[Sunhelp] downgrade Solaris 7 to Solaris 2.6

[Salih DikFesci]

Hi there,

I want to downgrade my ultra10 from solaris 7 to solaris 2.6, because a 
application that I want to install is only supporting 2.6 at the moment. If 
I boot from the solaris cdrom I get the message
boot: cannot open kernel/unix
Enter filename [kernel/unix]:
So I cannot install the 2.6 version
Can anybody provide me with a hint what I make wrong ?

Thanks in advance
Regards Salih
