please help me



i know this is probably a stupid question, but which version do i need to download. i have a serial ata 80 gig hdd. aslo when i download it, what do i do next.
ok, i figured out the right version, but now i have a different prob. i unpacked it and made the floppy, then i restarted the comp w/ the floppy in the drive and nothing happened. it just booted up normally. do i need to do something special. oh yea, i dont think its the floppy cuz i tried 3 different ones.
Change the boot order in the BIOS setup program such that the floppy drive is started before the hard drive.

Run the BIOS setup program by pushing <DEL>, <F2>, or somesuch when the computer is first powered-on.
