as for point 2.

Processor Exceptions and Their Definitions
00: Divide Fault
The processor returns this exception when it encounters a divide fault. A divide fault occurs if division by zero is attempted or if the result of the operation does not fit in the destination operand.
02: NMI Interrupt
Interrupt 2 is reserved for the hardware Non-Maskable-Interrupt condition. No exceptions trap through interrupt 2.
04: Overflow Trap
The overflow trap occurs after an INTO instruction has executed and the 0F bit is set to 1.
05: Bounds Check Fault
The BOUND instruction compares the array index with an upper and lower bound. If the index is out of range, then the processor traps to interrupt 05
