ok....I think I understand the difference.  I added it to the defoptions, and 
the default boot didn't boot, the alternate my thinking placing the 
variable at that location, rather than kopt saved me a lot of pain, by 
leaving me a usable login to undo the changes to the default login.  But in 
saying this I'll admit that the envelope of my knowledge is being severely 

Now my real point is that the MP-BIOS error is somehow related to APIC, but 
the suggested solution to add noapic to the boot process caused the system to 
not boot.  I think the issue is fairly rare, was hoping someone could give me 
definite pointers.

Okidokee, I'll look into that possibility.

I didn't think of that you suggested it and I tried it, discovered 
my video card messes up the monitor on the other screens with vertical 
colored lines.....uggh, ATI.  But that is another concern.  Would there be a 
way I could check this from within KDE?
