Anybody know how to change the irq's on W2k?
all my options are greyed out, but i'm beginning to suspect this might be
the problem with my soundcard (i have sound, just not in games)

Sudesh,

Unfortunately, unless you tell it otherwise, Win2K sets itself up with ACPI
by default - this means that all IRQ's are handled somewhat dynamically,
which is why you can't change them.  I seem to remember there being a way to
change this without reinstalling, but can't remember what it was.

Anybody?

Rick

You may be able to statically assign IRQ's to slots in the BIOS settings.

You also can try swapping slots on the motherboard. Your motherboard book
should tell you what slots are shared as well so that may clear things up.

To remove ACPI go to control panel->system

Select the hardware tab, and device manager.

Underneath the 'Computer' icon, you should see the ACPI thingy. Right click
properties, and select driver.

Select update driver, and display a list of known drivers. Select show all
hardware of this device class, and look for

(Standard Computers), Standard PC.

Thats the one you want.

Win2k shares the same IRQ for everything unless you force it not to.

You should also match this in the BIOS (if supported) by
turning OFF the ACPI aware operating system option.

Bear in mind, without ACPI you will not have control of
hardware resources from the operating system, so any
IRQ changes you need will have to be a slot change or
modification to the BIOS config.

Win2K uses ACPI, and controls all of the IRQ's for you.  Having multiple
devices on the same IRQ under Win2K/XP is absolutely normal and expected.

The only time this causes problems is when there incompatible drivers or
hardware installed.

There is a way to run your system as a "Standard PC", in which case you can
modify these things yourself, but it requires reinstalling Windows 2K and
it's not really recommended.

The way of changing this without reinstalling is frowned upon by just about
everyone, including Microsoft, who saw it as so much of a problem that they
wrote a Knowledgebase Article saying "Don't Do It!".

It is highly problematic, and a complete waste of time.

This is a BAD idea.  It has caused headaches, in one form or another, for
nearly everyone that does it (whether they admit it or not).

The main problem is that your system is built with a particular HAL
configuration when Windows is installed.  By manually changing from ACPI to
Standard PC, you don't have the proper matching HAL in place.

It gets ugly from there for most people.

Also power off the computer, either by the switch on the back (power supply)
or by pulling the power plug. As I have found that Win2k does not recognize
some hardware/IRQ changes with a simple restart or power cycle from the
front panel switch. This will all depend on if your motherboard has Wake-Up
Support, i.e. Remote Ring On.

Thats a lot of postings there Larry. I didn't recommend doing it. The poster
simply asked how it was done.

I have done it, and its resolved IRQ contention issues I had between my
realtek network card, Geforce AGP card, USB and everything ***y else being
all on IRQ 9. I got unreasonable crashes every hour or so. Now I don't.

Seemed to work for me.

Where did you get all your information from Larry? Any references from
Microsoft on this? Any pages where its mentioned how bad this is?

What I'm saying is, your milage may vary. Don't take my word for it - but if
your machine is not working anyways...... whats to lose?
