Solution(By Examveda Team)

When installing PCI NICs (Network Interface Cards), you can check the IRQ (Interrupt Request) availability by looking at the jumper settings.
IRQs are essential resources that devices use to communicate with the CPU. Each device requires a unique IRQ to function properly without conflicts.
Jumper settings on the NIC allow you to configure the IRQ assigned to the card. By adjusting these jumpers, you can ensure that the NIC doesn't conflict with other devices already using IRQs in the system.
Dip switches and CONFIG.SYS are not typically used for configuring IRQs for PCI NICs.
The motherboard BIOS can provide information about IRQ assignments but usually doesn't allow direct configuration of individual device IRQs.
Therefore, the correct option is jumper settings.
