Thinkpad user mode drivers libraries

Hello,
is it possible to get documented assemblies/libraries containing Thinkpad user mode drivers for Windows? For example the Driver.Umdf.* libraries which uses the Setting app.
Thank you.

Using that option the kernel compiles smoothly. The problem here, is that I am not getting the kernel that I want. I am just building a normal kernel.
Any suggestion, let me know
Luis.

How do i repair my hard drive in single user mode when disk is full?

Hi there Apple Community!
I have an old Macbook Pro 17" with an upgraded 500GB harddrive and 4GB memory. I'm running Mac OSX Lion.
Was hoping you could help me out. THis is the situation:
Long story short I spilt wine on my macbook and the screen went a bit blobby. Switched it off for a few days, removed the battery etc. etc. Opened it up cleaned out as much of the wine as possible, but unfortunately some of it came in behind the LCD, so now the screen has a nice red stain. Obviously I'm not going to try to clean that out of the LCD.
My Macbook Pro still worked for a few days after that, but then my harddrive gave up. I booted in the Recovery HD menu, verified the drive and I got the error "Keys out of order - This disk needs to be repaired, click Repair Disk." I attempted to repair the disk but got the error "Keys out of order - Disk Full Error - The volume could not be repaired".
Unfortnately of this 500GB I only have about 7GB free on it, as I have a huge iPhoto and iTunes library. I did make a TIme Machine backup of my user directory, but not the system files. I don't really want to do a clean install because:
1) I'm paranoid that there's something I did not fully back up
2) I don't want to have to download the whole Mac OSX Lion again. I should have made a USB bootable backup when I had the chance. I don't have access to a broadband connection.
What I feel are my viable options, are as follows:
1) I did buy a replacement internal 500GB harddrive, so I can probably try to make an image of the hard drive to this new drive, but not sure how. I believe it's through the Disk Utility with the "New Image" option but not sure how to go from there.
2) Start up in Single User Mode and delete some unnecessary files and re-attempt to run the fschk -fy utility again (I tried this earlier and got the same Disk Full Error). - the problem with this is, I'm not familiar with the command line and have no clue how to delete files. I don't know my way around Unix.
3) I can also probably attempt to make a Ghost Image or Acronis Image of the failed drive to this new drive, but not sure if Norton Ghost or Acronis True Image will be able to read this HFS drive - I believe it's possible as it's a simple hard drive clone.
If you can guide me in the best option - probably there is a better solution than my proposed ones above, I appreciate any feedback and comments you might have!

hi Baltwo,
So I ended up copying my user folder to another harddrive. I managed to download the whole osx lion again, reinstalled, and recovered my home folder using this discussion:
http://support.apple.com/kb/HT1428
I have managed to get all my files back. My iTunes library works fine, but my iPhoto library when I open it, get the following error:
iPhoto cannot be opened because of a problem.
Here's the error log

I've done an Apple Software Update but it didn't find an update for iPhoto.
One thing to note is, this library was originally created on iLife 08, upgraded to '09 and it stayed on that version. It hasn't een upgraded to iLife '11. It worked fine on my previous install of OSX Lion. How do I recover the library without upgrading to '11 ?

Getting a "key" prompt when booting up in single user mode!!

I bought my used macbook pro about a week ago without the original cd's and manuals. I installed the boot camp package but rebooted without creating the drivers disk to do this later. When my macbook boots up now it passes the apple icon with the twirling round arrow, then it stays at the Mac OS X box forever. How do I fix this without the tiger CD.
I have tried booting up in single user mode and it takes me to a "key" prompt. Anything i type does not come up. I read the troubleshooting and it sayd that it should through me to a # sign instead so i can perform a "fsck --y" funtion.
Please help restore my Macbook!!

I waited 15min at the key prompt when booting in single user mode and it unlocked the command prompt.
I guess it's some sort of security feature for the root.

Freeze in Single User mode

Hi, my iMac G5 is freezing right away when I boot in single user mode. I mean right away at the prompt. I cannot even start typing anything. The fan start at 100% and I have to hard shutdown the machine. This happens ALL the time I boot in single user mode. EVERY TIME no exceptions.
I am trying to run a memory test (using MEMTEST) to see if my 1gig memory is defective. My iMac freeze randomly without me able to find a consistent pattern.
Questions:
1- Does the freeze at boot could be a problem with me using a bluetooth keyboard and mouse?
2 - If not, the fact of freezing at boot in Single User mode a possible explanation of memory problem (does the single user mode lock-up memory that could be bad?) as my iMac do not freeze (for a while) when booted in multi-user mode.
My setup: 2 ghtz iMac G5, 1x1gig Kingston PC3200 memory (sold and installed by my Apple reseller). My G5 is 7 month old still under warranty.
I am new to the Mac - I switched from PCs.
Thanks for the help.
iMac G5 + Thinkpad T40 Mac OS X (10.4.2)

