What does this mean?

IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 13,
function 0.
Please contact your system vendor for technical assistance.

Go to Start/All Programs/Accessories/System Tools/System Information

From there system Summary, then expand Hardware Resources and finally
IRQs. You should see a list of what device is assigned to your IRQs
and thereby learn or at least get a clue what Windows is nagging
about.

For those wondering a IRQ is short for a Interuption Request. Your CPU
cycles zillions of times a second. With in each cycle devices wishing
to be "serviced" need a way to get the CPU's attention. They can't
shout, or wave their hand or jump up and down, but they can raise a
flag, this will get the CPU's attention the next time it polls the IRQ
lines.

IRQs have a pecking order depending on the importance of the attached
device. The lower the number, the more important the CPU treats the
IRQ. Your system's internal clock, actually the system timer has the
lowest IRQ, (or should) labeled 0 because it helps keep order.

Your keyboard since it usually is the most common way you interact
with your computer should get assigned IRQ 1. In computer speak 0 is
considered a number and is the first number, not the number one.

If you don't see anything listed for IRQ 13, reboot and try to catch
how it got (if it is) assigned in BIOS assuming the IRQ assignments on
your system flash by when you boot, most newer BIOSs show that now. To
stop the display so you can read it be ready to press the pause/break
button on your keyboard.

Wow...

In the old days, there were a maximum of 16 IRQs (0-15).
These ran out quickly, so IRQ 2 was modified to flag the process to use IRQ
9 as a stepping stone to more addresses.

This appears to be gone and replaced with a system that is probably 256 IRQs
(-128 to 127)
Based on the information in Device Manager (and nothing else) negative IRQs
are place holders, (unused?)
There are four of these in my list of devices and each of them are PCI-E
slots that currently do not contain a card.

Amazingly, I am getting four events on PCI slots.

Looking into the problem with Microsoft, they basically state the events can
be ignored if there are no other conditions surrounding the event (they
define this in their knowledge base,) but empty slots should not be a
concern.

So, I'll just ignore the Critical Events on my computer until I put
something in the slot.

Here's a quote I found from the MS Knowledge base on the issue:
"CAUSE
This error message may occur on a computer that uses a Peripheral Component
Interconnect (PCI) bridge that supports message-signaled interrupts but does
not support line-based interrupts

RESOLUTION
This error message may safely be ignored.

Note Do not ignore this error message if the following conditions are
true: . A yellow explanation mark (!) appears next to the device in Device
Manager.
. You receive the following error message in the Properties dialog box
for the device in Device Manager:
This device cannot find enough free resources that it can use. (Code
12)
In this scenario, a different issue may be causing the symptoms. Take
additional steps to troubleshoot this issue"
