Beryllium and boron abundances are consistently derived on the parameter scale of two recent uniform stellar Mg and Ca abundance studies, one utilizing non-LTE parameters and abundances, the other assuming LTE. The results are used to explore the BeB-Mg and BeB-Ca relations at low metallicity as urged by B. D. Fields and coworkers. The slopes of all logarithmic BeB-MgCa relations, regardless of light element (Be or B), metallicity tracer (Mg or Ca), or parameter scale (non-LTE or LTE), are found to lie in the range 1.1-1.3. These results using the α-elements Mg and Ca confirm the need for a metal-poor ``primary'' BeB production mechanism (perhaps in addition to standard Galactic cosmic rays) previously inferred from BeB-Fe and questioned BeB-O relations.
