IBCS2 is in no way related to BSDI.

IBCS2 is a binary interface standard for i386 application programs running
on systems that implement the SVID. The last version I saw (1991) only
specified the COFF executable format and x.out (XENIX) compatibility.

IBCS2 allows us to run SCO XENIX, SCO UNIX, and some ISC UNIX binaries.
