When I Run OpenGl My Modem Disconnects

When I am connected to the internet through a dial-up modem and I use OpenGl with Half-Life my modem disconnects. Both are using IRQ 09 and I don’t know if that makes a difference.

There’s your problem right there. Your Modem and Video card should not be on the same IRQ they should have an IRQ of their own. MOst ppl’s vid card is on IRQ 11.

how do i change the irq?
