Help PowerBook 150 not Run disket flash Question mark System 7.5.3 - 18 parts.

PowerBook 150 not Run disket flash Question mark System 7.5.3 - 18 parts. Please Help !!!

Hi,
First of all, in order to verify whether the 7.5.3 system software files are of the type earlier downloadable from Apple (with one large image file split onto floppy-sized segments), could you confirm that the first of the eighteen files has a file name with ".smi" at the end (before .bin or .hqx), and that the remaining seventeen files each include ".part"? The US version had totally nineteen files (one. smi and eighteen .part), but as I indicated above, this was different depending on language version.
If the PowerBook 150 is empty (without an operating system), you will need a startup floppy. Do you have access to a Disk Tools floppy for the PB 150? A Network Access Disk 7.5 floppy would be useful under all circumstances, and can be used as an alternative startup disk (and the system folder could be copied to the hard disk, and would then act as a temporary system). The problem today is that Apple's older software downloads list, which contained the Network Access Disk 7.5, does not appear to be available any more.
If you have the NAD 7.5 file already, the normal way of creating a bootable floppy was via a utility called Disk Copy (on another Macintosh computer with a built-in floppy drive). Disk Copy 6.3.3 can still be downloaded (https://support.apple.com/kb/DL1262). The Make a Floppy command under the Utilities menu is used to create properly sector-copied floppy disks. Please note that the Disk Copy utility is not needed or used to mount a self-mounting image (.smi).
There were special methods allowing an NAD 7.5 floppy to be made through a Windows PC as well (using a Windows version of StuffIt/Aladdin Expander and a utility such as WinImage).
It is also possible to obtain a version of StuffIt Expander for the PB 150 through a PC (but the PowerBook would need at least a temporary operating system first). With access to an older Windows PC (capable of running a DOS program) with a floppy drive, you may want to try the following: Prepare an empty PC-formatted 1.44 MB diskette via FORMAT A: in DOS or the "full" formatting option under Windows. Download the MACDISK.EXE file from http://rrzs42.uni-regensburg.de/Macintosh/files/macftp.html . Run this MACDISK.EXE (DOS) program on the Windows PC. Follow the instructions on screen. The result will be a Mac-formatted (sic!) floppy that could be moved to and used with the PB 150. This floppy contains a StuffIt Expander installer. Once installed, drag downloaded .bin files onto the StuffIt Expander program icon to decode them.

Flashing Question Mark on Sawtooth

Hello. I've got an upgraded Sawtooth that I'm having problems booting off the Hard Drive. First off, here's the system:
Sawtooth G4 (AGP Graphics)
Sonnet 1000/2M G4 upgrade
1.25GB of PC133
Flashed ATI 9800 PRO w/ 128MB RAM
DVD-ROM - I don't remember what brand
350Watt ATX PSU converted for use in Mac
Generic no-brand PCI-to-USB2.0 adapter (5port)
ACARD ATA133 PCI-to-IDE card (w/ large HD support)
200GB Maxtor ATA100 Hard Drive
USB RaLink G Wireless Adapter (sometimes - shared with eMac)
Notes: Fresh PRAM battery and extra fan installed about 4 months ago.
The first 3GB of the drive is partitioned for OS9 (for legacy support), but I don't have anything installed on it. The remaining (like 186? GB) has Tiger installed on it, with iLife and all available updates. My little brother uses it for light gaming, and recording himself playing the guitar w/
GarageBand.
Anyways, I had a problem a month or so ago where it stopped booting properly, and would sit there flashing a question mark/floppy drive. I could boot off the 10.4 install cd, and the drive would show up fine. Choose Start-up, select that disk, and it would yield the same results. So I did an archive and install, and it worked fine. Ran the same updates to bring it to 10.4.11, had to re-install iLife (they stopped working after that, even after the 4.11 update), and went on my way.
Well anyways, now it's doing it again. It just sits at that flashing question mark for hours. I can boot off the CD, and the drive passed verification and permission checks. Nothing has changed since last time it booted fine, and when it decided to do this again.
I've tried everything that I can think of, either from here or past experience. Removed all extras; removed the unneeded PCI cards (can't boot off the 200GB w/ out ACARD PCI card); reset PRAM; reset-NVRAM; OF reset-all; verified OF date&time; reset the PMU; unplugged it and left it w/o a battery for 48 hours. Nothing has worked.
Does anyone have an idea that can help me out? I've worked on plenty of Macs in the past, G3s to new Intels, but I'm at my wits end on this one. Even if I do reinstall and update, is there something that is incorrect, maybe w/ the driver for the ACARD adapter that is causing it to write to the HD incorrectly when it shuts down? IDK, and if you can help me, please do!

