Powerbook G3 (Bronze) Won't Boot! Exec Fromat Error

Recently, I started a software update from Apple. During the update, my PBG3 froze. After a hard boot, I get these three line that keeps repeating.
(Current Date and Time) init: can't exec/bin/sh for single user: Exec format error
(Current Date and Time) init: can't exec/bin/sh for single user: Exec format error
(Current Date and Time) init: can't exec/bin/sh for /etc/rc: Exec format error
This keeps happening. I have reset Pram, PMU, etc. I have had this machine for over 8 years and I have upgraded RAM and the Hard Drive. I fear that I have tried for one too many updates. Please Help!

Maybe I should elaborate. I am using a PowerBook G3 Bronze keyboard, running 10.2 (Was at 10.3.9)
A few weeks ago I was online (wirelessly through Verizon DSL) and everything froze. Tried to restart over and over and kept getting Darwin. Reinstalled the system software (back to 10.2) from original disks. Same problem. Now when I turn on the machine I get the MAC OSX start up screen where I log in. I hit log-in and type in my password from the pop up and then it goes to the Darwin/BSD screen. So, after looking though the help and threads I have come to this point of starting up in single user mode and this is what happens:
@ the sh-2.05a# I typed in /sbin/fsck -y (then here is the rest as it shows on screen)

That's it. Then it sits there. Sounds like it's working for a while then like goes to sleep. This is the 2nd time I have done it. The first time I let it sit for like 1 hour and a half. Then I shut it off with the power button and restarted it, got the same results and so I started it in single user mode and tried this again. The only thing that changed from the first time to the second was the volume free block count the first time it said "(It should be 1844564 instead of 1786963) It is currently 12:59 and it has been since 12:06 when it said "Repairing volume." Can't hear anything. Can someone please take pity on me and let me know what I should do before I ruin this thing? I have been the only owner of this thing and have never had a history of problems. (Except for battery drainage, but now I use the adapter)
One other thing: When I get to the Darwin screen and it asks for my login and then password, I haven't got that right either. It says
Darwin/BSD (G3computer.local.) (console)
login:
haven't a clue what they want. Tried a bunch of things, but with no success.

  • Powerbook 12 inch won't boot and I need to create a startup CD/DVD

    My son's PB 12" won't boot up. We are on vacation and I have my 13 macbook with me, but none of the support disks.. I am wondering if there is a way to create a boot CD/DVD from mine to use with his, to hopefully get his computer working again. Any help would be great!

    Hi, Ross. No, there isn't. The OS that runs your Intel-based MacBook won't run at all on the PPC-based Powerbook.
    Hold down the Command and S keys on the Powerbook while turning it on, and use fsck in Single-User Mode to attempt file system repairs, as described in this article.

  • Powerbook g3 Pismo won't boot

    Hi guys i just got myself a pismo (always wanted one) but it won't boot at all !!
    I get power to the battery the keyboard and the HD spins but thats it, no chime and nothing on screen !! also the power light does not light ...
    Can anyone shed any light on what the problem may be

    A dead PRAM battery can cause this. So disconnect the battery connector (it's under the kbd). This site has instructions. http://www.ifixit.com/Device/PowerBook_G3_Pismo If you get it booted, reconnect the battery. It's a rechargable battery so it may take a charge.
    You can also try pressing the reset button on the back panel neat the tel line connector.

  • Wiping Hard Drive on PowerBook 1400 that won't boot from CD

    A colleague has a PowerBook 1400 and would like to erase the hard disk drive. The problem is that I can't get another drive attached to the machine, Startup Disk crashes whenever I try to start it, and command-alt-shift-delete doesn't enable booting from the CD (the 1400 doesn't work with the C key on startup).
    So, I can't get it to boot from the original media (which has OS 8.6, I think); I also tried booting from DBAN, but that didn't work.
    I also can't get the installer on the original media to run. So I tried to create the Disk Tools disks using the original (CD) media, copying the folder to the desktop and then removing the CD and putting in the floppy drive, thinking that Disk Tools might very well have a formatting tool, but that failed, claiming that the image for Disk 1 is bad (I imagine it's not the image, but a problem with the computer).
    We're not interested in getting the computer running, really (though it runs ok), just in wiping the HD. Any suggestions? Are the Disk Tool images something that Disk Utility on an OS X machine will recognize as a floppy disk image?

