Has anyone tried using the "/INTAFFINITY" switch in the boot.ini file to ressolve
the c16 issues with Windows XP?
The switch tells Windows to rout all interupt requests through one CPU, instead
of spreading them out over two. It definitly solves some driver problems
in dual CPU systems.
I ran accross it trying to resolve a problem with a USB card on my Dual Athlon.
I don't have any c16s to try it with, but my testing seems to show that
it puts about 10% more load on the highest numbered CPU, which is a small
price to pay if it solves a driver issue, especially in a dual core or cpu
situation.
Just wondering....
Mike
