Hi!
I'm having trouble using installboot. Here some facts that are the way
they are (Test environment on which I simulate things), no need to
discuss them:
OpenBSD4.3 (probably the same issue with any other version anyway)
Hardware is VMWare ESXi 4
Here's what I do:
- fresh install of OpenBSD on a 1GB HD (IDE). Disklabeled all in one
partiton
- Installation is working fine, machine boots OpenBSD fine, everything OK
- next I shutdown the machine and add an additional HD with the exact
same geometry the 1rst HD has. Then I boot the machine again, fdisk and
disklabel it the absolut exact same way I did with the first disk.
newfs, mount it to /mnt and copy /usr/mdec/boot to /mnt. Then I run
installboot:
# /usr/mdec/installboot -v /mnt/boot /usr/mdec/biosboot wd1
boot: /mnt/boot
proto: /usr/mdec/biosboot
device: /dev/rwd1c
/usr/mdec/biosboot: entry point 0
proto bootblock size 512
/mnt/boot is 3 blocks x 16384 bytes
fs block shift 2; part offset 63; inode block 24, offset 936
installboot: broken MBR
It gives me the exact same error all the time: broken MBR. I've tried
that a few dozen times with different HD sizes, disklabel layout and so
on. I have no idea what could be causing this. The only difference
between wd0 and wd1 is that wd1 is connected to IDE0:1 and wd0 is
connected to IDE0:0.
Below you can find the output of fdisk and disklabel for both, wd0 and
wd1. I'd be happy to get a hint what could be causing this.
Regards,
T.
