Using a Matrox MXO2 Dock with Windows 7 32 bit Thunderbolt 3 laptop

I was quite surprised to find this was even possible.

I believe the Matrox MXO2 Thunderbolt 2 Dock came out in 2010 and was directly targeted for the Apple Mac OSX 10.6 market.

But after installing and activating Windows 7 x32 on an HP Folio G1 laptop with a USB3/Thunderbolt 3 port, and using an Apple Thunderbolt 3 to Thunderbolt 2 adapter.

At first the MXO2 Dock powered up green, but the OS could not see it.

So I had to install the HP sp85610.exe package - Intel Thunderbolt 3 Secure Connect Utility

It detected the Matrox MXO2 "knocking" on the PCI buses door, and I changed the answer from Block to Allow.. and suddenly PCI bridges and device drivers started installing.

When it was done the only device it couldn't find a driver for was the Broadcom Extreme Gigabit Ethernet port of the Dock.

I hunted around by PCI VEN and DEV to find the HP Broadcom 17 sp82011.exe package had that driver and installed it.. it was a universal installer so it brought along a lot of peripheral management software and installed a 32 device driver for the Ethernet port.. and it detected the network and setup the adapter.

So now its fully functional.

I tested both the USB 2 high speed ports.

I tested the USB3 super speed port.

I tested the HDMI port and could extend or replicate the Intel 515 display on an external monitor.

I tested the Ethernet port.

 All work as expected.

I'm really curious to see if the Matrox MXO2 capture devices like the mini, mini-max and LE can also be used through the proprietary PCI "host" port on this dock to avoid using the ugly little black host to Thunderbolt 2 boxes, or the PCIexpress card or the PCIe PC card.

It just seems a more future proof way of using the old capture devices on newer hardware.. even if it has to be with Windows 7 - Flashboot provides a way of installing Windows 7 even on newer hardware without a CSM compatibility bios extension with a UEFI shim to support ancient bios legacy calls for the startup screen and bsod windows.

I assume this will work for Windows 7 x64 but its a guess.. a 32 bit install was a little older and closer to what was more common at the dawn of the Vista and Win7 age.
