How to get serial number of a Virus KB?
 

Hi there!
I just bought a Virus KB at ebay.
To register at the official acccess virus site, I would need the serial. Unfortunately my KB doesn't seem to have one, at least I didn't find one. (and no, it's not stolen :D )
Is there any other way to find out my serial number?
The access site says I have to hold down 2 buttons while plugging in the power cord, however these buttons don't seem to be present in the KB version.
Do you have any clues?
Cheers,
Barely.
