produced a working USB stick which booted and, seeing the nvme partition, installed Win7x86 to the 670P. It had no nvme drivers, just the kb hotfixes. Apparently that was all that was needed to get Win7 to the nvme.
Thanks to all of the help given by SIW2, ALEJANDRO85, F22SIMPILOT, WKELLER AND OTHERS. I'm set for the next ten years with 32-bit Windows 7.

Possibly Integrate7 does include them and then overwrites them at a later point in the build.
Possibly I am using Integrate7 improperly (always a possibility!!).
If you look at the nvme-pkg-install.cmd listing, all it shows is the two KB's being added-in by DISM; there is no mention of driver files as there is with the USB3-install.cmd listing.
Actually, I cannot understand the coding. It appears to add the KB's to the boot 3 times(??).

There have been over 9000 views of this thread and nobody has said anything about putting Win7x86 on a desktop M/B.

I totally did, and made mention of those two updates... for Windows 32 bit to boot!
