I got 740 as well, now trying to solder SATA, Ethernet and fan and power connectors.
it does require some soldering (both the port and 4 capacitors)
Which caps are these and what size? Also, seems like a lot of components are missing, caps, resistors, inductors, some ICs...what about them? Do you have any schematics by chance? I couldn't find anything. As for the SATA connectors, did you use something like Molex 67800-8005?
And the same questions for the Ethernet port – seems like there are
ton of components missing. Is it possible to do it without any schematics? Or purely by Intel i210 datasheet/similar i210 schematics online? And the BIOS question: if after soldering it's not recognized, is it be possible to flash D3544-S bios on 740?
Also, have you tested an NVMe drive together with SATA? In the Futuro D3544-S
datasheet there is a note:
M.2 (SATA mode only) is shared with SATA port 1
If I understand correctly, then if m.2 port is used as SATA, then only 1 out of 2 soldered SATA can be used. But if NVMe is used, then I suppose both SATA ports can be used?
The other m.2 slot for the wifi is a+e and i've tried running an ethernet a+e from that port and even though it does power on it does not seem to be detected when the OS is booted.
You've tried something like i210 on m.2 a+e key?

datasheet specifically lists Intel 9260, I guess it's locked on it. If it's indeed an enforced whitelist, then you can probably
try patching bios, if you have an SPI programmer, but I'm not sure if it's cryptographically signed. But from the article, seems like (in case of Lenovo) they actually stop the boot process and print "Unauthorized Wireless network card is plugged in", so it will be harder to find it in Fujitsu. I'll try to do it on the weekend, should search for something like 'wwan/wlan lock':
I had a very similar issue with HP Elitedesk – the NIC just doesn't show up, even though it's powered on, and no warnings during boot.
