计算机的调试工作一直十分麻烦,要为每一个硬件分配输入/输出地址空间、中断、直接存储访问通道等系统资源,而且要保证没有任何硬件冲突。也就是说,在同一系统中不能有两个硬件使用同样的资源,为此得搞清硬件设定与所需资源的复杂关系,然后多次更改双列直插式开关或跳线的设定,才可能在没有任何冲突的情况下,结速这麻烦而无味的调试过程。可有了即插即用以后,就无须为这种棘手的过程费神了,计算机自动做好了大部分设置,使各部件自动相互兼容,基本上没有冲突。 但即插即用毕竟是新生事物,总有不完善之处,而且各厂商也未必会完全遵守即插即用规范,加之人们缺乏必要的 Computer debugging has been very troublesome, for each hardware allocation of input / output address space, interrupts, direct access to storage channels and other system resources, but also to ensure that there is no hardware conflict. That is, no two hardware in the same system can use the same resources, for which reason you have to figure out the complex relationship between the hardware settings and the required resources, and then change the DIP switch or jumper settings multiple times , It is possible in the absence of any conflict, the speed of this boring and tasteless debugging process. With plug-and-play, there is no need to bother with this tricky process, and the computer automatically does most of the setups so that the components are automatically compatible with each other and there is virtually no conflict. But plug and play, after all, is a new thing, there are always imperfections, and the manufacturers may not be fully comply with the plug and play norms, coupled with the lack of necessary
