  While gamma-ray bursts (GRBs) were once believed to be a dominant source of
astrophysical neutrinos, the lack of any significant correlation between
high-energy photons and neutrinos has resulted in stringent limits on their
neutrino fluxes. Previous IceCube searches for neutrinos from GRBs have
generally focused on the prompt phase of GRBs. However, the higher density
during the GRB precursor stage could lead to more hadronic interactions, and
therefore be the predominant time of neutrino emission. We present results from
an analysis of Fermi-GBM data to identify and characterize individual precursor
flashes. Together with an up-to-date catalog of GRBs, we have made our results
available via an online tool. An IceCube analysis method to search for
neutrinos arriving coincident with GRB precursors has been developed. In this
presentation, we compare the sensitivity of this analysis to previous IceCube
analyses and discuss the implications in case a significant signal is found.
