I have got motherboard p8H77-i with H77 chipset. lspci for that board says:
00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor DRAM Controller (rev 09)
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor PCI Express Root Port (rev 09)

03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168 PCI Express Gigabit Ethernet controller (rev 09)
The question is about lspci output and what the datasheet(7-series-chipset-pch-datasheet(http://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&sqi=2&ved=0CDAQFjAA&url=http%3A%2F%2Fwww.intel.com%2Fcontent%2Fwww%2Fus%2Fen%2Fchipsets%2F7-series-chipset-pch-datasheet.html&ei=fkafUaiIBsyAhQfAt4HADg&usg=AFQjCNHgY_3FYq9TMot9JvcjzD-8M4iWog&sig2=nxDN6J0G8sYm9U5xe8S2Bg&bvm=bv.47008514,d.ZG4) says.
For example
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor PCI Express Root Port (rev 09). Is not in the datasheet. There are only 2 PCI express root ports:
00:1c.0 PCI bridge: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 1 (rev c4)
00:1c.4 PCI bridge: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 5 (rev c4)
There is also no description of
00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor DRAM Controller (rev 09). According to the information from Intel, that PCH doesn't have memory controller.
Is it me being stupid or I'm looking at the wrong datasheet?