With the PC-Viewsonic keyboard, Pierre, the symptoms you describe are exactly what you would expect.
Third party, non Apple, keyboards, even wired ones, can't usually be used to do anything beyond simply starting up in SU mode (you can start them up and get to the prompt, but when you are there you can't do anything further).
The same applies to Apple Wireless keyboards when running versions of the OS 10.4.2 or earlier, or if the bluetooth firmware isn't up to date. Again, you CAN start them up in SU mode, but you can't do anything with them after you reach the prompt.
As far as the BT issue goes, as you say its running 10.4.6 I'm beginning to wonder if there was a problem with one of your OS updates. I'd be inclined to download a fresh copy of the full 10.4.6 Combo updater, and run it again. Probably worth running the Blue Tooth firmware update again, too, just in case.

Network driver attachment booting cdrom single user mode

I am attempting to boot from cdrom in single user mode and reach some network shares. However, when I boot cdrom, the server does not attach the network drivers, meaning I cannot plumb up any of my interfaces.
Now, I should add that we have an XVR-300 card in an XAUI PCI-E slot. I read somewhere that this can disable one of your network ports, but shouldn't it still see the other ports and attach the network drivers?
Any body have any ideas or anything I could try?
Thanks!

User Mode Linux -- Compiling problem

Hi,
I want to run the user mode linux for linux-2.6.17.6. When I try to compile the user mode linux I get this error:

I was looking up a lot of time in google.
My steps to compile it is:
export ARCH=um
make defconfig
make
If you have any suggestion, let me know.

Single User Mode Crash HELPPPP!!!

So, I just finished installing windows 7 build 7022, and using the modified bootcamp.msi to get all of the drivers installed.
I went to boot into OSX, and all that it does is sit on the grey apple screen while the gear spins, and spins, and spins.
I went into single user mode and this is the crash report that I got.

1. what does AFAIK mean?
As Far As I Know
2. What I have gathered is that it is near next to y difficult to repair permission fro the CLI and single user mode.
Correct. You can't use diskutil because the disk framework isn't loaded. You can do it if you're booted from an install DVD, though.

Data back up from Single User Mode

Hello,
I have a problem with my 700 MHz iBook, dual USB, with OS X 10.3.9.
Unfortunately the OS doesn't start up because of "overlapped extent allocation" problem...
I would like to re-install the complete OS but before doing it, I would like to back up some directories.
Is it possible to save some data, by connecting an Ipod or some sort of external peripheral, from the Single User mode?
If yes, how can I do it?
Thank you in advance from your kind support.

Before giving up the ghost check out these:
http://docs.info.apple.com/article.html?artnum=25770.
Manually fix Overlapped Extent Allocation Errors without Disk Warrior
Overlapped overlapped extent allocation errors can be the bane of any Mac user's existence. Often, these errors go unnoticed until the problem becomes visible: your Mac might refuse to boot, crash unexpected, or worse, critical data might disappear from the Finder. Disk Utility can detect, but not fix overlapped extent allocation errors, and certain third-party utilities, such as Alsoft Diskwarrior, can fix them, but generally without reporting the consequences.
Overlapped extent allocation error occur when the file system thinks that two files are occupying the same area on the hard disk, hence overlapping on the same "inode," which is the structure which holds the location of the data blocks the file occupies, and also file permissions and flags.
Clearing the "overlapped" or "overallocated" extent allocation essentially means that you'll have to lose some data, because the only way to remove the overlap is to delete the file that's occupying the inode. So, if you suspect, or find out, that the guilty file is a critical system file that resides in one of the hidden system directories such as /etc /var /usr/ or visible system directories such as /System or /Library, and you don't want to reinstall the whole OS (which might not fix the overlapped extent allocation anyway), it's good to have another disk available to copy the files back to your original disk if necessary: a second bootable hard drive or a firewire drive connected to your Mac when you remove the misbehaving file. Just make sure that when you copy the file back to your boot disk that the permissions are correct, so it's best to use the "ditto" command, so that all sticky bits, flags, and permissions are preserved.
In case you didn't know, you don't have to boot from an install CD in order to check for overlapped extent allocations. All you need to do is restart your Mac, while holding down command + S to boot in "single-user mode."
At the command prompt that appears, type:
$ fsck -fy
If you have an overlapped extent allocation, you'll see:
"Overlapped Extent Allocation" (File 123456d)
No matter how many times you run fsck -fy, you'll never be rid of the error.
So, simply issue the following command:
find / -inum 123456 -print
Note the "d" was dropped, or any extra letter that appears after the inode number.
The find will return a file name that matches with the inode number, and the path to that file. If you remove the file then the fsck will not return this error next time you run it.
However, before you can delete the file(s) in single-user mode, you'll need to mount the file system. Type:
$ mount -uw /
When done, issue the "sync" command, and that will flush the write cache so that all pending writes are written from memory to the disk. Also, since most OS X 10.3 Macs use the HFS+ Journaled file system, it might be a good idea to disable the journal before booting into single-user mode by typing:
$ sudo diskutil disableJournal /
then re-enable it when done fixing the overlapped extents and rebooting normally:
$ sudo diskutil enableJournal /
Chris Anderson is a long-time Linux propellerhead who just got his first Mac, an ibook G4, and can't keep his hands off of it. He currently works as a "The Architect" and general visionary for a maker of world-class collectibles.
If you own Disk Warrior then it should be able to repair a drive with overlapped extents.
There are two backup utilities included in Unix - psync and rsync. You will find them in the /usr/bin/ directory. For documentation simply enter: man psync or man rsync. In order to write data while in single-user mode you need to issue the command: /sbin/mount/ -uw / (Note: there is a "space" between the "uw" and the "/".) To mount an external drive you will need to provide the mountpoint for it in place of the "/", e.g., "/Volumes/volname") without the quotes.

