Hi all,
Any way to boot Solaris from grub2? I mean: don't use something like
rootnoverify and makeactive
but write at  the end of linux menu.lst something like

root (hd1,1)
kernel /boot/platform/x86/kernel/unix
module /platform/x86/kernel/boot_archive

Can grub2 load solaris 32 kernel?

-- 

Best regards,
Alexander

That's grub1 syntax. In grub2 you have to specify the kernel type when
loading, i.e.: "linux /boot/vmlinuz" or "multiboot /boot/mach.gz".

Is Solaris Multiboot-compatible? If not, you can try to use its own
bootloader through the `chainloader' command. However, if grub1 could
load it with "kernel", either there was a specific loader for it or the
Solaris kernel was compatible with one of the grub1 loaders: try with
all the grub2 loaders (multiboot, bsd, linux) and only then resort to
chainloader.

You (or someone else) can also try to either port the grub1 Solaris
loader (if it exists) or write a new grub2 loader for it but I don't
know if the latter would be possible without specs. Besides, in order
for such a new loader to be incorporable to the "official" grub2, the
development process must follow some guidelines in order to avoid future
legal problems, like "no reverse engineering" (maybe clean room
techniques are OK, but I don't know the FSF policy) and so on.

It's multiboot compatible, but with a broken multiboot header (defines 
a.out kludge while being ELF), I reported that issue, no idea when they 
catch up.

And when this is worked around (I patched out the test in grub2), it 
still doesn't run, maybe because some tables are missing in grub2's 
multiboot implementation (e820? no idea, didn't investigate further)
