>Manually setting dip switches and setting pins to try to get your cards to each have a unique IRQ
Also, thinking about which IRQs are available when buying a hardware device and how that maps with possibilities for existing devices.
Even more fun - realizing that the solution is to swap network cards amongst a couple of computers because the other network card has more options. So you do the swap (and update the software to use the new ports) and then hope that both computers will even load afterward.
Had to do the planning by hand since this was before I was on the Internet and I don't remember seeing web apps that help with this.
