IRQ reassignment.

[Dinosaur]

Windows 98 SE. ASUS A7V133 Jumper free Motherboard with AMD Athlon CPU (1000MHz).

I have never reassigned interrupts, but believe I know how to do it via Device Manager. I am nervous about creating problems since I am so ignorant in this area.

There seem to be a lot of devices using IRQ 5, including a Creative Labs Sound device. Since the system hangs up a lot after I install the Creative Labs sound drivers, I suspect that IRQ conflict is the problem. Some information from the Creative Labs Web sites makes me believe that IRQ5 is assigned to a creative labs device which can use IRQ7.

Before installing the sound drivers, IRQ5 is assigned to 4 devices. A PCI Data Fax Modem, an IRQ holder for IRQ steering, and two PCI to USB controllers. The latter look like two copies of the same device, but I assume the two entries relate to the two active USB ports.

Does anybody have advice about the following scenario?

I intend to free up some interrupts by reassigning IRQ’s used by COM1, COM2, & LPT1. COM1 & COM2 (IRQ 3 & 4) are not in use. At least nothing is plugged into them, and my Modem is using IRQ5. IRQ7 is used by LPT1. I intend to assign IRQ4 to LPT1 and COM1, leaving IRQ3 & IRQ7 available. I assume this will cause no trouble since COM1 & COM2 are not used.

Then I intend to install the sound card & drivers, after which I will try to unhang the system and assign IRQ7 to the Creative device using IRQ 5.

I have the same board, cpu & OS. I've heard folks having probs with the sound card installation. Instead of fighting the IRQs could you just move the card to another PCI slot? Also, make sure you disable sound by jumper and in the BIOS...I had problems when building until I did both. Just a suggestion...besides I don't feel like deciphering IRQ assignments on my system.

Hey Dinosaur,
I have the same type problems with a Creative Modem and my sound card. System hangs and I get a sound loop http://www.PCGuide.com/ubb/mad.gif Only way to stop it is power down the machine. This is an older 95 box. The problem is fixed with updated drivers from Creative, but every time I reformat, its a different proceedure to get eveything working http://www.PCGuide.com/ubb/mad.gif http://www.PCGuide.com/ubb/mad.gif http://www.PCGuide.com/ubb/mad.gif
Check with Creative to see if this is a known problem as it will probably be a driver fix or possibly just an incompatability issue http://www.PCGuide.com/ubb/frown.gif
Good luck and let us know
