Well, afaik the way the support is implemented is by replacing at least par= t of the windows / linux gfx stack (details depend on the product). So, win98 ha= s different versions of gfx APIs that need replacement and since there is "no market" nobody cares to write this code. OTOH, qemu is open-source software so nobody is going to stop you from scratching your itch if you are skilled and want / need win98 accelerated graphics. > 6.Last Question will there be any speed advantage from porting Qemu to=A0= run > on a GPGPU or a X86 GPU such as Intel Larrabee. Probably this is a moot point since there is no (obvious) way to pull off such a trick as porting a complex piece of system software like qemu to a stream compute= r. OTOH, the emulation of some of qemu's "virtual peripherals" might be possible to speed up, or the underlying OS could be speeded up in ways that might benefit qemu. But before any of this happens, gpgpu would need to become more "mainstream= " and expose a standard cross-vendor API. Cheers, Pantelis
