IRQ5

An IRQ5 is an interrupt request line on a computer's motherboard. Interrupts are signals sent by hardware devices to the CPU to indicate that they need attention. IRQ5 is one of several interrupt lines available, each assigned to a specific device. Historically, IRQ5 has been commonly used for sound cards and other expansion devices. In modern computer systems, the use of IRQ lines has largely been replaced by more advanced interrupt handling mechanisms like Message Signaled Interrupts (MSI). However, understanding IRQ lines can still be relevant for troubleshooting older hardware or in certain specialized computing environments. Conflicts can arise if multiple devices attempt to use the same IRQ, leading to device malfunction or system instability. In such cases, manually reconfiguring the IRQ assignment for one of the devices, if possible, can resolve the issue.
