This is beyond my experience level, but I'd try wiping the disk and
starting over. Try booting your OS X CD, re-running Disk Utility,
delete the partitions, re-initialize the disk, re-create the
partitions.
At that point, you could boot the OpenBSD CD and see if fdisk sees the
partition map. But

Can you show what partitions MacOS thinks is on the disk - that might
gives some clues...
Thanks for the input, my problem is fdisk tells me that the disk “has no valid
signature” and shows the whole disk as unused. pdisk yields a similar input:
“no valid partition map found on wd0 \ Create default map ? Y/N. The question
is, will creating a default map mess up my entire disk now? I.
Yes -- that will erase your current partition map.

I don’t quite get how can I have an operating system running smoothly (Mac OS
8.6) in a disk that has an obviously corrupt partition table ? More important,
most probably disk utility messed up my partition table, so why should I trust
it now to do the job well ? Could wiping the drive out using
I’m honestly not sure. I’m not an expert. But I do believe you need to use
apple’s utility to set up the MBR if you want to run MacOS. You can use fdisk
to initialize the MBR, but only if you want to single-boot OpenBSD
