Re: How to $B!H(Bfake an interrupt$B!I!)!)!)(B

Of course, the code that you’ve invoked when you do this will send an EOI to
the interrupt controller where there was no hardware interrupt. This will
inevitably dismiss some *other* interrupt, causing another ISR to be
skipped, causing indeterminate system behavior. (And this is just the most
obvious of problems here.)

You can try this.
You need to know(determine) the interrupt vector.
Suppose it is 0x53,
Now you can fake an interrupt using
__asm int 0x53

Note: you can’t use variable names with “int” instruction. you might prefer
to use a switch statement.
