I have no idea why they make that statment.
A 2P K8T890 should look simular:
| |
|HT[2] |HT[2]
| |
|--+--| cHT[0] |--+--|
| BSP +---------+ AP |
|--+--| |--+--|
| |
|HT[1] | HT[1]
| |
/-+--\
|VIA |
|PCIe|
|Tunnel|
\---+--/
|
| VIA V-Link
|
/---------------\
|VIA southbridge|
\---------------/
Neither of the VIA I/O controllers should have any idea how many CPU's
are in the system.