    Well, I thought that wouldn't work. Guess what? It did. After zapping the PRAM, had no trouble booting into the CD. However, the disk tools didn't seem to include a secure wipe tool, so I finally ended up removing the hard drive and plugging that into my MacBook with a 2.5 in. USB enclosure and using Disk Utility to do a secure wipe, then putting the drive back in the machine and reinstalling OS 8.6.
    In case anyone else is looking for a solution to this problem, to remove the drive: unplug the laptop, remove the battery, unscrew the three phillips screws on the edge of the battery slot, then the screw nearest the PCMCIA card slot, then remove the speaker grill, slide out the keyboard, unscrew the two screws at the top of the hard disk drive tray, separate the case slightly from the left front corner just enough to slip the hard drive ribbon out from underneath the top of the case, unplug the drive, then unscrew it from the drive tray.
    Thank you all for your help.

  • Powerbook G4 17" won't boot...failed drive or logic board??? HELP!!!!

    I am in need of some assistance. My Powerbook no longer works although it chimes when powered up. I have reformatted the hardrive and reinstalled a new operating but still there is no booting up.
    **The question that I pose is: hardrive failure or logic board failure.**
    I have tried to the Command-Option O+F, I have tried holding down the Option key (which starts the machine sporadically), I have tried the Shift key and also the DVD...nada squada on all of these.
    Please help.

    Have you inserted the first OS X DVD and rebooted holding the C key down? This would boot from the DVD. Are you able to do that?
    Have you run the Apple hardware test? With the OS X DVD that says 'AHT Version x.x' in small print, insert it, and reboot holding the option key down. Choose the Apple hardware test, click on the arrow pointing to the right, and follow directions. Choose the extended test. Does that tell you anything?

  • Powerbook G4 15" won't boot ... sometimes

    Hi,
    My daughters friend needed to upgrade the hard drive on his 15" Powerbook G4. We installed a new WD WD2500BEVSRTL drive, and installed Leopard from scratch. All worked great until he took it home, and it started not wanting to boot consistently. When you press the power button, sometimes it will do nothing and sometimes you'll get the startup sound and then a black screen. If you unplug the power and battery and let it set for a few minutes, it will many times go ahead and boot. The only thing that is consistent is that it's not consistent. Another thing we noticed is that there is a several second delay between the startup sound and when the gray screen with the Apple logo appears (that is when it boots). The gray screen used to appear pretty quickly.
    Any help would be appreciated!

    try zapping the pram and reset the power manager.

  • PowerBook G4 froze, won't boot, black screen

    I have a PowerBook G4 1.67GHz (DL-Hi Res) running OS 10.5.8 with 1GB of RAM.  It has been a great machine; reliable with no major issues throughout the years and still fast for its age.  Unfortunately two days ago the screen came to a complete freeze and since then I haven't been able to boot into its OS. 
    In particular, that afternoon I visited the Weather Channel web site and then left the house.  When I came back three hours later, I found the screen frozen at the Weather Channel site.  The mouse cursor would not move, the clock (on upper right side of the screen) was also stuck at 4:10pm, which was about the time when I last used the computer, and the fan was running faster than normal but not spinning out of control; moreover, the laptop felt as warm as when I stream live video from the Web, not hot though.  Since the computer was unresponsive I decided to turn it off by pressing and holding its power button for several seconds.  I should mention that there was nothing connected to the computer when this happened and that there was nothing that was installed, updated or upgraded recently.
    When I attempted to turn it back on, the sleep light came and stayed on, the startup tone was heard once, the fan started running at normal speed and the optical drive did its normal startup spin; meanwhile, the screen was pitch black and stayed like that.  Five seconds later the optical drive did its normal startup spin again; five seconds later it did it again and then again and again.... and it kept doing it every five seconds until I shut the computer off by pressing and holding its power button.  I am not sure whether or not the hard drive was spinning during the startup.
    Any ideas what the problem might and how to revive my powerbook (if possible)?  Any help will be greatly appreciated.

    Tom, thank you very much for replying.
    I read the links you provided and here is everything I've done so far to revive my powerbook:
    - Started up without the battery (though the battery is fully functional)
    - Started up with the battery installed
    - Started up in Single-user Mode
    - Attempted to reset the PRAM
    - Started up in Safe Mode
    - Tried to get into the Startup Manager
    - Attempted to reset the PMU
    - Started up in Open Firmware
    All of the above attempts failed to produce any good results.  Each time I tried to start up the laptop, the sleep light indicator would come and stay on, then came the chime (except for two times), the fan would run at normal speed and the optical drive would keep doing its startup spin every 5 seconds until I would shut the computer off.
    Here is the last thing I tried... Since I was even unable to get into Open Firmware I decided to press and hold the power button, as suggested by one of the Apple Support documents, until the computer is forced to boot into Open Firmware.  Instead of the Open Firmware what I got was a brief high-speed spin of the fan, fast blinking of the sleep light indicator and a single deep, somewhat loud and long beep.  What I just described lasted for a few (maybe several) seconds and then the sleep light stabilized, the chime came on and the optical drive started doing its thing every 5 seconds.
    Any more ideas / suggestions?