Kernel panic on MacPro in Single-User mode after memtest.

I've had about 7 kernel panics in about 7 days on a new MacPro. 2 gigs of RAM (Apple Installed). Fresh install of OSX (no user import). While going through the troubleshooting process I ran memtest in single user mode. Ran it all night no errors.
So in the morning I typed ctrl-c and then exit (i think)... it seemed to start the process of booting and I got another kernal panic. I've actually done this three times now.
I checked panic.log and all the error messages but 1 were the same. Including the ones I got in single-user mode (copied below).
Should I be able to gracefully exit out of single-user mode without a kernel panic?
Does this point to a RAM error even though memtest and AHD for that matter ran all night without finding anything?
I'm all set to try again (taking careful notes this time) to see if I can reproduce but I was hoping for some feedback first.
Thanks,
Craig

Welcome to Apple Discussions!
Yes, your memory or memory slot, or memory seating is bad or off. "Uncorrectable Fbd memory error detected. ferr = 20000000 , nerr == 00000000, fErrFat = 20000000 nErrFat == 00000000"
Clearly a memory related issue. It may also be that memtest doesn't know how to diagnose the new kind of memory and is reporting that back to the logs. Take it in to a service center to have all the boards replaced to make sure the issue isn't reproduceable with new memory. If it is, then I'd consider the slots on the logicboard a problem.

Can't log in with valid password, can't boot from disk, can't access disk utility, in single user mode can't reset password as appears locked in caps mode with '?' for forward slash, can anyone help?

Can't log in with valid password, can't boot from disk, can't access disk utility, in single user mode can't reset password as appears locked in caps mode with '?' for forward slash, can anyone help?

Which keyboard layout you were using? German, French ... I suppose your layout is reset to the default: US and you are unable to find the "?" or "/" ...
Please have a look into the keyboard viewer, to see how the layout of your keyboard is actually.

I changed my wheel group properties to no access at top disk level. I messed up, how can I change back in single user mode "command s" as I am now in Thailand and not able to access startup disks?

I messed up, I changed my "Wheel group" properties to No Access ( or something other than the default) at the top level of my startup disk "Macintosh HD".   Now my computer won't start up, I just get the spinning wheel of death.    I also am in Thailand right now, so I cannot go to a Genius at an apple store, nor do I have startup disks available.
So I was hoping there was a way to change back the properties of my disk (Volume) in single user mode (via Command +s) during startup, i.e. can I do a chmod command on the Macintosh HD listing under the Volume Directory.    Or where do i fix this?   Is it fixable without startup disks, etc...
THANKS FOR ANY HELP!!!!
If you could also please let me know you have an answer, I WOULD REALLY APPRECIATE IT!!!
thanks so much

