Multi boot question XP and Openbsd after installation

2005-10-09 Thread r.wobben
hello, 

I have installed Openbsd on my computer.
The manual says now for multi-booting with XP you must
do dd if=/dev/rsd0a of=openbsd.pbr bs=512 count=1

but if i do this i get a error-message that rsd0a does not exist

how can i make this right.

Apparently, you are refering to:
http://www.openbsd.org/o/faq/faq4.html#Multibooting

funny, I was just doing a slight update to that section.

It is dissapointing how many people will just stupidly enter a command
line into their computer without understanding what it does.  It is even
more amazing how people will do this when it involves the BOOT LOADER.
MY GOODNESS, do you have ANY idea what you could do to your data?

The new text:
Note: this is a really good time to remind you that blindly typing
commands in you don't understand is a really bad idea. This line will
not work directly on most computers. It is left to the reader to adapt
it to their machine.


PLEASE re-read the very first paragraph of that section (the one
starting with Multibooting is having...) OVER AND OVER until it sinks in.

This is really scary stuff, 'specially combined with some of your other
questions

Nick.

The name of disks is dependent on what type of disk you have. On some
systems, it should be /dev/wd0a; on others, /dev/sd0a; and so on.

See dmesg and /etc/fstab for which disk you have.

Please don't type commands on the console that you don't understand
beforehand. You will want read the manual pages and other
documentation before typing. It will save you a world of pain later
on.

The manual provides an example which you should adapt to your
particular situation, not a cookbook recipe. OpenBSD has excellent
documentation; please use it.

During install, you selected the drive to install OpenBSD onto. Use
that drive. sd0 (or its raw-device counterpart rsd0) is only an
example.


 but if i do this i get a error-message that rsd0a does not exist

In that case, sd0 doesn't exist and you did not install OpenBSD onto
it. Find and use the correct drive. Then things should be fine.


 how can i make this right.

For a hint on what the correct drive is, you can use dmesg(1) or your fstab(5).

Cheers,

Rogier
