I'm wondering if I can change a couple of BIOS settings and would like to know if Asterisk users have experience with these:

"Allocate IRQ to PCI VGA - YES/NO"
"ACPI APIC Support - YES/NO"

Would you suggest setting to NO or are they irrelevant as far as kernel panics by interrupts are concerned?

Thanks,
