Unable to boot normally - Always need to boot with Single User Mode

Hi Community,
Since last few days, I am unable to boot my Macbook Pro normally, running latest version of OS X Yosemite. When I boot, it goes to grey screen with Apple logo and progress bar, once the progress completes to 100% (after 5-10 minutes which is very longer than usual), it asks me to 'Select language' which seems like fresh installation of OS X. In that case, when I click next and it doesn't detect my SSD (blank list of select installation disk/drive).
After reading some threads, I found work-around and always need to boot into Single user mode (by pressing Command+S during power on) and then need to run following commands...
/sbin/fsck -fy
/sbin/mount -uw /
"device is write protected" numerous times
reboot
and then only it loads OS X and displays login screen. This happens all the times and I need to follow above steps always to get login screen.
How can I fix this?

Please help me out here. I tried booting it off a USB flash drive with ATV flash but that gave me some errors and prompted me to login with username [email protected] with password frontrow
But I am not sure how to get to login using a suitable input. I tried to telnet it using my PC over network but I dont think it has initialized anything (like wifi or network) at the prompt. Would it take USB keyboard input? All I can do is remove the power and restart it with the usb flash out and get into then get into the recovery loop. I am not sure replacing the hard-drive would help. Any help would be greatly appreciated.
Thanks

Boot Snow Leopard from Thumb Drive in Single User Mode on Macbook Air

I'm trying to boot from a thumb drive that I transferred the Snow Leopard .dmg on. My macbook air only lets me get into single user mode. Every time I try to boot or enter safe mode or regular mode, the Macbook Air shuts down.

I do have the installation media on my usb flash drive. I'm sure it's leopard, and the problem is that I cannot get passed the apple logo on boot. The laptop turns off after trying to finish the boot for twenty seconds. However, I can get into single user mode. I just can't seem to install the media in single user mode due to my lack of know how.

Restore DB from backup with move - need to set to single user mode first and then reset to multiuser?

Im going to restore a recent backup from a production server DB to a test server DB and I want to do it through tsql. The DB already exists on the test server, I just want to overwrite it with a fresh copy. There may or may not be some activity
on the test server that is connected to the database, but its not important and can be abandoned/discarded.
This is what Im getting ready to do
First, get an idea of what the file paths are specified in the backup file
RESTORE FILELISTONLY FROM DISK = 'file_back_to_backup here .back .dat etc'
Then, set the DB to singleuser mode, and discard any connections/transactions currently started
ALTER DATABASE MyDBName
SET SINGLE_USER WITH
ROLLBACK IMMEDIATE
Then, do the restore, specifying the paths to the mdf/ldf files that already exist.
RESTORE DATABASE MyDBName
FROM DISK
WITH MOVE 'db logical name' TO 'new data path .mdf', MOVE 'log logical name' TO 'new log path.ldf';
Questions:
(1) If I specify the data and log file paths as ones that already exist, will they be overwritten? This is what I want, as I just want to copy the prod db over to the test server.
(2) Do I need to explicitly reset the DB back to multiuser mode, or does this happen after the restore?
(3) Anything missing from the above script(s) ? Suggestions?

(3) Anything missing from the above script(s) ? Suggestions?
1.Just restore the backup with REPLACE command and it will overwrite the current database.
2.No , database will be automatically put to Multi user mode if you are restoring with recovery
3. Single user script is fine .Change restore script like no need to use with move option
restore database db_name from disk='location' with replace
Please mark this reply as the answer or vote as helpful, as appropriate, to make it useful for other readers
I think I will still need WITH MOVE, as the files in the backup are using a different path than where they are located on the test server, correct?
RESTORE DATABASE MyDBName
FROM DISK
WITH MOVE 'db logical name' TO 'new data path .mdf', MOVE 'log logical name' TO 'new log path.ldf' WITH
REPLACE;

