  In this letter, we systematically explore the holographic (non-)relativistic
fermionic spectrum without/with dipole coupling dual to Born-Infeld anti-de
Sitter (BI-AdS) black hole. For the relativistic fermionic fixed point, this
holographic fermionic system exhibits non-Fermi liquid behavior. Also, with the
increase of BI parameter $\gamma$, the non-Fermi liquid becomes even "more
non-Fermi". When the dipole coupling term is included, we find that the BI term
makes it a lot tougher to form the gap. While for the non-relativistic
fermionic system with large dipole coupling in BI-AdS background, with the
increase of BI parameter, the gap comes into being against.
