I have a system with a 64bit SPARC processor. Does the 32bit installation for Solaris 10 support such a system?
There is no 32-bit installation for Solaris 10 on SPARC. There is a single unified installation that provides a 64-bit kernel, and the ability to run both 32-bit & 64-bit userspace programs. Solaris 10 dropped support for pre-64-bit SPARC CPU's, since SPARCs have been 64-bit since 1995.
