Matthew, Yes, I can see extended regs on the same system using WinXP and CatScan (http://www.getcatalyst.com/product-desktop_catscan.html) >BTW, I assume you have CONFIG_PCI_MMCONFIG=y in your .config? I am not sure exactly what this means. I think you are asking if I built the Linux Kernel from source. I did not build the Linux kernel from source. I installed Linux on this PC (and many others) using FedoraCore CDs and basically selecting defaults for everything. I assume that the defaults would be correct. Bad assumption?
