If you add the following to /boot/grub/menu.lst, it will appear in the grub menu.

$ echo “

title Solaris 10 1/06 Single User Boot
root (hd0,2,a)
kernel /platform/i86pc/multiboot -s
module /platform/i86pc/boot_archive

” >> /boot/grub/menu.lst

@Diabolic,

Heh.. glad to know it saved your tons of time :D I do not use any seo plugins or any sort of optimization such as All in One SEO Pack.
