Is it necessary to reinstall OS upon motherboard change?

[Manish Jain]

Hi,

Because of certain problems I am experiencing with my hardware, I am 
planning to move to another motherboard + CPU. Just out of curiosity, I 
wished to enquire - is it possible to use an existing FreeBSD 
installation despite change of MB + CPU ? In the Windows world, that is 
pretty much impossible, but on FreeBSD the possibilities don't appear 
that bad to me. (My hard disk and graphics card will remain unaltered).

Thanks for any inputs.
