In theory this can be applied to any slot that provides more than 1 PCIe lane off of the PCH in an Intel machine, as long as you can find the appropriate version of the Flash Image Tool and have a bifurcation board the physically fits where you want it.

Oddly enough I wasn't able to get it working fully on a ThinkCentre M720q though, more research to be done for that one.

It works!
The first customers are getting their 4 Layer 0.8mm boards. 🥳 This board is a Latitude 5491 SSD Expander designed by @WifiCable_ Interested in our affordable 0.8mm 4L PCBs? Take a look at our design rules: community.aisler.net/t/4-lay…

Just testing the clock buffer for now, haven't gotten a machine to bifurcate its slot just yet. More testing to doooo, but the board itself is all good.

So as you could probably already tell, I've got my hands on some E4310's with Latitude ON, the funny 2nd little PC inside the laptop with an ARM CPU. After a day of messing around I've already got some interesting things to tell about it.

Oh right of course, there's FCC pics of that one as well. fccid.io/E2K-DWBT2/Internal-…

The FCC is quite lovely for posting internal pics of so many devices (and it seems they also have the schematics for everything but those aren't publicly available. If only someone around there would be so kind to accidentally misconfigure something and expose them to the public)

E4310: is a wireless device *looks inside*: wifi cables

It was quite difficult to get the 3rd main wifi antenna routed back to the UWB slot, but it just barely reaches and seems to work quite nicely. All 3 miniPCIe slots in this machine have PCIe and USB wired up to them and no whitelist shenanigans, so I can put in whatever I want!

Technically there's 4 wifi radios in here now if you count the Latitude ON one, though that one can't work at the same time as the rest.

On the E4300, it gets converted straight from the OMAP's RGB output to LVDS, while on the E4310 it gets converted straight to eDP. I really have no idea why they jammed VGA in the middle there on the Z600.

I think that's about it for Latitude ON specifics. Thanks for reading! If you got any questions feel free to ask.
