I'm trying to figure out whether my system supports PCI Express without opening up the box. lspci doesn't mention "Express" or "PCI-e" anywhere, but dmesg reports that a "PCI Express Hot Plug Controller Driver" is in use.

Easiest thing you can do is restart the machine and write down the model number then Google it and look up the specification.
Simple, but works!

That's a good point, the BIOS POST screen will usually display a model number of some kind which as you say can be fed into Google. Nice idea. – Mokubai – 2010-02-19T14:36:59.273

If you want the motherboard make and model so you can google it, but you don't want to reboot, you should be able to get that info from /sys/class/dmi/id/board_vendor and /sys/class/dmi/id/board_name

One thing to note is if your machine has a 1x, 2x, 4x, 8x, 16x PCI-E port and then buy the appropriate hardware.

2Why are you avoiding opening the PC? Due to a warranty sticker? Could you lookup your PC from the manufacturer/supplier to see what is on the product specification? – user155695 – 2010-02-19T14:23:52.027
This would be a fun solution to see +1. I wouldn't mind having this ability for when I am not in front of a machine. – Urda – 2010-02-19T14:26:41.787
