Read this:

I believe the patch you need is 104169-08.  You can download it from
sunsolve.sun.com.  Follow the directions carefully.  

With Solaris 7, you also had to change a setting in
/platform/sun4u/boot.conf in order to enable the 64-bit kernel, since:

  # On systems containing 200MHz or lower UltraSPARC-I processors,
  # it is possible for a user to run a 64-bit program designed to exploit a
  # problem that could cause the processor to stall. "

I don't know if you have to do this with Solaris 8, though.
