, which uses the AMD-8131 hypertransport pci-x tunnel+amd-8111 I/O hub chipset, with the largest support for 2 AMD Opteron processor (UPGA 940-pin). Because the Opteron processor consolidates the memory controller, the memory DIMMs on the motherboard are divided into two groups, each of which is controlled by a single processor memory controller. 4. Two Opteron 246 processors (2GHZ,1MB L2 cache) are configured on the test server, which consolidates th

affects the frequency of PCI and other bus. The two concepts of the front-end bus and the outer frequency are confusing, mainly because of the long time before (mainly in the Pentium4) the front-end bus frequency is the same as the outer frequency, so it is often called the front-end bus as the outer frequency, which leads to such misunderstanding. With the development of computer technology, it is found that the frequency of the front-end bus is hig

disable the lnka device, The ACPI Specification defines that the OS must execute the _ dis function of the device. From the hardware point of view, to disable the lnka device, you need to set the maximum position of the configuration space register of a PCI device to 0 × 60. The OS does not need to know the hardware details. It just needs to explain and execute the _ dis function. The above code is the AML code, provided by the bios, with the 'or (\

Questions raisedThe general motherboard has two NIC interface, Linux system is generally named after boot eth0,eth1, of course, if we do not eth0 and eth1 post-processing, each boot eth0 and eth1 location will not be fixed. Therefore, when the external network card, the problem of port confusion (port name and port of the
