a) The value passed in
CX should be a valid protected mode code (executable) selector, not a real
mode segment address.
b) Every exception is
first examined by the DPMI host. If the host does not handle the exception,
it reflects the exception to the first handler in the protected mode exception
handler chain.
c) DOS/32 Advanced DPMI
supports only first 16 exceptions. Calls to this function with value in
BL greater than 0Fh, but less than 1Fh, will return without performing
any action.
d) DOS/32 Advanced DPMI
does not handle exception 0Ch (Stack Fault).
e) DOS/32 Advanced DPMI
will install exceptions 08-0Fh in an internal buffer, not in IDT, when
PIC master is mapped on these interrupts (INTs 08-0Fh).
