驱动编程 This sample provides a generic example of a PCI IDE minidriver. The sample isolates vendor-specific

This sample provides a generic example of a PCI IDE minidriver. The sample isolates vendor-specific code from the higher-level PCI IDE bus driver, much as SCSI minidrivers isolate code from the SCSI port driver. See the Release Notes section for more information. This sample works on both x86 and A ...
