OpenSolaris

OpenSolaris is an operating system kernel.

We're currently evaluating how to boot OpenSolaris via coreboot using the GRUB2 payload.

Build instructions

OpenSolaris has moved to multiboot, so GRUB2 contains all necessary parts, except maybe the filesystem support (ufs compatibility must be checked, zfs doesn't exist yet for grub2).

The instructions on Shudong Zhou's blog don't work anymore, because Sun changed the boot mechanism (again).

what should work (but doesn't for me, yet):

multiboot /platform/i86pc/kernel/unix
module /boot/x86.microroot (that filename might be different)
