My card has both IRQ 7 and 10 free.

Still Winodows 98 puts both soundcard, on-board network, two USB
controlles and USB 2 hub on IRQ 11 :-(

I have tried all things, enabled/disabled PNP-OS in BIOS, checked both
"Use hardware" and "Use BIOS" under "PCI bus" in Device manager.

When system boots the BIOS selects IRQs that spreads the devices most
on the BIOS bootup display, but Win98se changes this to the same setup
each time, not using 7 and 10, but putting severalt things on 11 :-(

Any tips ?

I don't quite like having sound, network and 3 USB on same IRQ
(if I select manual setup, which one sound get it's own IRQ ?)

(don't like having AGP and one USB on same either, but that is
hardwired on the MB so I can't do anything about that anyway :-)
 
Even worse. I can't use manual settings for anything.

If I uncheck the "Use automatic settings" for a PCI device (like
sound, AGP-card, network or USB) there is only "Basic configuration
0000" available, and if I try to double-click any settings (like the
IRQ used) I get a "This resource settings cannot be modified".

But I get this on all PCI devices and cards - no alternatives...

What has happened, and how do I get i back to normal (so that the
devices is spread out on all available IRQs, and I can manually assign
IRQs - it used to work OK earlier, something must be messed up :-)

Question, why are you still using Windows 98?

I use XP at work, That's why I use 98se at home :-)
(XP is slower, more games/programs not working etc)

But that's a bit off topic, as the device handling
is quite similar in XP. Still: What has happened ?
 
That's probably ACPI working, which puts them all on 11. There is nothing
to worry about, if you aren't having any problems.

As Anthony R said, that's normal for an ACPI machine and OSes that support
it.

But when I specificly allocates certain IRQs to certain PCI slots in
BIOS setup, why does it then still move them around :-(

I can't be good to have both video, sound and network on same IRQ ?

BTW: If I select "plug-n-play OS: no" in the BIOS the same happends,
but at boot all devices get their own IRQ in the BIOS listing
(and for some reason Windows starts faster, strange, it dosn't
use those settings anyway - anyone have any clues :-)

I don´t know what OS you´re using, but in W98SE I can select ->device
manager-> system devices-> PCI bus. Then Select "hardware" or "BIOS".
You can also check the "IRQ steering" tab in "PCI-bus".

To be honest: I´ve got also problems with this: al lot of IRQ´s are set to
9. Also due to the amount of IRQ´s the USB-drivers need.........:(

Didn't help choosig BIOS, but I disabled IRQ steering, rebooted, and
then enabled IRQ steering again, and now the devices are more "spread
out" on all IRQs. Might have been on one beacuse I disabled lots of
devices and installed new, and it didn't reuse the unused IRQs then,
but when ALL devices where rescanned it somehow did things better :-)
