This feature is new in the Solaris Express 11/04 release.
The Solaris 10 release contains support for the 64-bit computing capabilities of AMD64 and EM64T platforms. This support includes the ability to run both 32-bit and 64-bit applications in the 64-bit computing environment.
For details about supported hardware configurations, see http://www.sun.com/bigadmin/hcl.
The Solaris 10 software already supports these platforms for 32-bit computing.
For more information about Solaris for 64-bit support on x86 systems, see the following references in the Solaris 10 documentation:
