摘　　要：依据PCI规格,理解PCIBUSCOMMAND中的I/OWRITE这一动作的状态,以传统的PCIDebugCard(Port80H)作为背景,阐述了如何开发一种多功能的基于PCIBUS的除错卡,在方法上采用了现代工程研制模式,为诊断主板故障从理论上提供了一种有效的方法。Considering the format of PCI and the acting state of I/O WRITE in the PIC BUS command, how to develop a multifunctional debug card, on the traditional PCI debug card (Port 80H) by using PIC BUS as a basis is discussed. The modern engineering developing mode is adopted. Theoretically, an effective novel approach for diagnosing the faults from the main board is provided.
