Installing WinXP with manual IRQ assignments?

Due to a serious IRQ conflict between my graphics card and soundcard, I
want to install Windows so that I can choose/manage IRQs manually.
When booting with the Windows-CD, and pressing F5 right at the start of
the setup screen, allows me to select the system I wish to install. The
list of available systems are:
- ACPI Multiprocessor PC
- ACPI Uniprocessor PC
- Advanced Configuration and Power Interface (ACPI) PC
- Compaq SystemPro Multiprocessor or 100% Compatible PC
- MPS Uniprocessor PC
- MPS Multiprocessor PC
- Standard PC
- Standard PC with C-Step i486
- Other
Now, ACPI is the 'normal' Windows option, where XP itself manages the
IRQs. I assumed that I needed an MPS installation in order to change
IRQs myself.
The problem is that when I select MPS Uniprocessor PC, Setup wont
complete. Right after loading all drivers, when the message "Starting
Windows" is displayed in the lower corner, the computer locks up.
I've had a look at the different options in the BIOS, as I read
somewhere that I had to turn off APIC, not ACPI - as APIC was the IRQ
manager.
I found only one option related to APIC; *APIC Mode*, which can be set
to Enable or Disable. When Enabled, you can select the MPS Version
Control for OS, the options here are 1.1 and 1.4. I've tried both
Disabled, 1.1 and 1.4 - all with the same result.
Also, when I disable this setting, my normal XP installation wont
boot.
I also tried fiddling around with the ACPI settings in the BIOS, I
found these options related to ACPI:
- ACPI SRAT (options: enabled/disabled). Default: Enabled.
- ACPI Function (options: enabled/disabled). Default: Enabled.
- ACPI Suspend Type (options: S1&S3 / S1(POS) / S3(STR).
When disabling the ACPI SRAT, the BIOS automatically resets itself on
boot. Disabling the ACPI Function resulted in WinXP setup hanging on
the same place as before. Also, my normal XP wouldn't boot with this
option Disabled.
I also tried hitting F7 at the beginning of the XP setup, which is
supposed to force a non-ACPI installation. Same result here; the
computer hangs when it says "Starting Windows".
Now, does anyone have any advice for me? How can I install WindowsXP
without automatic IRQ assignments?
I hope someone can help.. :)

DFI LanParty nF4 SLI-DR - Bios 06/25/2005