IMac G5 won't boot in normal and safe mode, but will from single-user mode

Hello everyone,
I'm quite new here, so I try to do my best if you have a question.
Yesterday, someone nearby me had a iMac G5 (Powermac8,1), and he sayd, that the computer sometimes will boot, sometimes not.
I did test it, I thought it was running fine, but when I played some music in iTunes, it was stuck on 9 seconds, and crashed (with a kernel panic). The guy also sayd, that there was nothing important on the computer, so a clean install was fine.
Now, the problem is, that it will not boot in normal mode (without anything pressed on boot), also it won't in safe mode (shift-boot), but it will, when I enter single-user mode, mount the hard drive and exit from single-user mode so it will go futher on booting. Sometimes it will not, and immediately gives you a kernel panic in single-user mode, but it will 90 percent of the time.
Then you've got another problem: when it's running in the normal desktop from single-user mode, it'll be stuck after some time again. If I look into the Kernel Panic file created, most times it's because of Spotlight indexing, so I disabled that.
He also gave me the disks (Apple Hardware Test and Extra Applications, and iMac G5 Mac OS X Install Disks 1-3) that came with the Mac. He sayd that I could use them, but I think he didn't test out the SuperDrive, because when I insert a disk, it will try to read, but it will make 2 same sounds, and quits after 10 tries, when it will spit the cd out. Also normal (audio) disks.
Also, I must hurry with the commands for mounting and exiting in single-user mode, or it will just not boot.
In all cases, after 30-45 seconds from pressing the power button, the fan will start blowing at full speed, and it will stop after the exit command in Single-user mode. That's weird.
I can't do anything with the SuperDrive, I can't normally boot in Mac OS X except for Single-user mode (but I don't think he would like to do that every time the computer boots up), and I have very limited time when Mac OS X arrived on the desktop.
When booting in Verbose mode, it will be stuck on this:
AppleSMU::PMU vers = 0x000d004c, SPU vers = 0x15, SDB vers = 0x01,
(and sometimes ends with a kernel crash by fsck_hfs)
Things I've tried (without any success):
- /sbin/fsck -fy (in single-user mode)
- Disabling Spotlight and mds
If you want some more information, feel free to ask!
Greetings
-MrYoranimo
PS: My main language is Dutch, so my English can be bad at some points.

Thank you for your support! This reply is a little bit late, because I was to the camping this weekend.
The only thing I sure do know, is that the iMac has a bad SuperDrive. That's one problem, but I don't really wanna use it, and you fix everything by Single-user mode and when I get to the desktop to test things and change stuff in the Preference Panes.
What also came to my mind was that there also is a problem with the videocard (driver), because sometimes when I boot into Single-user mode, I can see some white pixels which aren't supposed to be there. And when booting from SUM you can see that some of the colors are different and there are weird patterns on the screen.
I also tried to setup a NetBoot server on this computer (MacBook Mid 2010) with just Lion 10.7.4 on it, but I'm not that expert and I didn't really find the good posts on the Internet, although I tried it with the Server applications and both Server applications and DeployStudio. But I didn't succeed.
I don't really like buying a new FireWire hard disk or external FireWire dvd reader/writer, except if it has USB support, because my MacBook doesn't support FireWire, and I really wanna make use of it then.
If I know more or have fixed it, I will surely post again here with what I did to fix it (if no one else has posted here already ).

Internal HD on mac mini not well... need to boot in Single User Mode

Internal HD on mac mini not well... need to boot in Single User Mode.
I only have a Bluetooth Keyboard and Bluetooth Mouse so when I try to boot in Single User Mode (to do the /sbin/fsck hard drive fix thing) it doesn't see the Bluetooth Keyboard. What's the solution?
I also used SuperDuper to use as a boot drive but it won't unmount my internal HD. arghh..
Help

I have a corrupt drive and was unable to repair all the errors after booting from OS X installer disk and choosing Disk Utility...
I followed the "boot into single user mode" instructions hoping to complete my repair with fsck, however once I got to the localhost:/ root# prompt, my keyboard seemed to be unrecognized!
I tried 3 different USB keyboards - original Apple USB keyboard, Kensington Mac USB keyboard and an old SGI USB windows keyboard. All were able to enter the apple-S key to get into single user mode but NONE of them were able to type any commands whatsoever.....
I'm thinking my only option is to boot the mini as a target drive off my laptop and try to backup my 30GB of music and photos before wiping the drive...
2nd option might be to try Disk Warrior for $79??
Anyone else have ideas for me?

