  We continue the survey initiated in arXiv:2012.14197 to explore the
Bethe/Gauge correspondence between supersymmetric SO/Sp gauge theories in
2d/3d/4d and open spin chain with integrable boundaries. We collect the known
Bethe ansatz equations of different types of spin chains with general
boundaries that have been analyzed in the literature, and compare them with the
vacua equations of the quiver gauge theories. It seems that not all the vacua
equations of quiver gauge theory with BCD-type gauge groups can be realized as
some known Bethe ansatz equations of integrable spin chain models.