  • Powerbook G4 500 won't boot from battery only

    Hi,
    I have a Powerbook G4 500 Ti (running OS 10.4.8 that will not boot from just the battery without the powercord attached. I have tried several different batteries and the same results.
    Sometimes under "About this Mac" the battery show's it's there but most of the time it doesn't show a battery and an X appears on the desktop.
    What I've done - replaced the battery with a fully charged one from a working PB, reset the PMU, Reset the Pram, Cleaned the contacts on all batteries and in the battery bay, Reseated the Airport card, Down loaded the latest Apple updates today and loaded them.The computer runs great with just the powerchord and sometimes the battery icon shows a picture of a plug, but then it reverts to the X.
    Another problem, I have a working Airport card installed from another machine and it doesn't show up in the About this Mac window I get Airport Card: No INFORMATION FOUND that it is installed. Could this be related and also can a dead PRAM battery cause this? Any help would really be appreciated I've tried everything. Thanks for your response in advance.

    Hi, Opie. A dead PRAM battery will generally prevent a Tibook from starting at all, with or without the AC adapter or a main battery in place. Therefore, I doubt that that's your problem.
    Your Airport card cage and your battery are both connected (separately) to the Powerbook's main logic board. it is possible for those connections to work loose over time, or to be hindered by oxidation on the contact surfaces. You can try disconnecting and then reconnecting each of them several times to wear away oxidation and make sure the connectors are properly seated.
    This page is the starting point for a complete, well-illustrated set of take-apart instructions for the 500MHz Tibook. The bottom illustration on the page that shows how to remove the keyboard shows the battery connector: a large white plug with several multicolored wires attached, directly beneath the keyboard's left-hand Command (Apple) key. The last illustration in the instructions for removing the Airport card shows the card's connector: a rectangular tan or orange tab at the right-hand end of the flex cable that is connected to the Airport card socket. While you have the bottom cover of your Tibook off, check to make sure the card is firmly seated in its socket and that the flex cable is solidly connected to the logic board.
    Another possible reason for the battery's not being detected sometimes: Some 400MHz and 500MHz Tibooks had an ill-fitting battery: it slopped around in the battery compartment and could lose contact. Apple offered for some time to install free of charge a small shim that took up the slack inside the battery compartment and kept the battery pressed against its contacts. If that correction was never made in your Tibook, or if the shim has fallen out or shifted from its proper position, your Tibook may be suffering from the original problem now. Check to see that there is no movement of the battery once you snap it into position in the battery compartment. If there is any, post back for guidance on making and installing a shim. (Apple long since discontinued the repair program, and it's a simple thing to make yourself.)

  • Powerbook g4 dvi won't boot

    when powered on, the light on the power adapter is green, the battery charges, if i press the caps lock on keyboard it light up green, but there is no chime and no further boot.
    so i changed the ram, switched the slots- no differnce and the ram works in my pc based laptop.
    took the bottom apart and removed the logic board. cleaned the dust, put it back together without the screws and bottom case. boots and works fine for few times, sufficient enough to run diagnostics with apple hardware test and the logic board passes along with ram etc., boots into os with hard drive, the airport card works. behaves as if nothing is wrong.
    happily i put together the screws and the case cover-- same problem. does not boot. when powered on -- no cd start, no chime, no boot.
    my guess-- the lid close switch is stuck but i could not find it?
    any other suggestions are welcome.

    Hi t,
    I believe eww is correct that it is not the sleep switch. As he mentioned earlier, you need to look closely at the bottom cover to see where something is coming in contact with it. Note: it may be that the short (as you have surmised, I'm quite sure that's what it is, the question is where it is) may be a conductor coming into contact with the bottom cover, OR it may be that the bottom cover is pushing something else up, causing a short in another area. The fact that you have to remove/install the logic board to get it to boot again after installing the bottom cover seems to suggest this latter possibility, that once something is forced out of place by the bottom cover, then it must be "dislodged." Tolerances in these PBs are very tight.
    Or, it may be your theory that a circuit has to be reset is correct. To test, try resetting the PMU, and if that doesn't do it, try unplugging the power adapter, removing the main battery, removing the bottom cover, and letting it sit for about 10 minutes, then, without the bottom cover on and without removing/installing the LB, power up again and see if it will boot. If it does, this would seem to confirm the "circuit reset" idea. If not, I would lean towards the idea that the bottom cover has pushed something out of place, causing a short.
    As for a fix, to start, I would lay the PB upside down, display closed, bottom cover off, static precautions in place, and lay a straight edge across the bottom to see if you can determine where contact is being made. Also take a look at the bottom cover itself to see if it has been pushed in at any point. Post back with results.

