Hey, how's that going! You have a similar setup to mine (except freebsd) so let me give you one piece of advice: If you dont want to chainload to the solaris grub, then install the solaris grub first and do the modifications there. If you've already installed linux, you can chainload to the solaris grub, it's not as elegant though.
I've only installed the first two operating systems. Been having a lot of trouble with Windows and logical partitions. Seems to be some trouble with the Boot-Manager.
I've been suggested install Windows Vista (or Windows 7) to a primary partition and edit that boot-manager using EasyBCD then add Solaris and OpenSolaris to the BCD. He said (the guy on the EasyBCD forum) that I can install Solaris and OpenSolaris on logical partitions as long as I have a boot-loader that can 'launch' them. He said BCD would work, and he thinks GRUB would as well. Also been told on another forum that GRUB4DOS should also work.
What are your thoughts on this?
Thanks in advance,
