Installing a third party SCSI or RAID DRIVER

I recently forgot my admin password, and i was given a software in a start up disc to unblock the admin account but this as to be done using windows 2000 or Xp with boot up capacity, i’m supposed to install this password software at the step where it says to install a third party scsi or raid driver press F6, when i press F6 to change the cd nothing happens the win installation just goes on. Can any one help? How do i get to next step if F6 does not work i also tried different keyboard any solutions?
