Can anyone help me to find the register which containts <B>PCEXBAR</B> - PCI Express Base Address? I looked through the <I>Intel Xeon Processor E5-1600/2400/2600/4600 (E5-Product Family) datasheet volume 2</I>, but have not find the register. For exmple, for Core i7 2nd/3rd gen processors, the <B>PCEXBAR</B> is located at Bus 0, Device 0, Function 0, Offset 60-67h [bits 38:28]. Please help, my customers worry about the lack of my software.</P><P></P><P>Thanks!</P> Thu, 26 Jul 2012 11:43:59 GMT VJung 2012-07-26T11:43:59Z https://community.intel.com/t5/Embedded-Intel-Core-Processors/PCIE-Extended-Configuration-Register-Space-Access/m-p/255570#M2609 <P>Hello!</P><P></P><P>I'm trying to access PCIE Extended Configuration Registers (100h - 1FFh) from my software on my Xeon E5-2600 series based platform.
