This question is irrelevant on modern PCs, and has been for roughly the past 10 years. Back in the 90s, sound cards were plugged into the ISA bus, which until the very end required manual IRQ configuration. The most common line of cards was SoundBlaster by Creative Labs, which become the de-facto standard. On a typical early SoundBlaster cards or third-party imitations, you could generally choose between IRQs 2,5,7 or 10. IRQ 2 was often reserved for the system DMA controller, and IRQ 10 wasn't always addressable on some motherboards. Many cards had a default of IRQ7, but if you turned on na ECP Parallel Port, it would conflict as well. That left IRQ5, which typically didn't have many conflicting devices with the possible exception of an internal modem that couldn't use IRQs 4 or 3 because both RS232 serial (COM) ports were already in use. There is still a debate from people who were involved at the time whether the "real" default was IRQ5 or IRQ7. It didn't matter that much then, and it doesn't matter at all now. It was simply a question of implementation on the specific model of card that you got. Later on, more advanced 16-bit and wavetable cards like the Soundblaster 16 or AWE32 and Gravis Ultrasound provided a much wider array of IRQ choices, and most could be configured via software, or configured themselves automatically. When the PCI bus replaced ISA, the entire IRQ/Address/Port range manual configuration issue became moot.

What IRQ does a monitor use?
None. Its the graphics card that uses an IRQ. The monitor is just a peripheral.
How do you overcome the IRQ conflict with sound card?
You need to identify which device the sound card is conflicting with and then find out if you can change the IRQ on one of the devices. If you cannot change the IRQ for one of them, such as via a dip switch or jumper, then you will have to remove one of the devices.
Irq 6 is commonly assigned to?
it's assigned to control keyboard
Which IRQ does a floppy disk controller typically use by default?
A floppy disk typically uses IRQ6 (that is on windows server 2003)
List interrupts used with the IBM PC type sytems?
IRQ 0 - System timer. IRQ 1 - Keyboard. IRQ 2 - Cascaded signals from IRQs 8-15. IRQ 3 - COM2 (Default) and COM4 (User) serial ports IRQ 4 - COM1 (Default) and COM3 (User) serial ports IRQ 5 - LPT2 Parallel Port 2 or sound card IRQ 6 - Floppy disk controller IRQ 7 - LPT1 Parallel Port 1 or sound card (8-bit Sound Blaster and compatibles) IRQ 8 - Real time clock IRQ 9 - Free / Open interrupt / Available / SCSI. Any devices configured to use IRQ 2 will actually be using IRQ 9. IRQ 10 - Free IRQ 11 - Free IRQ 12 - PS/2 connector Mouse. IRQ 13 - ISA / Math Co-Processor IRQ 14 - Primary IDE. If no Primary IDE this can be changed IRQ 15 - Secondary IDE These are just a set of standard IRQs. For much more detail check our Ralf Brown's list located at http://www.cs.cmu.edu/~ralf/files.html
Which port names and resources are assigned to most PCs?
COM1 is assigned 3F8h and uses IRQ Channel 4, COM2 is assigned 2F8h and uses IRQ Channel 3, COM3 is assigned 3E8h and uses IRQ Channel 4
What is IRQ 5?
This interrupt is the first choice that most sound cards make when looking for an IRQ setting.
IRQ address typically used for LPT2?
5
How you would reserve irq 5 for a legacy sound blaster 16 audio card in the cmos?
Pls!!! Check or coppy the answer from your friends next you`>>>>>>>` Copy copy
If a sound card operates correctly except when a printing operation is in progress what is most likely the problem?
This problem won't be found in any relatively modern computer. On a much older system, it would indicate that the sound card and LPT1 were sharing the same IRQ.
If IRQ 2 is in use IRQ 9 cant be used?
Depends if it's sharable or not. You could try moving the card to another slot.
Suppose you want to add a legacy sound to your system that uses IRQ 5 what if anything is currently using this resource?
IRQ 5 is normally a free interrupt unless you have a second parallel port installed. If the interrupt is currently in use by another resource, you could reassign the IRQ that one of the conflicting resources is using to a less commonly used interrupt such as 10, 11, or 12.
