如何在WIN2000下打开磐英7KXA的AGP支持
如何在WIN2000下打开磐英K7主板7KXA的AGP支持？朋友们不用担心，我们的方法并不困难，相反非常简单。
WIN2000所认识的所有系统设备，都会在一个machine.inf文件中列出，这个文件在您的WIN2000目录的INF子目录中（例如您的WIN2000目录名是windows，则machine.inf所在目录是\windows\inf），注意这个目录是隐藏的，您需要在资源管理器中修改“查看”属性。machine.inf是一个纯文本文件，您可以用记事本打开它，然后发现"VIA_SYS"栏目中的内容：
[VIA_SYS]
%PCI\VEN_1106&DEV_0501.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_0501
%PCI\VEN_1106&DEV_0505.DeviceDesc% = ISAPNP_DRV, PCI\VEN_1106&DEV_0505
%PCI\VEN_1106&DEV_0576.DeviceDesc% = ISAPNP_DRV, PCI\VEN_1106&DEV_0576
%PCI\VEN_1107&DEV_0576.DeviceDesc% = ISAPNP_DRV, PCI\VEN_1107&DEV_0576
%PCI\VEN_1106&DEV_0586.DeviceDesc% = ISAPNP_DRV, PCI\VEN_1106&DEV_0586
%PCI\VEN_1106&DEV_0596.DeviceDesc% = ISAPNP_DRV, PCI\VEN_1106&DEV_0596
%PCI\VEN_1106&DEV_0597.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_0597
%PCI\VEN_1106&DEV_0598.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_0598
%PCI\VEN_1106&DEV_0691.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_0691
%PCI\VEN_1106&DEV_0686.DeviceDesc% = ISAPNP_DRV, PCI\VEN_1106&DEV_0686
%PCI\VEN_1106&DEV_3040.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_3040
%PCI\VEN_1106&DEV_3050.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_3050
%PCI\VEN_1106&DEV_3051.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_3051
%PCI\VEN_1106&DEV_3057.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_3057
%PCI\VEN_1106&DEV_8598.DeviceDesc% = VIAAGP_Install,PCI\VEN_1106&DEV_8598
%PCI\VEN_1106&DEV_8501.DeviceDesc% = VIAAGP_Install,PCI\VEN_1106&DEV_8501
%PCI\VEN_1106&DEV_8601.DeviceDesc% = VIAAGP_Install,PCI\VEN_1106&DEV_8601
在这里，您可以发现VIA芯片组的所有设备编号，并且能从中找到0691和8598这两行。请把下面的两行原样复制到"VIA_SYS"栏目的列表中：
%PCI\VEN_1106&DEV_0391.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_0391
%PCI\VEN_1106&DEV_8391.DeviceDesc% = VIAAGP_Install,PCI\VEN_1106&DEV_8391
继续在文件中查找"VIA_MFG"栏目，栏目的内容如下：
VIA_MFG = "VIA"
PCI\VEN_1106&DEV_0501.DeviceDesc = "VIA Tech CPU to PCI bridge"
PCI\VEN_1106&DEV_0505.DeviceDesc = "VIA Tech 82C5x5 CPU to PCI & PCI to ISA
bridge"
PCI\VEN_1106&DEV_0576.DeviceDesc = "VIA Tech 82C576 CPU to PCI & PCI to ISA
bridge"
PCI\VEN_1106&DEV_0586.DeviceDesc = "VIA Tech 82C586B (PIPC) PCI to ISA
bridge"
PCI\VEN_1106&DEV_0596.DeviceDesc = "VIA Tech PCI to ISA bridge"
PCI\VEN_1106&DEV_0597.DeviceDesc = "VIA Tech V82C597 CPU to PCI bridge"
PCI\VEN_1106&DEV_0598.DeviceDesc = "VIA Tech V82C598 CPU to PCI bridge"
PCI\VEN_1106&DEV_0691.DeviceDesc = "VIA Tech CPU to PCI bridge"
PCI\VEN_1106&DEV_0686.DeviceDesc = "VIA Tech PCI to ISA bridge"
PCI\VEN_1106&DEV_3040.DeviceDesc = "VIA Tech 82C586B Power Management
Controller"
PCI\VEN_1106&DEV_3050.DeviceDesc = "VIA Tech Power Management Controller"
PCI\VEN_1106&DEV_3051.DeviceDesc = "VIA Tech Power Management Controller"
PCI\VEN_1106&DEV_3057.DeviceDesc = "VIA Tech Power Management controller"
PCI\VEN_1107&DEV_0576.DeviceDesc = "VIA Tech 82C576 CPU to PCI & PCI to ISA
bridge"
PCI\VEN_1106&DEV_8598.DeviceDesc = "VIA Tech CPU to AGP Controller"
PCI\VEN_1106&DEV_8501.DeviceDesc = "VIA Tech CPU to AGP Controller"
PCI\VEN_1106&DEV_8601.DeviceDesc = "VIA Tech CPU to AGP Controller"
与前一步骤的方法相似，请把下面的两行原样复制到"VIA_MFG"栏目的列表中：
PCI\VEN_1106&DEV_0391.DeviceDesc = "VIA Tech CPU to PCI bridge"
PCI\VEN_1106&DEV_8391.DeviceDesc = "VIA Tech CPU to AGP Controller"
修改到此结束，别忘了保存machine.inf文件。现在您只需要卸载'PCI standard host CPU bridge' 就一切OK。电脑将从此认识磐英K7主板EP-7KXA的CPU-to-AGP控制器，并且软件也可以使用KX133芯片组的AGP4X性能优势。（Puma 4-21）
