[OpenIndiana-discuss] Hard shutdown now no boot

[Lou Picciano]

Harry, 

First, apologies. I should have provided you that explicit GRUB boot line, then stuck with you! No matter, you're further along now... 

I'm gonna use the Occam's Razor approach, and bet that you've blasted your SATA settings - and that fixing that will be your solution. AHCI and SATA passthrough seemed to do the trick on one of our old Gigabytes; again, settings and naming conventions will vary among mobos. Important in our case was to disable all on-board RAID, however; ZFS is giving us RAID, right? 

Along the way: On a machine a couple of years(?) old, replacing the CMOS battery is a reasonable maintenance item, and simple to do. Just do it. 

Impossible to tell - without knowing the BIOS on your machine - if the screenshot you provided represents a change. 

Hint: Once you do arrive the solution, back up BIOS settings(!) Many BIOSes now have an on-board facility for doing so, in addition to a save-to-media option. 

(This is consistent with advice here from both James and Jason...)

First, thanks for you patience... I realize I am many skill levels 
below the usual posters here. 

>From what I got out of the thread so far. Even if I were to replace 
the cmos bat, there would still need to be settings changed in bios. 
I'm not at all sure what the settings are or how they would need 
changing. 

This image shows the bios screen I suspect contains the settings 
mentioned. Can anyone tell if somekind of reversion has happened? 

zeus.jtan.com/~reader/vu1/disp.cgi 

I believe it as I set it a year or so ago but, of course, I have 
no record of it and the memory is pretty shakey. 

The possible settings at `Sata Emulation' are the one shown: 
RAID+AHCI 

and two more: 

Separate IDE controller 
Combinied IDE Controller 

The more I stare at that... I'm having some vague recollection 
regarding Separate IDE Controller. 

So Maybe it has reverted. 

However being a horrible greenhorn and notorious bungler. I'm a 
little reluctant to change the cmos battery, in case it hasn't 
reverted and changing the battery causes it to. 

I asked in two other posts if it is possible to determine if a cmos 
battery is bad buy some kind of routine test... can anyone speak to 
that? 

The bios clock appears to be maintaining correct time. Not sure if 
that means anything in terms of cmos battery.

OK, thanks. Trying that line just does the same thing as posted 
followed with a spontaneous reboot.

When I edit those out, inside grub, and then (b) boot on the kernel line, it 
fails immediately with an error message I foolishly did not record. 
But apparently temporaryily removing those lines thru grub appears to 
cause an immediate failure.
