This Dutch website documents my exact problem, with photos.

I happen to have a dc7900 SFF PC running W10, and had no issues whatsoever updating the BIOS to the latest version (v01.27) on the support page.
Here is what I did...
Disconnect anything connnected to the PC except the KB mouse and monitor.
Got a USB flash drive and formatted it with the FAT 32 file system.
It is important that you do that first and that you format it in FAT 32 not NTFS.
Downloaded and ran sp73584.
The information page opens.
I use the F10 BIOS setup flashing method.
Click on the View Contents of DOS flash folder.
Copied the file contents of that folder to the FAT 32- formatted flash drive.
Restarted the PC, Tapped the F10 key to get access to the BIOS.
Selected the File tab>Flash System ROM command.
Selected the USB flash drive, and the PC then 'saw' the BIOS update files on the flash drive.
Followed the on screen instructions to update the BIOS, which took maybe 30 seconds or so.
Restarted the PC and was at v01.27.
If that is exactly what you did, and it didn't work, unfortunately, I have no idea why it didn't.

I don't recall what version it had in the beginning.
I think it was the original BIOS (v1.08).
I use the above method for flashing all of my HP business desktop PC's.
I have never encountered an issue doing it that way.
You tried a different flash drive?
You tried a CD instead of a flash drive?
You disconnected all peripherals attached to the PC, except the Keyboard, Mouse and Monitor?
You're lucky the windows based flash didn't wreck your PC since it was running W10.
The windows based flash was only supported up to W7.

The only thing I can think of that I did differently, was that I did not update the Intel Management Engine Firmware.
There are several posts on this forum, and the now defunct business PC support forum where folks have wrecked their PC's when trying to update the IME firmware, so I left that alone.
I also have only updated the BIOS using a PS/2 KB and mouse, ot USB ones.
Is there a specific reason why you need to update the BIOS, or do you just want to have the latest version installed?

I have never put a PCIe x1 ethernet adapter in any of my PC's, but I have not heard of one person that ever got one to work on any HP business desktop PC, not just the dc7900--but all dc7xxx and 8x00 Elite models, so it isn't a BIOS update thing.
You can search the forum for this issue, and probably find many posts regarding add on ethernet adapters not working in the dc7xxx and 8x00 Elite models.
For example this one...And no solutions...
