well going over the manual, it looks like yes you can set smaller jumps to the FSB manually, but I see nothing about locking the PCI bus, so no mater what, you will be overclocking all your other components besides the CPU.
as for win2k, its out there, but I cant help you find warez, even though you do have a license, not on this board, keep looking, have you ever used bit torrent, there are tons of things on bittorrent. If you haven't read up on it here:

The system would be nice for a file server, 1 primary IDE, 1 secondary IDE, and 2 more on the promise RAID controller. You don’t need to use the RAID controller as a RAID, so you can have 8 hard drives in the system. Then if you still need more, you can stick another RAID card in a PCI slot. at that point it would be pretty tapped out, but that’s 12 drives or so. Just make sure that the PCI slot you use have the NIC in is not shared by any of the drive controllers.
