I'm betting it doesn't have an IO-APIC (its a laptop, no SMP, etc) ..
any way to tell if the APIC is working/enabled? (For that matter, all
google could tell me about was the IO-APIC, which is handy to know but
not particularly helpful here.)

Attached (I pulled out the service tag and express service code, both of
which are local to the individual device.)
Also, not sure what (if anything) would be different with the A01 bios;
their changelog seems to focus mostly on fixing a sound bug (which,
unfortunately, I didn't have until -after- the fix... sigh.)
Their changelog is online ( support.dell.com 'small business' ->
'Inspiron 8500' -> 'FlashBIOS updates') but there's not much to it.
