Solaris 2.5.1 CDE
FYI for anyone trying out Solaris 2.5.1 x86 or SPARC, the library copies are missing the Desktop CD which contains CDE and WABI, but you can use the one from the PPC release; the desktop CD has all the platform versions (all of the 2.5.1 platform media kits contain the same 704-5275-10 Desktop CD)
