Re: [FIXED] Re: Messed up OpenBSD boot after dualbooting via grub - cannot boot without OpenBSD boot CD.
The 128G limit usually means from the beginning of the disk. I also use chainloader +1 for booting BSDs from x86 machines. Apologies for keeping the thread alive. --- On Sat, 3/26/11, Amarendra Godbole wrote: From: Amarendra Godbole Subject: Re: [FIXED] Re: Messed up OpenBSD boot after dualbooting via grub - cannot boot without OpenBSD boot CD.

[FIXED] Re: Messed up OpenBSD boot after dualbooting via grub - cannot boot without OpenBSD boot CD.
Okay, seems like I sent a hasty reply earlier.
Got this fixed, by booting off a 4.8 CD, and "upgrading" - fsck all
filesystems, say no to bsd, bsd.mp and base, it created device nodes,
and congratulated me for completion of the upgrade. Rebooted, and the
system came up nicely.
Noticed two things:
(a) the * after hd0+ is gone during boot>
(b) the disklabel now shows proper values for "boundstart" and
"boundend" - earlier both were 0.
Thanks to all those who replied. Now I am off to reading more about
boot, and friends (though I am not sure if things are well at this
point!).