Won't boot normally or in recovery and single user mode, safe mode hangs up halfway

iMac locked up with visual glitches while playing the Mac beta client of League of Legends. Had to force a shutdown by holding the power button. Now it won't boot; after the Apple logo and spinning wheel I just get a white screen. I tried launching in recovery mode, that didn't work. Then I tried safe mode; the bar filled a little over half and then nothing but white screen. I was able to boot single user mode once; ran fsck -fy and rebooted, still white screen. Now I can't get back to single user mode. I booted with command option P R to reset the NVRAM and got the second chime, but still nothing.
Luckily all my important files are in the cloud, but I'm really hoping my computer isn't completely dead. I haven't had any issues in the past. I've even been playing LoL for over a month with no issues, until now when I tried to play the newer game types, Dominion and ARAM; both caused visual glitches forcing shutdowns. I was able to restart my computer with no problem after the first two visual glitches, but after the last one I am stuck at the white screen as I described above.
Thanks in advance for your help!

I'd bet the drive is damaged. You could try reformatting if possible. Again, you are booting from the Recovery-10.8.2 disk if you can. If you can't, then you will need to use the installer disc that came with the computer.
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Unable to boot from cdrom in single user mode

I have lost the root password for solaris 9.So, I tried booting the system with solaris 8 CD in single user mode(i.e, at ok prompt, boot cdrom -s)
But I get the following error.
rebooting with command :boot cdrom -s
boot device :/pci@1e,600000/ide@d/cdrom@0,0:f file and args -s
boot:cannot open kernel/sparcv9/unix
Enter filename:[kernel/sparcv9/unix]:
Please let me know why is this error?.Is it becos the CD is corrupted?

Also, the particular Solaris 8 you've chosen could be a distribution that's too old for your particular computer's design.
For example, a Sunfire V440 would need Solaris 8 HW 7/03 or newer.
http://sunsolve.sun.com/handbook_pub/Systems/SunFireV440/Sun FireV440.html
Solaris 8 HW 2/02 would not work.
What model system, and what version Solaris are you trying to use?

Command Line Expert Needed: Deleted hostconfig (+ others) - boots to single user mode only !

Mac OS X Tiger 10.4.11
Deleted folders/files when logged in as root user. (don't ask!)
On restart , wont boot up , get grey screen with white apple logo the black screen with command line: localhost:/ root#
Started up from install cd - repaired permissions (ran twice) & verified hard drive . All okay.
Restarted but still goes back into command line with same localhost:/ root prompt
Tried a bunch of different things as per advice on these boards - discovered that there is no hostconfig file.
Restarted into verbose mode.
Here are the lines that i think may reveal exactly what I messed up - and hopefully someone out there has an idea how I can try to fix without having to do an archive/install.
BSM auditing present
disabled
rooting via boot-uuid from /chosen: (here a very long string of numbers and letters looks like a password)
Then a long line about
"got boot device = IOService:/MacRISC2PE ........."
Then, the following
"BSD root: disk0s3, major 14, minor 2"
"CSRHIDTransitionDriver::stop"
"IOBluetoothHCIController::start Idle Time Stopped"
(AND HERE'S THE BIGGIE:)
/etc/rc: line 93: /etc/hostconfig: No such file or directory
Apr 1. 06:01:44 launched: /bin/sh on /etc/rc terminated abnormally, going into single user mode
localhost:/ root#
I'm pretty sure I messed thing up pretty well - was mainly network/server folders and files - definitely samba, which I think I deleted, and under "network" in the finder, I also might have deleted my computer from the server list
As an aside in case this provides any insight, when I go to the terminal app when starting up from install cd, the prompt reads :
"bash-2.05b"
I'm also able to see the contents of my hard drive when using disk utility from install cd and and trying to "mount image" ---
Everything looks intact in terms of folders/files in my user account, but in the /root folder, there's only /library - which is empty.
Any help, insight, troubleshooting and even scolding - will be welcome! I need this thing booted
Cheers

