All my PCI and AGP cards share the same IRQ!

[Winger300 0]

Running an Abit BH6 with ACPI enabled, and latest Bios.

 

Just installed windows, and im having some problems with the sound card drivers (Aureal Vortex 2)

 

 

The applications crash out with an error "The instruction at (address) referenced memory at (address). The memory cannot be read."

 

I think this is caused by the fact that every card in my system is sharing IRQ 7!

 

Thats the Geforce, Diamond Supra express modem. Realtek network card and Diamond MX300. All are using latest drivers.

 

I have enabled "PNP OS installed" in the bios and it makes no difference. I cant change the irq's manually from Device manager either.

 

Any ideas what i can do to sort this?

Pop along to both Microsoft & Intel's web pages.

Do a search for ACPI.

You will find that the fact all of your hardware devices are sharing the same IRQ is not an issue, this is ACPI working correctly.

However this can all go to pot if some part of your system isn't fully ACPI compatible, have you checked to see if there is a new updated BIOS for your motherboard?

I have the latest motherboard bios. I think its most probably my soundcard which is causing the problem as the drivers aren't very stable and it seems to be the Vortex control panel app which always crashes.

 

So how can i get my devices onto seperate IRQs? and still be able to use Hibernation?

 

I used to have it running perfectly. How about if i disable ACPI, re-install Win2k then enable it in the Bios. Will Windows detect ACPI and allow me to hibernate?

I re-installed Without ACPI, all the devices are on their own IRQ now and its still happening.

 

Only thing i can think of is that the Bios im using is incompatible.

Is there a way you can set up Win2k to NOT use ACPI when you install?

[Winger300 0]

Yeah, ive sorted it. It seems that my Modem's Wave driver was conflicting with my soundcard. Disabling the Modem wave driver fixed it.

That's just it.

When ACPI works it is excellent.

No worrying about devices conflicting or worrying if that new piece of hardware will be able to find resources inside your PC.

With ACPI the traditional 16 IRQ's is banished as everything quite happily displays itself as working on the same one.

When ACPI doesn't work everything goes to pot - As you have seen.

Pester your motherboard manufacturer for a fully ACPI BIOS for the board your using.

Win2000 advises to set PnP Aware OS to no. It doesn't make any sense to me either, but that's what MS suggests.

Yeah, i got everything working now, but ACPI seemed to not be causing any problems then. Sounds a good idea because i do have a shortage of IRQ's. Is there anyway i can enable ACPI in Win2k? once its been installed without it?

[Gerbache Kaznet 0]

Well.....

There is a way to get ACPI turned on without reinstalling, but there is a pretty decent chance that you'll kill the install. You go into device manager and change the drivers for standard PC to ACPI PC. If this works, you'll reinstall all your drivers and all will be happy with the computing world. If it doesn't work (like mine, I might add) your system will not boot, and you'll have to totally reinstall Windows from scratch. Personally, I'd say just reinstall it if you only recently installed it anyway. If you really want to chance having it screw up, go for it, but it's more of a hassle than it's worth IMHO.

I think it's something funky with the Intel 815E chipset. When I poweron, I can see all my irqs are different, but when I actually get into Win2K Pro. It tells me they are all on IRQ9 which is bogus according to the bios post. I haven't figured out what is screwy in Win2k yet.

[Dragon-Lord 0]

That behavior is correct. The bios post should show different IRQs, but when ACPI under Win2k does its thing, they should all be one device (usually 9 or 11).

 

In fact, since my flaky supermicro P6DBS v1.02 board reported IRQs from 1 to 20, I took it as a good sign when my new Abit BE6-II v1.2 booted up for the first time with everything in it and sure enough all my PCI cards are on IRQ11...and not a hiccup or crash yet...

 

The new $120 board has already blown the old $450 one away...sad sad sad.

This is not an specific intel 815 chipset issue. In my asus p5a, when I boot, all my devices are asigned an irq, but when I boot in windows 2000, they all share irq 9.

 

Anyway, this ACPI irq sharing issue is not a problem for me. My system works stable and smooth, with and without irq sharing.

Yeah, I did a little more research as well. Once Win2k boots up with a fully complain ACPI motherboard, it'll use the IRQ steering feature to assign all the pci cards the same value (Usually 9). It ignores whatever you set in the BIOS which is kinda funny, but I haven't actually had any problems either. Everything is great.