Thomas,
Thanks for the info on command-R, didn't know about that!!!
Yes I changed the sharing "Wheel Group" permissions on my hard drive via Get Info.    But that's all I did.    And then most of the apps wouldn't respond with anything.    So not knowing I did something stupid, I decided to re-boot, and then nothing but the Wheel of Death at startup.
I was trying to limit access to my computer on this network, changed my public folder settings, and then I thought why not the whole hard drive, but at that time I had no idea what the "Wheel Group" was... so I shouldn't have touched it, BUT IT DID ...... argggggg....
I managed to go to an internet cafe & research the problem yesterday.    I used the command +s single mode to get in, and then did the necessary steps to mount the drive so I could make changes.   I basically did this:
Boot into single-user mode (boot while holding down CMD-S)
Follow the on-screen instructions to mount the file system as read-write (a fsck command followed by a mount command)
Type the following: "chmod o+r /" followed by "chmod o+x /"
Type "exit" to leave single user mode and complete the boot sequence.
I found it at this link http://forums.macrumors.com/showthread.php?t=416180
It worked... thank God!!!   Well so far so good.
I was going to try my own fix by chmod on the Hard drive listed under Volumes directory, but that doesn't seem to match the info under Get Info Window.    So I just used the fix above.    I probably should now go and do "Disk Utility - repair permissions", however I am a little gun shy right now, so I will probably wait until I am back in the States so I can go to an Apple store if it messes up.   Right now I'm following the "if it ain't broke, don't fix it" MOTTO...
So Thomas I just wanted to say THANKS for replying so quickly, and I really appreciate your help!!!
(yes I know I shouldn't have used my email addresses, but I WAS DESPERATE, but that's still no excuse)
Hopefully maybe this thread will help someone else out in the future....
Okay, thanks again!

Why can't I enter single user mode on my Mac Mini for an admin password reset?

Hi,
I recently created a new user account for my mac and deleted the old one, not realising that this was the only account with admin priveleges. As such, I no longer have access to administrator priveleges, and cannot grant them to my new user account.
I have tried to boot in single user mode and recovery mode but neither command results in any reaction on the part of my computer.
This thread follows on from a previous, unrelated disscussion:
BDAqua: If you hold alt key at bootup do you see a lock in the middle?
Yenots: No...what does this mean?
BDAqua: If it did, it would mean Firmware Password Protection was enabled, which prevents booting in other modes, so that's not the problem, are you using a wired Mac KB, or Windows KB?
Yenots: I'm using an 'Apple Keyboard with Numeric Keypad' [ http://store.apple.com/uk/product/MB110B/B/apple-keyboard-with-numeric-keypad-br itish ]
If you find me here BDAqua, hit me with your knowledge!
Any other contributions are welcome and, now we're under the right heading, will hopefully help other users who have encountered this problem.
Thanks, Cristo

Hi,
Thanks for the link to MacPilot, and the sexy screenshot. I found an archived version for 10.4 on the koingosw website. That solves getting into single user/safe mode. Though I'd be interested to see whether sudo nvram boot-args="-s" will result in single user boot.
As for creating administrator priveleges for my new user account, I've found a method which looks good:
     \single user mode\
     cmd-s
     \mount drive\
     mount -uw
     \open 'directory access'\
     lauchctl load /System/Library/LaunchDaemons/com.apple.opendirectory.plist
     \list users\
     ls /Users
     \change password\
     dscl . passwd /Users/<username> <password>
I think that this method intends that if I change the root users password I'll be changing the administrator password (as root is the only user with administrator priveleges), and subsequently be able to change my new user accounts priveleges using 'netinfomanager'. But I'm not 100%. Could you give me your opinion on this?
Furthermore, three keys 'L' 'O' and '(' aren't working on my keyboard, which means I can't try this until I find an intact keyboard to borrow. I was thinking maybe a mod version of the above instructions would work in terminal using sudo, so I could use the keyboard viewer to type the missing characters. If you have any ideas on constructing such a mod I would be interested to hear them.
Otherwise, Thank You for your help BDAqua! And enjoy your summer wherever you are.

Single User Mode : Read Only Filesystem

I can't edit files in single user mode as Root. When I try to edit them I get a msg saying "Read Only Filesystem".
I have tried chmod with no evial. I want to change my .profile as root so cls='clear'.
Any ideas?
Also when I try to login to my account in single user mode it says that account does not exist. However I'm in that accunt right now!
Thank You.

When you boot up into single user mode, there is a single recognized user -- root. That's why they call it single-user mode and not multi-user mode.
When you boot up into single user mode, the disk mounts as read-only. You have to make it writeable in order to do anything to it. I forget the actual command but it displays on the monitor nearby where it gives the "fsck" command syntax when you first boot into it. It's something like "mount -uw /" or something to that effect. It is saying to mount the root drive ("/") with user write privileges.
Then just "pico /Users/Mephux/.profile" (although I profess that I don't understand why you have to edit this file as root).

Wipe a HD via Unix in Single User Mode?

