The Petitboot Linux kernel doesn't understand the OpenBSD's disklabel. So what the installer does (if you select "(W)hole disk") is create a 0C FAT partition and an A6 OpenBSD partition. The FAT partition is used to store the OpenBSD bootloader and a GRUB-style menu.cfg that tells Petitboot that there is a bootable OS on the disk. I don't see the FAT partition in your fdisk output, which makes me suspect that you follwed the "(E)dit MBR" path instead. In that case your on your own and if you don't create a FAT partition the disk will not be recognized by Petitboot. Cheers, Mark
