What is the command to check if Solaris x86 or Sparc is installed in your system?
I tried executing uname -a, but i'm not sure if i found the answer.
What does it say?
age:/export/home/vbe $ uname -a
SunOS age 5.10 Generic_118822-23 sun4u sparc SUNW,Sun-Fire-V210
^
i found the answer on sparc. 
in this example, is the highlighted part is the x86?
SunOS servername 5.10 Generic_118855-33 i86pc i386 i86pc
... just verifying..
i found that my answer above is correct.
