We have obtained FUSE spectra of 6 eclipsing binary systems containing O and B stars. The aim is to improve the accuracy of the temperatures and/or luminosities of these systems for which the masses and radii have been well-determined. We present the results of the comparison of the FUSE continuum for several of the systems with standard star spectra to quantify the temperature and also explore the luminosity sensitivity of the 920 to 1100 Å region. Stellar atmospheric models, existing IUE spectra, and visual photometry will ultimately be used to obtain highly accurate temperatures for these stars, including V380 Cyg (B1 III). Funding for this investigation has been provided by Chandra contract NAS8-03060 and NASA grant NNG04GM87G.
