Does my computer have a pci-e slot

A booted Pi, with a PCIe switch! That's especially true if you're buying used hardware. Running dmesg on the pi to get some driver details, I saw that whilst the PCIe link was active, and some busses were being assigned to the switch — it said that devices behind the bridge would not be usable due to bus IDs.
After seeing his post, and realizing I was meaning to go buy a Raspberry Pi 4, it just seemed natural to try and replicate his results in the hope of taking it a bit further. I am known for Raspberry Pi Butchery , after all.
The USB ports on the Pi board will not function after this modification, so this is super important. I used a hot air soldering station at low volume and medium-high temperature, with small nozzle head in order to not disturb the components nearby. I used flux along the edges and after a while the chip came away. Just cover it with capton or poor electrical tape. The VL datasheet is confidential which makes posting parts of it here tricky. I used 0.
Tinning the end of the wire by scraping with a knife and dipping in a molten solder ball makes soldering to the pads we need easier. Holding the wires down with kapton tape, and using flux, with the smallest iron tip I had made the job just bearable under a microscope.
The first attempt to boot with this setup resulted in the Pi not managing to boot at all. After some wiggling of the PCIe slot, the raspberry Pi booted, but no devices were shown when running lspci lspci can be installed via apt-get. The third attempt, however, after some professional wiggling of the PCIe slot, resulted in success! A booted Pi, with a PCIe switch! However, no devices were detected beyond the ASMe switch. Running dmesg on the pi to get some driver details, I saw that whilst the PCIe link was active, and some busses were being assigned to the switch — it said that devices behind the bridge would not be usable due to bus IDs.
To add a video card to your computer, you have to pick an expansion slot. There have been many kinds of expansion slots over the years so most motherboards contain more than one kind of slot. They usually have a few of the older slots and a few of the newer ones.
The slots differ greatly in speed so you need to pick the right kind of slot. The motherboard shown above includes most of the slots that you'll run into these days. The best slot to use for video cards is the PCI-Express x16 slot.
The next best is the AGP slot. The next best is a PCI-Express x1 slot but video cards which fit that slot are very hard to find as of late The worst choice for a video card is a PCI slot. If you're building or buying a new computer then be sure to get one with a PCI-Express x16 slot. You shouldn't buy anything else. With that kind of computer you're stuck using a very slow PCI slot when upgrading your video system.
You definitely want to avoid that situation. That way you'll have good choices available if you decide to upgrade your video system.
If you only have a PCI slot then your upgrade choices are extremely limited, underpowered, and overpriced. It is technologically superior to the older slots in every way. They all mean exactly the same thing. There's another completely different and incompatible bus called PCI-X so be sure not to get them confused.
