Hi all,
This is my first message here.

I'd like to know if anyone has had an experience in using an Intel 31154 bridge.

We are using this bridge to "bridge" a 64bit PCI-X bus to a 32bit PCI bus.

I'm a little bit concerned about the documentation, where I cannot well understood
how to properly set the the buses' width for both sides.
I mean, it seems that some pull-ups must be added to the higher 32bits while not used &| not driven, but is this the only way to "inform" the component?

Thanks in advance to everyone who has sorta answer.

Regards,
MG
