Boot problems (2.5 OpenBSD i386)

Boot problems (2.5 OpenBSD i386)

Post by hey jud » Wed, 01 Dec 1999 04:00:00



Im a newby to this (supposed very secure) OS. Wanting to see for myself
how much of the hype is really true, I went about installing OpenBSD 2.5
on my box.

When I finally got thru the installation program (no I wont judge an os
by its installation proggie), I said, something to the extent "reboot
and enjoy".

That alone sounded very suspect, cos there was never any mention of
Booting options etc. (linux tells u all about LILO, and asks where u
want to place it.) So my thaught was that, eighter it has now
overwritten my MBR on my primary master (NT resides on that) or it is so
clever that it knows exactly what to do.... (hardly).

Well, I gave it a shot, and guess what, my nt MBR was still there, but
no sign of OpenBSD. So I figured I cna use the bootdisk that I used to
install with various boot options to start off, Is this correct? Can I
pass options to the kernel at boottime?

How do I get the disk to mount my fs on wd1a ? Or must I use some sort
of other bootdisk, or another method altogether?

Thanx for ur help,
hey jude.

this was taken from the OpenBSD faq.

OpenBSD & NT

To multiboot OpenBSD and NT, you can use NTloader, the bootloader that NT
uses. To multi-boot with NT, you need a copy of your OpenBSD pbr. After
running installboot, you can copy it something like this:

        # dd if=/dev/rsd0a of=openbsd.pbr bs=512 count=1

Now boot NT and put openbsd.pbr in c:. Add a line like this to the end of
c:\boot.ini:

        c:\openbsd.pbr="OpenBSD"

You can view this at
http://www.openbsd.org/faq/faq4.html

The faq is always worth reading.

Later.  :)