The flashing question mark appears when your Mac cannot find:
The preferred OS Type {macOS, Linux, BeOS, Joe's garage shop special}
Of the preferred Version {7.5.3, 8.1, 10.4, 0xFF}
On the preferred Startup Disk { ATA 0 Master, SCSI 0 drive 6, device 0xFF}
All these things are stored in the Parameter RAM. If the power fluctuates, even for an instant while your PRAM Backup battery is weak, it may allow corruption to creep into those parameters.
A good battery should measure over 3.2 Volts in Hand, a little less is OK when measured in-circuit with the AC power plug removed. Anything less should be replaced. They are available from online vendors for as little as US$8 delivered, or from Radio Shack for US$20+.
A PRAM Reset with the tiny button is required after replacing the battery.
A bad battery is much easier to fix than any of the other problems you could be having. Make sure the battery is good first, because a weak battery makes all other debugging more difficult.

MacBook Pro 13 2010 running Mountain Lion: will not boot and shows a folder with a flashing question mark. Will not start in 'safe mode' i.e holding shift on start up - nor can I call up any utilities with the OSX shortcuts. Any thoughts?

Following an automatic update, the machine wouldn't boot. Screen came on (shows white) - then either showed a 'No-Entry' Sign and a spinning cog, or a folder with a qusetion mark. I tried to start the machine in different modes ( eg. holding shift after the tone ) but nothing worked. after leaving the machine alone for 1 hour. It worked perfectly again. I did a 'verify disk' check which found no problems. 2 hours later it then froze ( In - Photoshop). Could not force quit, so shut down, and have not been able to boot again since (white lit screen - flashing folder with question mark) . I have also taken the hard drive out and checked the connections which seem fine. Any suggestions? - Is the Hard Drive dead. : other info : It was also running parallels 8, with Windows 7. at the time of the update....

Flashing Question Mark Folder Everything I Am Trying is Not Working!

A few days ago my iMac gave me the "pinwheel of death" so I cold shutdown and rebooted. I heard the chime and then I got this flashing folder with a question mark on it. I quickly jumped on my Macbook pro and researched what it meant. I tried booting while holding the option key and would get a blank white screen with a mouse pointer and nothing else. I tried resetting my PRAM and still nothing! Then I saw someone say to restart my iMac while holding down R to start into disk utility. It worked! I went through the repair disk process and it said there was nothing to repair. I then repaired disk permissions, and bingo it had to repair a few different things that needed to be repaired. Once the repair process finished I rebooted to my main drive and everything worked fine. That night I shutdown my computer and the next morning I got the flashing folder again. This time however, after shutting down and rebooting everything worked fine. Now today my iMac froze and I cold shutdown and rebooted. I got the flashing folder and question mark again. This time nothing is responding. I tried rebooting while holding the option key, tried booting into disk utility and still nothing. The only thing that the iMac will recognize is when I reboot while holding the 'option' key and put in the Mac OS X Lion install disc It lets me click that disc and it starts the install cycle... I really don't want to do this as it would wipe everything on the drive and I do not have a lot of documents backed up. What do I do? Am I screwed? Help would be greatly appreciated!
Thanks much!

