System IRQ's

[Jerry G.]

I am looking at my system in both system information, and in the computer
properties.

I cannot see the following IRQ's: 3, 5, 7, 11, and 17. I am very
curious to know why Windows did not assign them, and doubled up others to be
shared?

The second thing is that I cannot seem to figure out what USB device is on
what USB Universal Host Controller. Each controller has a set of ports in
association with it. I found the Host Controller addresses.

What I want to do in the end, is to determine exactly which USB device is in
which port when viewing it in the System Hardware Properties.

It turns out that one of the USB Host Controllers is being shared in IRQ
with the ATA hard drive. Another Host Controller is being shared with a
modem. There is another one that is being shared with the video display.

I have an HP 4670 Scanner, and it is giving loss of communications problems
because of the IRQ sharing. I found this out after doing a lot of searching.
To get around that, I used the USB Host Controller that in shared with the
least demand. This was the one that is shared with the modem. The scanner
was now, only failing to communicate once in a while.

To resolve the issue, I added an active USB hub to act as a type of buffer.
It actually is slowing down the USB communications. With this approach, the
scanner seems to be working for now. I tried it many times over the coarse
of the evening, and it has not failed yet.

What I am looking for, is if someone would have an explanation for this???

I won't pretend that I have a comprehensive view of this either. Here
is some dated information, however, for what it's worth:

No, Windows 2000/XP can assign virtual IRQs. Example from the computer I'm
in front of:

IRQ 18 - ATI Capture Card
IRQ 19 - GF4 Ti4400
IRQ 20 - 2 10/100 NICs (a 3com and an nVidia), 2 nVidia audio devices, a
firewire controller, 2 USB controllers, and the PCI to USB controller.

There are only 15 /physical/ IRQs

It's a BIOS problem, more than likely. You will need to go into the BIOS and
see what resources are shared, then you'll have to force an IRQ in the BIOS.
For example, PCI slots are often shared with chipsets and USB ports. You'll
have to poke a round a bit, moving things from one slot to another, but
that's more than likely what is causing the issue in the first place.

LOL. Shows just how right your conclusions can be.

Same problem here... my modem is sharing IRQ with nothing (it seems) but it
still says the IRQ is shared!

Check the BIOS to see if the IRQ setup is configured to be automatical, and if
there's 'Assign IRQ for VGA' enabled. I've had similar problems with my modem
(slow connection, blue screen)

This pertains more to win98 but may provide some help.

There are 16 IRQs (15 usable) in a computer system. Here is a typical
assignment of these IRQs:

IRQ 0 System- System Timer
IRQ 1 System- Keyboard
IRQ 2 System- Cascadeable PIC (programmable interrupt controller), controls
IRQ 8-15
IRQ 3 System- Serial Port (COM 2 and COM4)
IRQ 4 System - Serial Port (COM 1 and COM3)
IRQ 5 Available- General Adapter Use
IRQ 6 System- Diskette Controller
IRQ 7 System- Printer 1
IRQ 8 System- CMOS Real-time clock
IRQ 9 Available- General Adapter Use
IRQ 10 Available- General Adapter Use
IRQ 11 Available- General Adapter Use
IRQ 12 System- Mouse Port
IRQ 13 System- Math Co-processor (even though this is built into the CPU, it
still uses an IRQ)
IRQ 14 System- Hard Disk Controller
IRQ 15 Available- General Adapter Use



As you can see, there are five (5) IRQs that are not assigned by the system
design. Of these, one usually goes to the graphics card, one to the USB
ports, and one to the modem. That leaves two (2) available IRQs for
everything else. With care (and use of the proper cards), this is normally
sufficient.



Loading Sequence for Additional cards:

First:
Internal Modem (PCI)
Second:
Sound Card (PCI or ISA)
Third:
Network Card, a.k.a. NIC (PCI or ISA)
Fourth:
DVD Devices requiring Dxr3 Decoder Board (PCI)
Note: Some video decoder boards require two (2) IRQs for complete
functionality. Check with your video decoder card manufacturer for video
decoder support and requirements.
Fifth:
SCSI Adapter (PCI) (This assumes that the system does not have a SCSI hard
drive.)
Sixth:
Any others.

For my own part, I have never had a thought which I could not set down
in words with even more distinctness than that with which I conceived
it. There is, however, a class of fancies of exquisite delicacy which
are not thoughts, and to which as yet I have found it absolutely
impossible to adapt to language. These fancies arise in the soul, alas
how rarely. Only at epochs of most intense tranquillity, when the
bodily and mental health are in perfection. And at those weird points
of time, where the confines of the waking world blend with the world of
dreams. And so I captured this fancy, where all that we see, or seem,
is but a dream within a dream.
