Interrupt Vector Table (organized by xjmxjm1234)

Not bad, I support! Especially your spirit!

But the book <PC Interrupt Encyclopedia> provided by QB45 seems to be more detailed, but many are no longer applicable now.

Good stuff

Brother Guxing, how to use this "interrupt vector table"? Can you explain it?
