Yes, sorry. Correct declaration is
void interrupt int60(void).
Im pu****ng things into the stack because since the isr is in c++, it
automatically puts pushes and pops at the beggining/end of my isr. I
could write the whole thing in assembler, but I=B4ll be dealing with
file manipulation in other parts of my tsr, and i dont have too much
knowledge of that in assembler.

You can see a mov bx, 00aa cause i added that line in my c++ for
debugging. I was just testing it, so it was ok bx=3Daa.
Funny thing... Looking at the rest of the code, I see the disassembler
specifies The beggining of my isr a few bytes before the initial pushes
of the isr....

and ends a few bytes after iret. I dont know if it is a disassembler
bug, or would c++ be setting wrong vector address. That would cause a
big crash for sure. Anyway, the isr seems correct to me, assuming the
first push as the start. How could i be sure my isr is loaded correctly?
