What happens if you try to read from a null pointer in DOS?

I haven't actually tried this, but based on my understanding of the MS-DOS memory model it should read the contents of memory at address 0.

This is correct, and address 0 is the start address of the interrupt vector table, so there are good reasons why you might read from it.

You get what is at 0x0000 ?