I think the HD has crashed. Run Apple Hardware Test in Extended Mode at least 3x back to back. If it reports errors, next step is your local Apple Store or AASP. Also carefully read and apply Apple's advice in Flashing question mark appears when you start your Mac. If you had been backing up it would have been a simple matter of replacing the HD, restoring from the backup and you're back up and running. Considering you said you don't back up you're about to learn a very painful lesson on why backing up isn't something you should do it's something you MUST do.
Good luck and sorry for the bad news.

IN DESPERATE NEED FOR HELP flashing question mark appears MacBook

Hello everyone, I got this White MacBook Mac OS X 10.4.11 yesturday I was updating limewire and iTunes, I was downloading some songs from Limewire when all of a sudden my macbook frozed. I was not able to do a thing. Not even minimizing nor quiting the app nor even opening another aplication, so I decided to shut it down by holding the power button until it shut down (about 8 secs). So I restart my macbook and I got this grey=blank screen whit a flashing question mark on it. I've tried EVERYTHING on this link http://support.apple.com/kb/TS1440?viewlocale=en_US even these one http://support.apple.com/kb/HT1533 and all I was able to accomplish, was to hold the mouse (/trackpad) button to eject a Cd, and while pressing Shift during startup (in order to start in Safe Boot mode) all I get is this lock image and this space to type a password. I've tried typing every password I know and I can't fix my macbook. Can anyone please help me out on this one?

It means certain system files needed for startup are corrupted. You will have to reinstall OS X. If your hard drive is unaffected you can try the following:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger.) 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 quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

HELP PLEASE-- flashing question mark on startup, none of remedies working

I'm using my Powerbook one night, everything is working fine. I wake up, go to use it and I get the spinning color wheel; tried to close an application by force quit and I get no response, so I restart using the power button, and the flashing question mark / mac OS icon pops up.
I immediately did some research on what to do; I put the OS cd in, tried restarting holding the C key and later the X key; nothing. Tried resetting PRAM, didn’t solve the problem. Tried holding command-S to check disk/repair, didn’t work. I then held the option key to choose the location to boot off: and neither the HD nor cd showed up: just the circular arrow to re-scan, and the straight arrow to enter the selection.
I have 2 install discs: I'm not sure if they are the same or not; I may have put the wrong one in. So I tried to eject it and now it wont eject.
Firstly, how to eject the cd? I tried holding the eject button, F12, command + . , as well as the trackpad. I don’t see a place to put a pin or paperclip in like some cd drives have to force it open.
Secondly, what else can I try to get my computer working? I'm no expert, but it sounds like this might be a hardware problem aside from the HD, being that the computer is not recognizing neither HD nor cd. However, the cd I have is a copy of the OS disc I made, and it may or may not be the right install disc, or properly made copy.
How difficult is it to open up Powerbooks and replace the HD? I'd like to have it up and running as soon as possible, but most importantly I hope that my data is still safe. And no, unfortunately I hadn't backed up my data. Please advise.

Maybe the copy of that disk is not bootable. Do you have the original or can you get it?
Here's a faq to remove disks.

Help. iMac flashing question mark, and now power loss at startup.

Hey. I've had some really weird issues with my iMac. It's a 2.8 core 2 extreme aluminium 2007 iMac. It was bought for me at the end of august 2007.
What happened was, I was watching a movie and it started freezing. Everything was so slow. So I turned it off by the mains since it wouldn't shut down. When I tried booting it back up it had the flashing question mark. So I read up on it and tried doing what the apple support website recommended, which was to put the install disc back in and use the disk utility to repair the disk. Except this wouldn't work and it said the hard disk could not be unmounted. So I read up again and apple recommended resetting the PRAM, which I did and then it wouldn't recognise the hard drive AT ALL. But after a few tries of booting up it found it again, I got on disk utility and still said the same thing when I tried to repair. So I repaired the permissions instead and restarted and the computer booted as normal. But then was still very slow and freezing. So I opened disk utility one more time and tried repairing permission, restarted the computer and now when it gets to the apple logo and the loading icon it looses power and goes blank. I've already tried resetting the SMU. it didn't work. Has anybody got ANY clue to what I can do? Is my waranty up? I don't have AppleCare. Any help would be appreciated. Thanks.

