Two primary OBSD partitions on a HDD
I read fdisk(8) carefully (At least I think so), but I repeatedly failed to install two OBSDS on two primary partitions of a HDD. The idea was to realize a multiboot by toogleing the boot-flag to the primary partition of the particular OBSD system I want to boot. However, I think that the install process always chooses the same primary OBSD partition for installation (the first that appears in the table?) and I have no control. /jo

To expand on Tony's comment, OpenBSD uses the fdisk(8) partition information only just enough to locate its disklabel(8). So if you want to have two complete (primary) OBSD installs on a single disk you have to *hide* them one from another. I succeeded in doing just that by using grub's hide/unhide partition feature -- it toggle the partition id of the inactive (other) partition from a6 to b6. YMMV

Hi, Before investigating further, be sure to read the FAQ about i386 disk layout and pay attention to the two very important things there: slices and partitions.
