  A total of $\sim640,000$ objects from LAMOST pilot survey have been publicly
released. In this work, we present a catalog of DA white dwarfs from the entire
pilot survey. We outline a new algorithm for the selection of white dwarfs by
fitting S\'ersic profiles to the Balmer H$\beta$, H$\gamma$ and H$\delta$ lines
of the spectra, and calculating the equivalent width of the CaII K line. 2964
candidates are selected by constraining the fitting parameters and the
equivalent width of CaII K line. All the spectra of candidates are visually
inspected. We identify 230 (59 of them are already in Villanova and SDSS WD
catalog) DA white dwarfs, 20 of which are DA white dwarfs with non-degenerate
companions. In addition, 128 candidates are classified as DA white
dwarf/subdwarfs, which means the classifications are ambiguous. The result is
consistent with the expected DA white dwarf number estimated based on the LEGUE
target selection algorithm.