I do not have a backup. Should I back up before I try doing a reinstall of the os x?
That's also known as shutting the barn door after the horse has bolted.
It can't hurt, but it's not going to help much.
Camelot: when you say "apps and user content should stay intact" - doesn't sound very definitive. Are there any variables that come into play?
No.. generally it's pretty reliable, but yours is an odd situation. I wouldn't expect to lose any user data, just CYA
I do have a start up disk along with some apps that I created in retrospect many years ago ....(I think it's os x 10.2.8) Can I use this to boot up and then just navigate to my user files so I can get some things done that I need to?
Unlikely. For one have you even tried restoring from your Retrospect backup? (it's not the most reliable system).
Secondly, you can't boot from your Retrospect backup, so you'll need to restore that system to boot from it. Have you got a second disk to restore to (you do NOT want to restore 10.2.x over your 10.4.x system).
in terms of "random deleted files" : not entirely random
Ok, maybe not entire random, but it's also somewhat unknown. You need to have some idea of what files you're trying to restore, but if you haven't got them in a backup where are you going to get them from?
You cannot just take old copies from your 10.2.x system and hope they'll work (in case that's what you're thinking).
The BEST solution is to boot from the 10.4.x installer disk and let it do its thing.
And for what its worth, Unauthorized access attempts, in and of themselves, are not a cause for concern since they were clearly caught by the OS. It's the access attempts that succeed (and are not logged) which are more of an issue.

Mac not booting normally after running '/sbin/fsck -fy' in Single user mode

HI, I tried to log in to single user mode and run the '/sbin/fsck -fy' command. This command failed. So I rebooted my Macbook pro by 'reboot' command. On bootup I hear the chime shoud and can see the Mac Symbol but never reach the login prompt. The round circle keeps rotating over the gray screen and nothing happens.
Then I again hard rebooted mac book and entered single user mode. I ran again '/sbin/fsck -fy' many times and after many attempts the command stuck and never returned.
Then I tried using the recovery method to reinstall MAC OS X. It asked me to choose the Harddrive where to install MAC OSX. But the option of "macintosh HD" was disabled and message was " hard drive locked".
Please help me how to boot my MAC normally :'(

Welcome to the Apple Support Communities
Boot in Recovery again and open Disk Utility. Then, choose "Macintosh HD" in the sidebar and repair the hard drive. If it is repaired, restart and OS X should start correctly. If not, you will probably have to format the hard disk.
You only have to use that command when you have problems with the Mac OS X volume filesystem that they couldn't be repaired with Disk Utility, and as this command got stuck, probably damaged the OS X volume filesystem

Help needed: Lion boots only in single user mode after a kasperksy unsuccefull installation

