friggin win2k IRQ issue.

[crosstudio]

i upgraded to win2k so that sonar's latency will improve. now friggin' windows has set my soundcard, ethernet card, and ata100 raid to IRQ 11.

anyone know how to change these settings other than physically switching the cards on the motherboard?

Win2k supposedly works best with most everything on the same IRQ. If everything works then there's nothing wrong with this, that's just the way its supposed to work. If you want or need to change this, go to device manager, go to computer properties and change it to non-ACPI (I'm doing this from memory since I'm booted into my WinME partition at the moment but its something like that). Win2k will need to copy a few files from the CD and reboot. You may also have to disable ACPI in the BIOS. After all this, Win2k should give everything its own IRQ. You lose a few power management options by doing this but I think there's a way to set that up manually.

Good luck!

thanks from the ACPI driver to Standard computer worked

The driver options are:

ACPI
dual processor ACPI
multi-processor ACPI
some kind of MPC something or other
Standard Computer

my problem is that my ATA100 RAID driver, and etherfast card are causing pops on my audio card, which wasn't happening when the IRQs weren't sharing, so I changed the driver to "Standard computer".

win2k and cakewalk

Crossstudio,

Your problem might be due in part to the following....Win 2k (w/oservice packs) has a problem with the ATA100 using DMA. You can get a patch fix from MS that will take care of it (search for doc. Q260233 at MS. The fix may also be included with Service Pack 2 which is now out. Without this fix you get skippying, pops and clicks because you are not utilizing DMA which improves audio performance significantly.

hey, thanks for the info. i'll get the service pack when i get home this weekend... consulting is such a pain in the a** sometimes.
