Dear Nick,
dear Otto
Many thanks for your tips! I have tried these steps before asking for
help, but without success.
Then, on reading your mails, it occurred to me I could try one of the
back USB ports of my PC instead of the front ones. And bingo, the USB
stick appeared as 'sd3' in the disk selection dialogue of the step
"Let's install the sets!" :)
On selecting the distribution sets, there is a hint about the missing
'SHA256.sig' file, which makes sense. But I have verified the
downloaded 'install75.img' file as well as compared the SHA256 sum of
the USB stick with the SHA256 sum of the 'install75.img' file. So it is
safe to continue without verification. Correct?
Again, many thanks!
Best regards
Rolf

well...OpenBSD is small, and bandwidth is cheap/free. But yeah, I was
"recycling" back when it was called being "a cheap bastard", I get it.

as you have discovered...no.

correct.

also correct. Besides, rd0 is mounted. But it is also wrong.

dmesg|grep sd
will show you what all the devices are, pick your USB drive. It will
guess
correctly after that.
Or press ? at the right prompt and the installer will show you the
disk details so you can pick the right one.

But here's an easier way, if you understand a bit of what is going on.
The system booted from bsd.rd, and it has utilities in "rd0". At this
point, it is NOT ACTUALLY USING the USB drive. So...you can now
unplug
and plug it back in...and you will get some white on blue text telling
you what device was unplugged and what was plugged in.
Of course, you don't really want to do that if you don't know for
sure that the drive is unused, but if things are as you describe it,
it's safe.
But most likely, it's sd2, because USB devices are enumerated AFTER
IDE/SATA/SCSI/SAS/RAID connected drives. (but there are things that
can happen that keep me saying, "most likely" and "here's how you
find out" rather than just assuming sd2. :) )
