现有一台486/33兼容机,其配置为4MB内存,200MB硬盘,128KB片外高速缓冲器和8KB片内高速缓冲器。故障现象该机运行极不稳定,常常是在装入文件或程序执行中死锁,同一操作命令(如读目录文件)时有死锁;尤其是在运行WPS模拟显示和PCTOOLS的读文件目录操作时均造成死锁。故障分析系统工作很不稳定,初步判断问题可能出现在系统板上,极大可能是系统板上的部分组件之间的不匹配。一般说来CPU与存储器间的不匹配是一个重要因素,如内存的工作速度与CPU的工作速度不相适应。如果486所选的内存的工作速度低于70ns,机器容易死机。
There is a 486/33 compatible machine configured with 4MB RAM, 200MB hard disk, 128KB on-chip cache and 8KB on-chip cache. Fault phenomenon The machine is running extremely unstable, often deadlock in the load file or program execution, the same operation command (such as reading the directory file) deadlock; especially in running WPS simulation display and PCTOOLS read file directory operations Deadlock caused when all. Failure Analysis System work is very unstable, initially determine the problem may appear on the system board, most likely some of the components on the system board does not match. In general, the mismatch between CPU and memory is an important factor, such as memory speed and CPU speed does not match. If 486 selected memory speed is less than 70ns, the machine crashes easily.