Hello everyboby,
I used to be a Sun Solaris sysadmin with root privileges, but I can't fix the Macbook of my girlfriend...
WHAT I WISHED:
I wished I could restore the boot INI/config files of a MacBook (the old one, made of white plastic, not the pro, made of "steel"), so that Lion started at boot, like it used to do, before a "fatal" kasperky installation.
WHAT HAPPENS:
the macbook plays the chord, shows the Apple logo, seems to load the OS (Lion) and then switches to graphic mode, BUT the desktop (is "desktop" the name of the screen of the operating system, once it's fully started, like on a PC?) doesn't appear, only a grey screen, then nothing happens.
I guess that probably Lion is fully running under the grey screen, but without the screen/video been correctly setup, I cannot interact with the notebook.
I CAN boot in single user mode, mount the file system in writing mode and read and write the disk.
WHAT HAPPENED:
my girlfriend upgraded to Lion from Snow Leopard and used the notebook for a while (one month?), then she decided to upgrade kaspersky, but the installation failed somehow and now the notebook is stuck.
WHAT I TRIED TO DO:
- I read this: http://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPSystem Startup/Chapters/CustomLogin.html#//apple_ref/doc/uid/10000172i-SW10-BAJCGEGG
- and that: http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/ man5/launchd.conf.5.html#//apple_ref/doc/man/5/launchd.conf
- and removed from the disk all the folders and files dealing with startup items AND kaspersky, but nothing changed: at boot the grey screen appears and Lion's interface is not loaded (or if it is, it's not shown).
- then I looked for some logs, found the kernel's one and found something that looks like an error message dealing with video inizialization... So, it really seems something is not working at video level.
WHAT I AM ASKING YOU:
some help, please... : is there anybody that can give me some specific advice on how the boot is done on a macbook with Lion? Are there some INI files I can copy into the macbook, so that it starts in grphic mode?
whatever...
thank you in advance!

IMac 7,1 boot only in single user mode

Hi all
I've a colleague with the following problem... his iMac 20'' (iMac7,1) is able to boot ONLY in safe/single user mode (with shift key pressed during boot).
If he tries to boot normally, after the usual Apple logo screen he gets a blank (light grey) screen. No finder, no login screen.
We've tried this procedures:
- SMB reset
- PRAM cleared
- OS Reinstall (we've tried from Lion to Mavericks... actually there's 10.7.5 installed)... note that ALL installation procedure has completed successfully.
- tested the 1 RAM module installed (seems to be OK)
- tested the HD (no problems found)
Despite all these attempts, this iMac is booting well only if we press SHIFT during startup. All programs run well, wifi is working and online update too. If we reboot leaving it to restart normally (no key pressed) it shows Apple Logo for 1 minutes, then (after a black reset of the screen) seems to crash/stuck into an empty grey screen.
Is possible to identify which driver/kext is causing this problem? It can be an hardware problem? How we can fix it?
Thank you!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Network / external access when booted in single-user mode from install CD?

So I have this iBook with a semi-functional hard drive: can't boot from it (either normal or single-user), can't use it in Firewire Target Disk mode, can't fix it with Disk Utility, an overnight run with Disk Warrior seemed to be hung, etc, BUT if I boot in single-user mode from the install CD I can then mount it readonly and see at least many of the files on it.
So now I want to slurp the important ones of those files off of it over the network (or in any other clever way anyone can suggest). I'm not a huge Unix or Darwin expert, so an exact set of commands would be appreciated. *8) A friend suggested to me that I might be able to 'init' it at a 'runlevel' that included the networking stack, but I dunno what that means. *8) Does the CD in fact include a full networking stack? Or anything else that I might be able to use to slurp some data from the hard disk before it gives up entirely?

I think Ronda was hoping you had the Tiger Instal DVD, which has a copy of Terminal on it.
You said earlier that trying to boot into Target Disk Mode didn't work. Would it help you if you could? If so, I can show you how to do it from Single User Mode. I've done it, and it works, although admittedly I did boot into SU mode from my HD, not my Instal Disc (I have tried that, it also works, I just haven't done both together).
If you can make use of this, post back and tell me what you get from which nvram when you are booted in SU mode from your CD. It's possible that command won't be available on the CD—so we need to check first. If it says "which: no such command", try ls -l /usr/sbin/nvram instead.

Booting in Single User Mode

Hello All,
Just want to prepare ahead of time for possible server-down cases where a drive fails etc. What I want to do is find out a bit more about how the boot sequence is completed.
If for example the primary boot partition was to become corrupted, is there an easy way to boot from the cdrom and enter single-user mode? From there I could mount a drive, bring up the nic, and transfer files etc, as needed.
Normally with the bootprom on Sun hardware the stop-a then boot -s cdrom would work. What's the comparable command for Solaris 8 x86?
Thanks,
Mike
