Hi, I've got a HP T620 Plus hanging around that I'd like to experiment with Win98SE. Obviously the integrated graphics doesn't have drivers, but there are some PCI-E versions of GeForce 6200 that might fit inside it without the shield (the thin client has a PCIe 2.0 x4 slot). Would it work? The unit has just msata/m2 connectors inside (plus two hidden usb connectors). What sort of external USB soundcard should work with win98se?
