IRQ Conflicts???

[John Ryan]

Hi,

I've taken the brave step of building my own pc but I'm regretting it
now! I bought a an Asus A7N8X mobo with a Asus AGP card. In the BIOS,
irq selection is auto so I left it that way. But when Im booting up, I
notice that practically all PCI devices are on IRQ 5 or 11!! And thats
what I think is causing my problem. When installing drivers for Win98,
when sound and display are installed together, the comp crashes and up
pops that hated blue screen!

I noticed that display and sound are both on 5. Would this cause the
problem?? Remember, I left everything to auto and used an Asus VGA
card and mobo so youd think itd sort itself out. In windows 98 device
manager, theres LOADS of system devices like PCI Bridge and IRQ
Steering. Is this normal?

It is the power management. ACPI as I recall. I do not recall exactly how
to get around it. Win 98 and ACPI have problems.

I am sure someone here has a better and more detailed answer.

If not, do a google search on ACPI IRQ conflicts and read up on it. It has
been posted here a few times.

Yep, win98 doesn't share IRQ's real well. IRQ 5 for video seems odd,
normally that's where sound is alone and video in like 9 or 10?. Do you
have PNP OS set to yes in the bios? If so try saying no and see what that
does.

I doubt it... ummm, what problem?

Oh, THAT problem?
Win98 can't use the onboard sound. You "might" be able to hack it to
work, but at a minimum you'll need Win98SE and the Mickeysoft WDM
update, which available from microsloth, or among other places, like
here (or of course a newer version of Windows):

Crashing while the driver installs? Not usually.

Remember, I left everything to auto and used an Asus VGA
card and mobo so youd think itd sort itself out.

It is absolutely irrelevant which make of video card you use, it being
an Asus card has no significance.

In windows 98 device
manager, theres LOADS of system devices like PCI Bridge and IRQ
Steering. Is this normal?

Loads of stuff? There's going to be a "typical" amount as with any
other motherboard, though if you have a board with firewire and RAID,
support for 8 USB ports, sure there'll be more entries than with an
old board having fewer features. Was this a clean install of Win98 or
an already-existing one?

Must admit with ALL the boxes I've built etc, I don't think I've ever
had a graphic card use 5 However depends on what else you are using.

First,, have you tried moving cards around? This usually solves IRQ
conflicts.Have you got a network up and running. These are sometimes a
pain in the neck to solve. Again shifting cards does eventually
resolve this issue. Are you using serial ports? Will you need them?
If not, go into the BIOS and disable them. You've freed up 2 IRQ's
straight away.

The last question, IRQ steering etc...perfectly normal.

Have you downloaded ALL the updates from microsoft?
One other point, have you booted into safe mode. Check to see if there
are any double,treble entries for devices...check everything, HD,
monitors etc etc. If there are, delete all duplicated entries.
Reboot...windows will then go about re-detecting everything as it
boots.

Do not let this put you off,
Is plug and play on or off? sometime itr is best to turn it off and let
the motherboard stick things where it want.
You may have a faulty motherboard, I had the same problem with an Epox
board and i had to send it back.

that is not normal, have a look in the bios and see if the IRQ for
display is on

win98 can be a bit funny with IRQs, the PC steering is something to do
with windows IRQ control.

ah, I just gave up and upgraded to win xp. all the hardware i bought
seem to be directed towards using this in the manuals and bios. its
working great in xp, even though i hate it! by the way, is it easy to
setup apache server and mysql in win xp, or will i just install linux

IRQ sharing is a feature of Win 2000 and XP that works with modern
motherboards that have ACPI power management. It isnt a feature of Win
ME/98/95 and Ive never seen that kind of sharing on a Win98 system. Try
uninstalling your sound/network/modem cards and moving them to differant
slots then boot up and reinstall the drivers. Also when you boot up - go
into bios and disable the serial ports and parallel port if you dont use
them (most ppl have ps2 and usb ports in use but not the older types so why
assign irqs to them). And space out the cards if your motherboard has 5 PCI
slots so there are gaps between and put the sound card as far from the
graphics as possible. Multiple occurences of IRQ steering in the system
information is normal - every device has irq steering next to it right ?
thats okay but sound and graphics on the same irq under win98 is a no-no.
And while I think of it - in the motherboard bios have "PNP OS" set to "NO"
