Putting a VGA card behind a PCI-to-PCI bridge is probably not that clever, but it does not seem that 2127X (X=2?) core logics used with 21264's utilize a PCI-to-PCI bridge for PCI BUS #1 (I mean both PCI BUS controllers seem to be attached to the system BUS). Note that I have been unable to find any detailed documentation about core logics used for the 21264, so I may be just wrong on that point. :( > > > Where does it say the 83C895 does not work?

Thanks for the enlightment about meaning of `hose' in this context. :-) > I will write a clarification around this in HARDWARE.TXT Regards, Gérard.