Is it possible to wipe a hard drive using diskutil or another method when booting up in Single User Mode? We routinely need to wipe drives and if possible, this would be the easiest.
I suspect because the OS that boots in Single User Mode is on that same drive will make this impossible.
Thanks in advance for your tips and comments,
Doug

Yes, you cannot erase an OS while it's 'hosting' the erasure. Single user mode is part of Mac OS X, so it's on the hard drive, not in the firmware or anything super-low-level like that. Oh well. So... you might be able to erase the vast majority of user, application, and even OS files, but it won't be complete and won't be 'as good as' a volume-format.
A couple alternatives come to mind (sorry if you know all this. Not trying to be pedantic or patronizing, just making sure you know your options).
We keep host computers around just for running wipes, backups, and diagnostics that cannot run from a drive holding the booted OS. You simply restart the to-be-wiped Mac holding the 't' key, connect it via firewire, and treat it as an external hard drive.
You could also just boot from a Mac OS X install disc and wipe from the copy of Disk Utility included on the disc. Better yet, throw a +bona fide+ copy of OS X onto a pocket hard drive, boot the victim-Mac from that (hold option while it is first starting up), and wipe the internal HD normally, now that it's not in use. You could maybe even use single user mode in the booting OS, like you'd imagined, and format from there (I'm not sure that would be faster than letting it boot normally, though, as you might have to use "dd" or some other similar low-level wipe method, as I don't think the frameworks required for Apple's cli "diskutil" are available in single user mode).
I haven't tried to use it on a Mac, but I have a 256 MB USB flash drive with, er, ['Darn' Small Linux|http://tinyurl.com/5md7t] on it for diagnosing Windows boxes. It runs a script on boot which, if you don't intervene to run utilities or what-have-you, will wipe all attached hard drives and shut down. I keep it locked up for understandable reasons, but its super useful just as a time-saver, booting most machines and beginning the countdown-to-wipe in under ten seconds.
Anyway, let us know what your goals and thoughts are.
Cheers, Joel

Single-User Mode Copying Files/System Does not Boot Past Apple Logo Screen

I have a Macbook 2.0GHZ, 2GB RAM, that recently tried to download a secuirty and keynot update. Following the download the system will no longer boot past the Apple Logo Screen with the spinning wheel. I do not have access to a OS disk yet or to a firewire cable either. I've have seen posts from others that describe how to use traget disk mode to reinstall the secuirty update manually and then they can boot their computer. Safe mode will not work. I did boot into single-user mode and run the disk utility there and it says my HD is OK. Since I do not have a firewire or an OS Disk, I am wondering if there is a way to copy those files i need to a USB pen stick then install them onto the computer via single-user mode, considering this is the only way I can boot and manipulate the machine at this time. If this is not possible please let me know so I can find a way to scrounge up a firewire cable or disk. Thank you in advance for any assistance.

Thanks to Limnos and BDAqua I know you guys have helped others with these kind of problems from the other posts I read. I just want to list what I did exactly in case anyone wants to try to do this with a usb drive or does not have access to a boot disk or firewire cable.
1: Install security update on a pen drive
2: Boot in single user mode, CMD-S on startup
3: /sbin/mount -uw /
4: mkdir /Volumes/usb (usb can be any name, name of usb drive or anything you want)
5: ls /dev (you need to get the drive listing for the usb drive to mount it appropriately, it should be disk#s# but this is close to what the HD and Cd drives are listed as so you may need to list once before you put the usb stick in and once ater. I had issues inserting the usb drive in single-user mode and it would freeze up the root drive)
6: /sbin/mount_msdos /dev/disk1s1 /Volumes/usb (this mounts the usb drive, i had to use msdos because of how my usb drive was formatted, you may need to check your usb drive format, hfs is the apple format for usb drives but it did not work for me)
7: cp /Volumes/usb/SecUpd2009-001Intel.dmg (this copies the files from the usb drive to the root drivel, at this point you no longer need the usb drive)
8: hdiutil mount /SecUpd2009-001Intel.dmg (this mounts the disk image)
9: cd /Volumes/"Security Update 2009-001" (after i mounted the image this is how it appeared in the Volumes directory, you might need to do ls /Volumes to get the name, the quotes are important to get the whole file directory changed)
10: installer -pkg SecUpd2009-001Intel.pkg -target / (this installs the acutal update, i used the SecUpd2009-001Intel.pkg and it worked though I think you might be able to use "Security Update 2009-001" with quotes as well.)
11: reboot
i hope this helps anyone looking to do this. Thanks again to those who helpes and all the other posts that had information that helped me identify and then fix my issue! I still love my mac.
