Greencreek snoop-filter

[Kilian CAVALOTTI]

Hi all,

I have a bunch of PE1950 using the Greencreek Intel chipset, which features 
a snoop-filter, and I have a couple questions about it:

1. is there a way to know if it's enabled or not from the OS?
2. is there a way to enable it without going to the BIOS? I think 
that "omconfig chassis biossetup" does not allow this action. Is there a 
plan to add this feature?
3; what would be the performance impact of enabling the snoop-filter on 
memory-intensive jobs?

Thanks,
