What 2 IRQ's could you assign to a NIC without causing a conflict with preassigned devices?

To avoid conflicts with preassigned devices, you could typically assign IRQs 10 and 11 to a Network Interface Card (NIC). These IRQs are often available for use in modern systems, as many standard devices are assigned IRQs 1 through 9 or 12 through 15. However, it's always best to check the specific hardware configuration and the system's IRQ routing table to ensure there are no conflicts.
