Any help would be greatly appreciated. I have an Openserver 5.0.6 system
that has been running smoothly for years. This morning, an employee who
shall remain anonymous (not me), decided arbitrarily that the system was
running slow and should be restarted. He **did not** do a proper
shutdown,
he just turned the machine off. Since this time, the machine hangs just
after "Verifying DMI Pool", and I never get a ":boot" prompt. I can,
however
boot from a boot floppy by entering "hd(40)unix" at the boot prompt.

I have tried to restore the boot block by running the following:

dd if=/etc/hdboot0 of=/dev/hd0a
dd if=/etc/hdboot1 of=/dev/hd0a bs=1k seek=1
dparam -w

which did not change a thing. I then tried:

instbb hd /dev/hd0a
dparam -w

which also did nothing. Still no boot prompt from the hard drive.

Any suggestions?

Thanks in advance,
Steve

Fsck /stand? are the /stand binaries corrupted? (btmnt -w) I'm pretty
sure that if /stand is hosed, you will not see the boot: prompt.

Well, when I try to run fsck on /stand, it complains that "/dev/boot a
mounted filesystem, ignored"

umount /stand and then fsck /stand gets an error of "fsck: `/stand` is not a
mounted filesystem"
"fsck: could not get device for /stand"

I also tried "btmnt -w" and then "fsck /stand" with the same results.

I had limited sucess by moving the hard drive to the secondary IDE
controller, and it boots there, but then I lose the cdrom drive. Thought
maybe it was a hosed primary IDE controller on the motherboard, so I swapped
motherboards (I bought two of the same board when I put this machine
together several years ago just in case), but have the exact same results
with a brand new motherboard, so I don't feel like it's a bad conteoller.
When I install the cdrom drive on the primary controller, and the hard drive
on the secondary, it boots, but I immediately get a kernel panic and
shutdown. Remove the cdrom and leave the hard drive on the secondary
controller, and it boots fine again.

I guess losing the cdrom is not a big deal unless I have something to
install that is only available in cd media, but I just don't like things not
being right.

Sorry for being so verbose with this, and thanks so much for all of your
responses so far. Any and all suugestion are welcomed.

Steve
