From: Manfred Knick To: bug-followup@FreeBSD.org, Manfred.Knick@T-Online.de Cc: Subject: Re: kern/128331: [agp] nForce3-250 AGP not detected correctly Date: Mon, 24 Nov 2008 12:24:25 +0100 ADDENDUM: Digging further on, I came across http://www.ocworkbench.com/2005/uli/m1695/g1.htm which states: M1695 ... Tunnel Chip ... is ... chipset that uses a tunneling technique to interconnect the two "North Bridges" as the South Bridge ... . Thus, the approach is as follows: [ CPU ] <-- HyperTransport Link --> [ M1695 ] <-- HyperTransport Link --> [ nForce3 250 ] <-- AGP Bus --> [ G550 ] which implies that indeed we have two host bridges, but sequentially - not in parallel.
