Few simple questions about FreeBSD

[Sharma, Tarun]

Hi all,
I am a new user for FreeBSD operating system. Can anybody 
tell me answer for
these questions:

1. what all steps does FreeBSD takes when it gets start. I 
mean it reads from ROM and then loads the operating system etc etc.

2. Does freebsd kernel supports thread architecture. If yes 
then how ? I know about sunOS and it supports threading. 


Thanks
