In NCAA football, it is a false start when an INELIGIBLE lineman of Team A lifts one hand, or both hands, after having placed one, or both, below the knee (a hand(s) dangling below the knee while the forearm is resting on the knee does not count). A 'covered' lineman, regardless of number, is ineligible. Any player (lineman or back) wearing a number 50-79 is ineligible, regardless of his position, and cannot become eligible until a legal forward pass has been touched by Team B (or an official). And, remember, eligibility only applies to legal forward passes.
