Though I almost ( 15 min ago)got it running under my WinXP virtual PC version since I have Win 7 PRO, except the "simulated" Graphics card there does not have 3D acc.
Yes, Virtual PC emulates the S3 Trio video card with 8MB video memory and no hardware acceleration.
Virtual PC is good for Windows games from the 1990's or those few later games that don't require 3D acceleration.
Functionally XP Mode is the same as Virtual PC with XP installed, only it's made so it looks more integrated into the Windows 7 desktop than Virtual PC normally is.
If you're interested and you have the Windows CD, you could try VMware Player (free for home use) and enable 3D acceleration as described at
https://www.vmware.com/support/ws5/doc/ws_vidsound_d3d_enabling_vm.htmlVMware renamed VMware Player to "VMware Workstation Player" but it's the same thing.
***link to VMware Workstation Player download***Inland used to use VMware Player for some games instead of Virtual PC. I don't know if he ran Syberia this way though.
If you are using XP or later, there is also VirtualBox, and there are instructions for enabling 3d acceleration here
https://www.maketecheasier.com/enable-3d-acceleration-in-virtualbox/Usually when I run a Virtual Machine it is with Windows 95 or 98, but this has gotten tricky for more recent computers due to their increased speed (both processor speed and hardware virtualization capability).
Of course if all you want to do is play Syberia, it's easier to buy a pre-patched download without the DRM. But not all old games have download versions, and for those you might want to try a VM and see how well the 3D graphics emulation works.
