FreeBSD/sparc64 on SunFire V100 [URGENT]

[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 it supports threading. 


Thanks
