if you want to inject a Perc 5 or Perc 4 driver inside a windows (the real one, not bartpe), i added these features to the famous VMSCSI plugin for BartPE:
Useful to restore a server on another hardware:
-boot with bartpe
-restore with ghost or another tool
-inject the Perc5 or Perc4 driver in the windows you restored with ghost
-reboot, it's working out!
If you are restoring from another hardware (a good reason to inject different driver !), you may need to do a fixmbr : mbrfix /drive 0 fixmbr /yes
