This means I have to chain to the old interrupt routine, but not every time because I reprogram the timer to tick 50 ticks/sec and the normal rate is 18.2 ticks/sec. How do I do this? _go32_dpmi_chain_protected_mode_interrupt_vector() makes the routine chain every time, isn't it like that? And that is not what I want. So I would be grateful if someone could assist me with this... Thank you -- *************************************** Internet : Henrik DOT Baarnhielm AT abc DOT se Fidonet : Henrik Baarnhielm, 2:201/235 ***************************************
