IRQ?

[Guest]

I'm having random crashes and freezing in D2exp, and I have read that one possible cause could be something to do with IRQ. However, as I am fairly clueless when it comes to all this technical stuff, what does this mean? How do I go about fixing whatever might be causing problems with IRQ? I read the IRQ advice on thehelper.net but I still don't really understand it and don't yet feel comfortable messing around with this stuff. Any help would be appreciated!

messing with irq's can be tricky and can cause lots of conflicts . best is to look for some 14 yr old wizkid on the block

25 dollars does wonders with those kids nowdays hehe

IRQs are slots on the computer mobo, most computers (newer) have 15, as does ours. You can set in the mobo Bios which IRQ goes with which hardware piece. i.e. vid card with IRQ 7, modem with IRQ 8 and so on =P

sorry that is BS
you cannot assign all irq's thru the bios
if it was only the case it would made my job tons easiers
under win 98 to assign irgs your gotta make a profile

Darthtoast you respond on this forum you better know the answer or not reply at all .

an IRQ (interrupt request query) is a sort of 'code' sent to the CPU to interrupt whatever it is doing. It receives this code from whatever device needs CPU services, and the CPU saves what it is doing and looks up the code in something called a vector table. It then runs the appropriate service routine corresponding to the device that generated the interrupt request. After that it goes back to its 'background' tasks, until it is interrupted again.

In some BIOSes you can set which devices will generate a specific IRQ, but it's usually pretty limited as to what you can set in the BIOS. In the old days, you had to use jumpers or dipswitches to change what IRQ a device uses, but with Plug+Play Windows will automatically assign it and you can edit it manually through a laborious process called creating hardware profiles (in Device Manager).

Actually with my mobo it did work that way. Our modem and vid card were assigned to the same one, and we reassigned the modem to a different irq in the bios. So ha, maybe for you it wouldn't work that way, but for us, it did.

I did try looking up in the Device Management what was connected to each IRQ. In a few cases I had 2-4 devices assigned to one IRQ number thingy. The advice I read said that you could disconnect some devices from the IRQ's with multiple devices connected to them and they would reassign when you restarted. However I can't really tell which things I could disconnect or even how to disconnect them. Some of the devices were listed multiple times and I couldn't identify what some of them were. Should I try to change this stuff or give up on my D2 probs until the next patch?
