I guess "firewire" includes the internal hardware >interface also. In a similar vein to the UHCI, OHCI & EHCI standards for USB host controllers there is also an OHCI (Open Host Controller Interface) standard for Firewire host controllers. As far as I know all vendors now follow this. Aside from minor quirks this should make things pretty straightforward. (OHCI USB & OHCI Firewire standards are very different, don't be misled by the similar names.) Be aware that old Firewire controller chips may have a vendor proprietary interface. This should only affect adapter cards. Firewire on the motherboard is recent enough that all systems should be OHCI compatible. Tony
