We present initial results from an archival study of Chandra ACIS observations of normal and starburst galaxies contained within the Sloan Digital Sky Survey Data Release 1 area. Our goals are to measure the X-ray emission properties of galaxies at z=0.1, and to compare X-ray measures of star formation with optical spectroscopic diagnostics. The initial results focus on the ~100 galaxies with Chandra detections. Their X-ray luminosities are typically <1041 erg s-1 and their X-ray colors are generally consistent with star formation (i.e., X-ray binaries and hot gas). We also comment on the prevalence of higher-luminosity "X-ray Bright, Optically Normal Galaxies" (XBONGS) within the SDSS population. These XBONGS are accreting supermassive black holes which lack AGN spectroscopic features in the host galaxy spectra.
