  We present results from a BeppoSAX observation of the BAL QSO CSO 755,
observed as part of our program to investigate the X-ray properties of highly
polarized BAL QSOs. CSO 755 is clearly detected by the BeppoSAX MECS, making it
the highest redshift (z=2.88) and most optically luminous (M_V=-27.4) BAL QSO
seen in X-rays. It is detected in several energy bands including the rest-frame
21-39 keV band, but we are only able to place loose constraints upon its X-ray
spectral shape. Our X-ray detection is consistent with the hypothesis that the
BAL QSOs with high optical continuum polarization tend to be the X-ray brighter
members of the class. We examine a scattering interpretation of a
polarization/X-ray flux connection, and we discuss the data needed to prove or
refute such a connection. We also discuss a probable ROSAT detection of CSO
755. The observed-frame 2-10 keV flux from BeppoSAX (1.3 x 10^{-13} erg cm^{-2}
s^{-1}) is high enough to allow XMM spectroscopy, and studies of iron K line
emission should prove of particular interest if a large amount of scattered
X-ray flux is present.
