I just bought a PCI card (a very cheap generic one) and I can't find any compatible drivers. I get PCI Serial Port and PCI Parallel Port in other devices in Device​ Manager. I'm using Windows 8.1 x64 and ASRock Z68 Extreme7 Gen 3 motherboard. EDIT: On the card it says PCI 2S1P GP 323B6617G 07/23 EDIT2; I found out that the name of the card is HP DC195A and most people say it doesn't work on any Windows newer than XP. As @Tom Tancredi said, it might work with Windows 10 due to better legacy support. Is that my only option now or is it there a workaround to use XP drivers on 8.1?

A) No idea WHY you would want a serial / parallel ports as they are way obsolete B) Devices whom use those ports are NOT supported anymore, so if you have a old printer, it won't probably be recognized by Windows because it isn't supported C) Windows used GENERIC drivers, so the PCI card IS SEEN in the Device Manager. If you want specific ones, you would need to use the included disc OR go to the Manufacturer's website, but again, probably WON'T be compatible with Windows. Yamaha electronic keyboard manual. D) Windows 8.1 is no longer supported by Microsoft FYI: you need to update to Windows 10 to utilize current drivers and such. Windows 10 also does alot better LEGACY support as compared to 8 (which was made mainly with the idea everyone was using NEW Tablets not OLD desktops - smh!).
