回顾以前Windows 3.x流行的那些日子,安装一个新的Modem、网卡或其他扩充卡的过程经常是无计划或有些盲目性的。那时,我们会将卡插到一个扩充槽中,然后等着看其IRQ(中断请求)或中断信号请求通道是否能幸运地与PC上其他所有的硬件设备的请求通道协同工作,如果不能的话,重新调整设置好比恶梦一样可怕。 In retrospect of the days when Windows 3.x was prevalent, the process of installing a new Modem, network card, or other expansion card was often unplanned or somewhat blind. At that point, we’ll plug the card into an expansion slot and wait to see if its IRQ (interrupt request) or interrupt request channel is fortunate enough to work with the request channel of all the other hardware devices on the PC, if not , Readjusting is just as scary as nightmares.
