OK now I've got a problem
My stupid board likes to share multiple devices with 1 or 2 IRQs. The sound/video are one 16 and the SATA controller/LAN are on 19. So I guess Gigabyte and Microsoft claim that this is OK and it happens. Well, my computer and BF2 say this is NOT OK. It no likey sharing IRQ's. So, I want to change my IRQ manually, but XP won't let you. I read that if you goto Computer and reinstall ACPI to Standard PC, you can manually set the IRQs. Well, I tried that and now...Boom, Windows doesn't load. Now I'm going to have to try a repair install and hope things aren't screwed up. But in the meantime (I'm on my gf's comp)....Anyone know a way that WON'T f***my computer up to assign IRQs?
All I can do in BIOS is assign PCI slots to IRQs or set some IRQ's 'reserved' and I'm not sure what that does. Either way, it looks like Windows ingores that setting anyway.
I read that the IRQ assignment can only be altered during Windows installation by hitting F5 or something of the sort? Please let me know if you guys know anything about this junk! THanks in advance!

Ah damn, looks like I'll have to full reinstall Windows (AGAIN) to load the Standard PC / F5 thing. I've read some people have luck with this, and some don't. Also, when I do this, do I have the option to hit F6 again at some point to load my sata drivers?
 
Ensure that "Plug and Play OS" is set to disabled in BIOS. Sharing IRQs is normally not an issue... if you were having problems, driver updates and possibly a BIOS update would have solved your issues.

Going from ACPI to Standard PC won't let you modify your settings manually, either. What you have to do is disable APIC mode in BIOS... but this does require reinstallation of the OS. I have yet to have an issue with APIC enabled.

Aye, I did a few driver re-installs and try to move thigns around, I have the latest BIOS. I've had these issues before, especally with BF2 because its a very touchy game. The IRQ Not Equal BSOD is usually a sure giveaway of an IRQ issue.
Unfortunately, I don't think I have the acpi option in BIOS, I looked around for it to no avail.

to get the advanced bios options in a gigabyte bio screen, hold CTRL + F1 when you're on the main bios screen and you'll get some hidden options, but IRQ management has sort of been disolved now as it's all done automatically

but if you had an issue with irq conflicts, you'd see a flagged device in device manager
