Turn off ACPI and APIC and then enter the IRQ assignment menu (YES ITS GOT ONE but those Nvidia crapsets dont have them!!) then use this menu to assign the IRQ's you need for UAD cards and soundcards. Rebuild windows and before hand turn off ALL the com ports and printer ports and any uneeded USB ports, dont forget you are able to use a USB hub. Replace the Nforce board with an ASUS A7V-X KT400 Chipset board. This is the bit were some schmuck tells us that its the nuts just because hes got one.
I can tell you without any fear of fiction that a DAW with those components AND an Maudio Delta driver card will never work well at low latency and may always pop and click.
Because of the numerous registry and system file changes required, you must rerun Setup (an upgrade installation does not work)."
To disable or re-enable ACPI, you must first change firmware settings and then re-install Windows XP Professional to avoid a Stop 0xA5 message or a Stop 0x79 message. Some x86-based systems enable you to toggle ACPI functionality. "Because systems that use the ACPI HAL ignore IRQ assignments stored in firmware, you are only able to manually change IRQ settings for non-ACPI (Standard PC HAL) systems. Here's the hassle about swiching back to ACPI: If Standard PC is shown in the list, choose it, otherwise untick Show compatible hardware, then select Standard PC from the list. Select "Don't Search, I will choose the driver to install.", click Next.
Select Update Driver, then choose "Install from a list or Specific Location (Advanced)", click Next. In Device Manager, expand "Computer" and right click the expanded entry. In order to manually assign IRQs, the Hardware Abstraction Layer (HAL) must be changed to Standard PC with APM support. If your system is ACPI compliant, then ACPI will assign the IRQs. ACPI establishes industry-standard interfaces for OS-directed configuration and power management on laptops, desktops, and servers. ACPI (Advanced Configuration and Power Interface) is an open industry specification developed by Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. If you are unable to resolve your IRQ conflict, you may need to assign IRQs manually. I also found this on the internet (however I remember reading somewhere that once you put a PC in "Standard PC" mode, you may not be able to put it back into ACPI mode, or was it vice versa): From a book I have it says that PCI slot 2 (counting from the left, which left? I don't know) is assigned to IRQ 5 and PCI slot 4 is assigned to IRQ 9 or 10. I'm pretty sure that IRQ's are assigned based on those slot locations. Try moving your 2 cards into different PCI slots but especially physically as far away from each other as possible (but not near an AGP graphics card if you're using one). Or am I better off re-loading windows as a non-ACPI install? Will that allow me to assign IRQs?
Will a different graphics card provide better results? Any preferences here? Which is preferable? In preliminary tests, it appears to work better if the graphics card has its own IRQ. I can get my graphics card or my audio card on their own IRQ - but not both. Likewise, XP doesn't seem to allow you to assign the IRQs. I've tried making changes in the BIOS but they don't seem to have an effect in XP. Is there a way to assign PCI cards or other system devices to a specific IRQ in Windows? It only seems to change as I move PCI cards around. PCI latency settings don't seem to make a difference. I'm trying to cut down on my pops and clicks and have read tons of threads here about doing so. Floppy controller, COM, Parallel, On-board audio, SATA controller all disabled in BIOS.
