For example, when the modem needs to run a process, it sends an interrupt request to the CPU saying, "Hey, hold up, let me do my thing!" The CPU then interrupts

Next to each of the other device types will usually be a ‘+', which means there are devices defined under this type. Irq Statistics Interrupt 13 is used for math coprocessor. This specifies which interrupt line the device may use. this content With the PCI expansion bus different devices in the system can actually share the same interrupt.

The following table is an overview of the traditional IBM IRQ's, I/O ports, and their related devices. Irq Sticker Beware, however, that using this method may hamper the automatic configuration of any new PnP devices you install. They will typically have a list of all 16 IRQs, with the default setting as ‘No/ICU', which means that it is *not* reserved, and can be assigned by the Interrupt Controller If we assign wire 2 to some device, the system will substitute it with wire 9 which is on the second PIC.

Pooling gives each device a certain amount of time to interact with the CPU.

If you add a device that does not support Pnp, the manufacturer will hopefully provide explicit directions on how to assign IRQ values for it. Interrupt 5 is assigned to the second parallel port, LPT2 (this interrupt is often free so it is used for a sound card). If you see a ‘!' (exclamation point) next to any IRQ number, this means that either the IRQ is in use by another device, or the Win95 driver which assigns this Hardware interrupts are used to handle events such as receiving data from a modem or network card, key presses, or mouse movements.

It is possible that a few more might be squeezed out of the architecture, but not very likely. The intention was to have the hardware and the operating system ‘negotiate' for an available IRQ. By doing this we theoretically get 16 IRQs. Assigning IRQs As it turns out, Plug'N Play is one of the most frustrating issues we have encountered in hardware configuration.
