Thank you everyone for your interest and help, I am finally home so I can explain the situation and my frustration a little further:
I partitioned my hard drive using the Disk Utility in the MacOS X live CD. I created two equal HFS+ partitions. I successfully installed, and regularly run, Mac OS 8.6 in this first partition. I want to install OpenBSD in the second HFS+ partition, so I can double boot. Following (or trying to follow) the MacPPC installation instructions, I created a bootable OpenBSD 62 install CD. At the installer, everything goes fine until I get asked if I want to use the whole disk, which I do not, so fdisk is summoned. The problem is, the very first thing that fdisk tells me is "MBR has invalid signature, not showing it". So I choose "edit", to which the installer responds printing a completely empty disk layout with partitions 0 to 4 all marked as "unused", which is BS because my disk is, as stated, running 8.6 with no problem. This is what freaks me out. Trying to summon pdisk from the shell does not help much, either. Am I missing some step? doing something wrong? freaking out for reason? Thanks a lot in advance! Raymundo.-
