Can't boot up into Setup -- SOLVED!

[Benjamin Sher]

Dear Miguel and friends:

A million thanks for your suggestion to try another keyboard. You were 
right on the money! I tried a cheap Micro Ergonomic keyboard ($15) and 
instantly my Dell 8200 responded when I hit F2 and opened up the Setup. 
And, imagine, I spent $56 on the Microsoft Ergonomic keyboard at Office 
Depot. Who would have guessed?

So, that problem has been solved.
