System IRQ's

[Mike Walsh]

Others posters have stated that the IRQs above 15 are virtual IRQs (i.e. not real hardware interrupts) used by WinNT and WinXP. Since I don't deal much with these OSs I am not familiar with how they work, but I assume the idea is to prevent IRQ conflicts with shared interrupts.

My new PC use IRQ 0,1,3,4,6,8,9,12,13,14,16,17,18,19,20,23

16,18,19,23 for USB
14 SMBus controller.
16 AGP-card.
17 SoundMax sound controller.
18 Network adapter / Ultra ATA.
20 FireWire.
23 SATA IDE controller / USB ICH5

Howdy!

APIC? *APIC* ??

Advanced Configuration and Power Interface

Advanced Programmable Interface Controller. Yes, on P4/Athlon
boards there are typically 24 hardware interrupts if you turn APIC on.

Go ogle. It's ACPI.

APIC is not the same as ACPI. Advanced Programmable Interupt Controller.
Was added when PCI was added. Part of why PCI interupts can be shared.

ACPI and APIC are two different things. Go ogle yourself.

There are 4 entries. NOTHING to do with System IRQ's is mentioned in them.
That would be ACPI.

I know about ACPI. I'm talking about APIC. Two different things.

Advanced Programmable Interface Controller. Why, the P4 at my feet
has one, installed, and therefore has 24 hardware IRQs.

ACPI is Advanced Configuration and Power Interface - not quite the
same thing.

Four? I get 54,200 on "Advanced Programmable Interface Controller",
including (as the FIRST hit) info on the Intel 82093AA. Info at
http://www.intel.com/design/chipsets/datashts/290566.htm .

Try Googling with intelligent choices sometimes. Or better still,
study some. You just might learn something.

not using XP.

15 is the highest IRQ number.

While APIC allows IRQs beyond 16, I don't believe you can have APIC unless
ACPI is enabled. ACPI has been the BIOS configurable option I've seen on the
dozen or so post-APM motherboards I've setup recently (admittedly a limited
sample; ASUS, MSI, ABIT, Intel, and a couple of others), not APIC.

Microsofts info on APIC. Google for "APIC interupt" and you won't get all
the noise of non-related links

I probably sounded like I'm trying to argue that it's /not/ APIC, it's that I
saw advice to the OP about using APIC. I believe the option in BIOS is ACPI,
not APIC; at least it is on the motherboards I've seen lately. You have to
enable ACPI to get APIC.

I in APIC stands for Interrupt, you ****tard. Walph the ****wit Howdyer got
it wrong.

So, what about the shared IRQ lines? Why doesn't the OS just assign
each PCI object its *own* interrupt?

Actually that link is for Advanced Programmable Interrupt Controller
anyway not what he trid to search for.

Just exactly how ****ing dumb are you, snot for brains? Did you even bother
looking at what was written, you know, the ****ing shit you snipped,
cheesestickdick?

**** me dead, some cunts are stupid.

I pointed out that the link does in fact work and it was also
contradicting what the poster was searching for. He said he searched for
Interface controller with that link being the top of the list while that
link relates to Interrupt controller.

Now **** off and learn to read yourself, numbnuts!
