Jasne, sorry -))))))

 - Intel defined 0 through 20h for use for internal CPU;  IBM
   redefined interrupts 0 through 1Fh for its own use, hence
   the duplicate definitions in the tables
 - all interrupts except the internal CPU exceptions push the
   flags and the CS:IP of the next instruction onto the stack.
   CPU exception interrupts are similar but push the CS:IP of the
   causal instruction. 8086/88 divide exceptions are different,
   they return to the instruction following the division
 - interrupts are disabled upon entry into any interrupt routine and
   should be enabled by the user or by an IRET
 - in DOS 3.2+ hardware IRQ interrupts are re-vectored through DOS
   to provide standard stack frames
