[LinuxBIOS] MSI ms 7250 (based on Giga57Sli) none SMP kernel IRQ problem

[George V. Adamov]

If I understood correctly it's possible to change IRQs for pci slots via 
mp_table.c  /*I have a dual core CPU 3800+ but running LB linux with smp 
kernel shows only one cpu (((*/
But when booting none smp mp_table seems to be ignored (as well as 
pirq). Is there any way to control interrupts assigned to PCI slots? 
/*should I programm interrupt controller directly*/

Well, not arbitrarily. Which IRQ you can assign to a PCI slot is
ultimately determined by the signal routing on the mainboard.

This sounds bad. Does LB say anything about multiple cores? (Should
it?)

This also sounds bad. Is there ACPI for this board? That would cause
mptable and pirq to be ignored by Linux.

Not arbitrarily, no. :\
