What is the slice layout at those disks?  Is it one small EFI boot slice
(pcfs) + one big slice covering the rest of the disk and used for rpool?
If I'm not mistaken this is the default layout created by the OI
installer when installed on GPT/EFI disk (without MBR).

Is there a way to install OI on a GPT disk in a slice not covering the
whole disk?

Legacy BIOS?  Is your system really able to boot in legacy BIOS mode
with the rpool as outlined above?


Thanks.
