The BIOS version is, yes.

These are the only two pieces of hardware ever reported to have this 
problem. Nobody appears to have demonstrated it on any other HP systems, 
and any non-HP systems would have a different identifier string. With 
the SB400 being superceded, I don't expect us to see any more machines 
with the same ID.
