I want to chain to a protected mode ISR from my own ISR which is written in C, but I don't want to use _go32_dpmi_chain_protected_mode_interrupt_vector() (I want to run the default ISR every other time my ISR runs.) Is it possible to do this from C or do I need to do it from assembly? I know that I can get the selector and offset of the original ISR using _go32_dpmi_get_protected_mode_interrupt_vector(), but I can't seem to find a go32 or dpmi function that let's me call the routine. Thanks, Tony Richardson
