[OpenIndiana-discuss] [oi-dev] Obstacle to GPT label boot?

[Judah Richardson]

Thanks Toomas. A few questions about that:

   1. Which OI version was originally installed? That would help me
   pinpoint where OI UEFI support landed
   2. What hardware is this on? If it's a prebuilt PC brand and model name
   would be great. If you built the PC yourself, I'd appreciate the brand and
   model of the motherboard
