Nettet30. mai 2005 · You might want to read the last paragraph first. Interrupt 1Ch, the User Timer Tick, would probably be a better choice that Interrupt 8 because the code for the interrupt handler can be simpler. To receive Interrupt 1Ch your program must provide an interrupt handler and “hook” the Interrupt 1Ch “vector”, redirecting it to the new handler. Nettet而在BIOS 的8H中断中，有一条指令“Int 1ch”，所以每秒约调用18.2次1CH号中断处理程序。 8254可编程时钟包含三个独立的16位时钟，时钟0用来系统定时的，在BIOS post阶段会初始化为上述状态。 三个时钟分配有三个读写寄存器，分别为0x40、0x41、0x42，还包括一个公用的控制寄存器0x43。 我实际的代码都在Int 1cH中，采用这种方式编程简单， …
