ultra-10 installation problem

	Hello
I am trying to install suse7.3 on an ultra-sparc-10. 
Installation goes successfull, but at the end of setup, silo cannot
write to boot sector. And of course the system cannot boot from disk:a
I dont think that my hard disk have bad sector on the boot sector,
because previously solaris was running on it.

I was previously installed suse7.3 on ultra sparc-5 machines and i have
not experienced this problem.

Is there something i dont know about ultra-sparc-10 machines? (bug or
 a pre-installation task to do?)

Thank you in advance.
