xenium os 2.0 launch menu question

When selecting where you want to add an item from, there's three choices: tsop, flash, and hdd. Well, hdd isn't yet supported and tsop is just that, tsop. When I selected flash I expected to see my four banks with their respective bios, but instead it makes me select a bios from the hdd. That's fine, I guess. But it seams a bit odd to me. I know it's still beta, but I was wondering if anyone has any input.
