I gather gfrom what you've written that the TGA does not generate interrupts either, so doesn't need the IRQ. PS: _Every_ PCI device gets assigned an IRQ whether it needs it or not. I'm not sure if the spec actually says this, but in my experience with PCs, it seems to be the way things work. -- Lee Cremeans -- Manassas, VA, USA (WakkyMouse on DALnet and WTnet) A!
