Yes. I have a Linux box here with Grub. Admittedly the first
hard disk contains a Windows that gets used sometimes by
other persons. What else should I do? Buy another machine
while I have unused disk space here? Migrate back to Windows
before I try out OpenBSD?

This is exactly what I did.
The first difference appears while partitioning. I quote the document
you told me I should have a look at:
Here is the partition information you chose:
Disk: wd0 geometry: 969/128/63 [7814016 Sectors]
#: id C H S - C H S [ start: size ]
------------------------------------------------------------------------
..
*2: A6 304 103 1 - 968 25 63 [ 2457945: 5349645 ] OpenBSD
..
...
Treating sectors 2457945-7807590 as the OpenBSD portion of the disk.
You can use the 'b' command to change this.
When I run the installation this reads:
Treating sectors 63-120103200 as the OpenBSD portion of the disk.
^^^^
You can use the 'b' command to change this.
Unfortunately, when I use the 'b' command, this won't
change. The partition table is written to sector 1. Not 63.
Not 64. Not 6323185. Not 6323186. I not even find a way to
display that message again after I changed the portion.
The document you pointed to doesn't mention a command to
display what the portion is.
I tried it several times. I booted the CD, ran
disklabel/install/..., booted linux, dd|od'ed the sectors
(there's no od on the CD), re-booted the CD, ...
Yes, I do read documentation and I read it in detail. I
still will be glad if you point me to some new information.
Telling me to read again and again the same doesn't make the
disklabel command behave different. Please do you read the
reports I post in detail.
