Re: Yosemite/440EP 'issues' as a PCI target

Hi David,

However, given the meager host-to-host communications
features, I think I would be better off putting an
Intel 21555 non-transparent bridge on the board.
That will provide 5V tolerance, and a full set of
messaging unit and I2O facilities. All for $50-80
or so according to the single-piece pricing from
Digikey. I'm not so happy to need to add another
chip, but if the 440EP passes all the other
benchmark requirements, then it seems the least
painful way to proceed.

Has anyone reading this list had good or bad experiences
with the Intel 21555 or perhaps some of the PLX offers,
eg. PCI 6254?

We've used the 21555 on a couple of our designs (mated to a 7457/107 
pair) and have never had too many problems with them.  The messaging 
unit has been very helpful.

Just my $0.02,

Andrew
