Most decent motherboards bought within the last 2 years should allow U to mess around quite a lot with IRQ's Note that some BIOS's require you to enter a keyboard sequence to see the 'advanced BIOS options’. This is typically Ctr+F1, unless you do this you don’t get to see the advanced IRQ type options available in your BIOS. Note also that virtually every MB I’ve played with links PCI slots 1 and 5 together; they share the same IRQ by virtue of the way the PCB is wired – you cannot separate them. The best dedicated IRQ to use is usually one of your serial ports. Disable one or both of the serial ports in the BIOS and dedicate the released IRQ to your Pulsar PCI slot (IRQ 2 or 3). However it shouldnt really be necessary to mess with IRQ's and switch off ACPI mode etc. ACPI should be OK with Pulsar on a modern MB under XP. But see my earlier posting in 'Freezing' re problems with HT and ACPI (i.e. dont use 'multiprocessor ACPI').
