Re: p2b-d high interrupts--looking for acpi guide

got this board free,and I want to install Solaris (working on certification)

I have high # of interrupts on one CPU. this is supposed to be fixable by moving a resistor, but every link I find is down
anyone got one that is still valid or a nice guide

I could avoid it in windows by changing the cpu type ,
but not in solaris

The chip next to the resistors, is an Intel 82093. That is an
"IOAPIC", which is used for interrupt steering. Presumably, the
resistor change does something to that chip.
