Applications from any other vendor's standards-conforming 386/486 SVR4
should also run. The main standard being iBCS (Intel Binary
Compatibility Standard).
However, some vendors have made incompatible changes to their
SVR4 release and programs linked on those versions may not work.
Future versions of Solaris 2.x for Intel will address some/most
of those incompatibilities. UNIXWare is one of the offenders.
[From Casper Dik's Solaris 2 FAQ]
Linux binaries will run with the assistance of
lxrun.
