Contrary to popular belief, the driver for the OS running on the virtual machine (Microsoft Hyper-V Video") is added to the Microsoft operating systems as any other driver, presumably when virtual machines were first added. The driver, "Microsoft Hyper-V Vide") is released (and therefore, incorporated) into systems that released after it -- Windows 7 had it, Windows 8, 8.1 and 10 got them all. The ones before, such as the (beta) of Longhorn or the more familiar XP or Win 2K don't, so there will forever be this "question-mark" video adapter.
I would assume that the best move here is to not install a adapter, although ATI Rage 128 Pro was the one I used physically on my win2K build.
Eh ... hmm my virtual Win 2K crashed (BSOD) when I am browsing screen savers. interesting ...
I NEED THE DISPLAY ADAPTER DRIVERS!!!!!!!
And hey, this "adapter" clearly doesn't support hardware-based acceleration. Seen in V2K by the displaying of corrupt images (desktop icons!) and some corruption after cursor movement.
That being said, I am still wondering what are the other two "unknown devices". Infrared? Bluetooth? Windows linked by USB? I don't see those in Virtual Machine settings ...
Or at least tell me how to extract those from a Windows installation disk.