  • Powerbook G3 (bronze) won't recognize battery

    Hello all,
    I recently purchased a replacement (main) battery for my Lombard (NewerTechnoloy), and even though it indicates a full charge when I press the button on the side, my Powerbook shows a red "X" through the battery icon.
    I've tried the battery in both the left- and -right slots with similar results.
    Can anyone suggest something for me to try?
    I'm trying to understand whether this new battery is the problem -- my old battery was the original Apple manufacture, and will not hold any charge at all.
    --Bill

    It could be a defective battery. You should contact NewerTech & get a replacement.

  • IMac G5 won't boot, external interrupt error

    I started my iMac G5 and did get the chime but it automatically goes into OF mode. The fans run loudly and it continously scrolls an "external interrupt" error with a bunch of jargon that goes by so fast I can't read it.
    I tried resetting SMU, none of the bootup key sequences work, I can't boot from disk and it won't go into target disk mode. I've searched online "external interrupt" which has been an issue for others, but haven't found an answer to the problem yet.
    I just tried resetting SMU again. This time I got the chime again, but now have a black screen. After about 30 seconds of nothing the fans start running and the screen remains black. Help please!

  • Intel iMac won't boot & Disk Utility error-can't verify disk

    I posted earlier today that my 24" intel iMac (2.4Ghz Core 2 Duo) froze yesterday after a Safari crash. I had to shut it down with the power button. Since then it won't start up. Sometimes it starts, then shuts off. Other times it starts, then the little gear just spins. I've done the keyboard commands for RAM, the complete disconnect of power, then reconnect, and the Disk Uitility with the install disk. When I do Disk Utility to verify, it gives me a red-letter error that it cannot verify on both verification checks. I have also tried, via the install disk, to repair by using a Time Machine backup, but that utility has been spinning and spinning on my Time Machine for hours, and I cannot even click the "Continue" button because it is busy (checking the time machine?) 
    I am out of ideas as to how to move on from here. My AppleCare expired 2 months ago, so that's a problem. I've had no major issues before now, except for earlier this year when Mail wouldn't open for some reason. Anyway, I'm at my wits' end here. I NEED my Mac. I'm disabled and have no better source of entertainment or socializing. My hobbies are editing audio, video, & photos. Without my Mac, I'm just in the middle of the sea in a raft with no oars. Any helpful suggestions will obviously be much appreciated. Thanks.

    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

  • MacBook Pro won't boot up. read error 0x7  failes to load a number of drivers?

    Dear All,
    Lately I am having quite a bit of trouble with my Late 2011 MacBook Pro. It seems to be stuck in a vicious circle of boot-ups.
    Since a couple of days it is taking ages (like 5 min) to boot up, and today it just doesn't get to te "user-screen" anymore.
    I have tried to boot it in safe-mode and tried to enter the repair utility, but those don't seem to work.
    When I tried booting it in single-user mode, it told me it had "read error 0x7" and it fails to load a whole number of drives.
    When I run a Fysical System Check, it tells me the Macintosh HD can not verified?
    What can I possibly do to get back in there again? are all my documents lost?

    This may work if the drive is OK. If it's accessible but corrupted try the second procedure.
    Reinstall Lion, Mountain Lion, or Mavericks without erasing 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.
    Repair
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
    Reinstall Mountain Lion or Mavericks
    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X
         Note: You will need an active Internet connection. I suggest using Ethernet
                     if possible because it is three times faster than wireless.
    Install or Reinstall Mavericks or 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.
    OS X Mavericks- Erase and reinstall OS X
    OS X Mountain Lion- Erase and reinstall OS X
    OS X Lion- Erase and reinstall Mac OS X
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.
    And, it neither work consider my original suggestion.

  • Won't boot after Update Error

    Hey there. Just yesterday I ran the software update utility. I had 3 things to update.
    It asked me to restart the computer at the end. I clicked on the restart button.
    It went to a blue screen with an update install progress bar.
    Then I got an error box saying that an unkown error happened and asked me to restart the system.
    I clicked the restart button on the box.
    Now it hangs at the apple logo with the spinning "gear"
    I booted it in single user mode and ran fsck, no errors were reported.
    I booted in Verbose mode.
    It gets stuck at
    "DSMOS has arrived"
    I let it sit for 3 hours, it just stays at that one spot.
    EDIT:
    If this indicates anything I do get this one error that it hangs on for a while in Verbose mode boot
    "AppleBCM501Ethernet: 0 0 setFixedSpeed - logic error, speed any?
