dos系统原先情况:
有个程序A在正常运行,产生数据存放到一文件A中。
设计需求:
现在有块板子,用的是8253做定时中断,他接的是IRQ3,中断能正常产生;现在我做了个中断驻留程序,想用irq3的中断对文件A操作。 我用ctrl+break中断模拟中断中的文件操作,老是死机,希望有能力的朋友共同帮忙解决;

Original situation of the DOS system:
There is a program A running normally, and the generated data is stored in a file A.
Design requirements:
Now there is a board that uses 8253 for timing interrupts, and it is connected to IRQ3, and the interrupt can be generated normally; now I have made an interrupt resident program, and I want to use the interrupt of IRQ3 to operate the file A. I use ctrl+break interrupt to simulate the file operation in the interrupt, and it always crashes. I hope that capable friends can help solve it together;
