On x86/x86, you probably need to run the "installgrub" command assuming
the necessary bits were not installed on installation.
This is a sample usage. Obviously you need to be root.
# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c4t1d0s0
The Sparc equivalent is "installboot". The syntax is a little different
This is a link to an older pdf version of the document. I am certain
that Oracle has a newer one, but MOS is a killer for me to find anything on.
This pdf and the man page should have everything you need to move forward.
Hope this helps,
On the same topic, if there are any current/past developers out there,
where either of the above commands, i.e. installgrub or installboot,
used on the PPC, MIPS, ARM or mainframe Solaris ports? Or was something
completely different used?
