I have read the appropriate FAQ etc but am still unsure.
The example key board isr is not all that clear because I'm not intimately 
familiar with assembly language (definitely not with that style of
assembly language).

Do I need the go32 wrappers when writing a real mode isr?

If not do I need to add the entry and exit code for the isr as well as
my specific code?

How do you place code in a memory block(allocated with
__dpmi_allocate_dos_memory(...))  with dosmemput(...).

Do you do so by writing the function and then setting up a pointer to it
and passing the pointer to dosmemput(...)?

If so how do you know how much memory to allocate with
__dpmi_allocate_dos_memory(...)? sizeof ISRFunction(...)?
