Class Code:类代码。共三字节,分别是 类代码、子类代码、编程接口。类代码不仅用于区分设备类型,还是编程接口的规范,这就是为什么会有通用驱动程序。 IRQ Line:IRQ编号。PC机以前是靠两片8259芯片来管理16个硬件中断。现在为了支持对称多处理器,有了APIC(高级可编程中断控制器),它支持管理24个中断。
PCI_VERIFIER_DETECTED_VIOLATION 错误检查的值为 0x000000F6。 这表示 BIOS 或 PCI 驱动程序正在验证的其他设备中发生错误。 重要 这篇文章适合程序员阅读。 如果你是在使用计算机时收到蓝屏错误代码的客户,请参阅蓝屏错误疑难解答。 PCI_VERIFIER_DETECTED_VIOLATION 参数 ...
