Pros: Great motherboard for visualization workloads. Same issue installing ESXi 5.1. It looks like this motherboard does not support booting GPT disks. Will need to test workaround.

Cons: ASrock. Can you fix the issue with booting ESXi 5.x. Also can users confirm if they have VT-d (passthrough) working on this motherboard?

Overall Review: Great board, need to fix some issues (BIOS Update). Fair price