If you have an Intel iMac, it has an SMC not an SMU, so if you used the procedure that says "SMU" on it, you used the one for an iMac G5, which is not an Intel iMac.
Since you did many different things in a somewhat random order, you may want to do the following, even if you did some of it already.
Reset PRAM
http://support.apple.com/kb/HT1379
If that does not help, reset SMC
http://support.apple.com/kb/HT1543
which is basically disconnecting ALL cables and power, then reconnecting using a precise procedure. If you have been connecting the power cord to a crowded or old power strip (surge suppressor), try connecting it directly to the wall outlet, at least initially. First, power it up with nothing connected, except for power cord. If that works, add just your keyboard/mouse and use it that way for a while to evaluate how the iMac is working. If all is well, connect your other peripheral (USB/FireWire) devices one by one. If the problem does recur at some point, identify the device added last; it may be faulty or causing some kind of interference.
If the problem remain, even when trying to start up the iMac with nothing but power cord connected, connect just your keyboard/mouse. Insert your Mac OS X installation disc (for the currently installed system) and restart with the C key held down. Sounds like you did this already. You should note if the iMac is running normally when booted off the installation disc. If so, the problem may be your internal drive; it may be faulty. Run Disk Utility from Installer's menu bar, and try to do a +Repair Disk+ again. See if it works any better this time.
You can also try using the Apple Hardware Test, including on your original disc(s)

The blinking question mark indicates that the firmware could not find a valid Operating System on your machine.
Your harddrive may have failed. Your filesystem may have bcome corrupted.
You may want to seek professional help here. You need to decide how important you data is to you. Be sure to specify that you want your data back.
In addition to the fix your mac places, there are professional firms the will attempt to recover data from a failed harddrive. Recovery does not come cheap.

Flashing Question mark: New hard drive not working Macbook Pro late 2008

After following several peoples advice on this forum I decided to upgrade my Macbook Pro late 2008 with a Seagate (1TB) Solid State Hybrid Drive 2.5 inch.
Heres the device.
http://www.morecomputers.com/spec.aspx?pn=ST1000LM014
After creating a mountable boot on a External hard drive with Mavericks install I removed the current hard drive and replaced with the new seagate drive. However it didn't seem to recognize the external hard drive (it is quite old but works perfectly) and went to a flashing grey question mark screen and wouldnt do anything else. Ive tried holding down command-r and option-r but I get nothing. Its just the same flashing question mark. I have done this several times and the same result.
I put the old drive back in and it works fine.
I am trying to work out is the problem with the mountable external hard drive OR is it the hard drive is not compatible with my computer?
Appreciate your help
Gary

Sorry I think you may be confused.
I am trying to install the new Seagate hard drive to my mac (not as an external hard drive).
I replace the macbook pro hard drive with the seagate drive:
http://www.morecomputers.com/spec.aspx?pn=ST1000LM014
I then started up the machine with a usb external hard drive with a boot copy of mavericks on it. However, it just displayed a flashing question mark and wouldnt start booting the osx.
I am trying to work out is the problem with the mountable external hard drive OR is it the hard drive is not compatible with my computer? Im guessing it must be hard drive. Would it be better to use a USB pen drive as the external hard drive is quite old?
Does anyone know what the problem could be as the hard drive is brand new.
Appreciate your help
Thanks, Gary

HT1379 A flashing question mark appears when I re/start my MacBook Air 2013. At first, I pressed Power & Option button and it recovered from Internet. Then, four options appeared but none of them are helpful. Could u please help me to solve it asap?

Hello,
A flashing question mark appears when I re/start my MacBook Air 2013. Then, I pressed POWER & OPTOIN buttons and internet options appeared for internet recovery. After internet recovery, the OS X utilities appears with four options (Restore from Time machine, Reinstall OS X, Get help online and Disk utility). But none of them seemed helpful. On the last option Disk utility, the icon created only with 33KB and other disk 1 Mac Os X Base system. On First Aid, the icon Repair disk is disabled. So I could not click on repair disk. Could you please suggest me how to solve this problem asap? Thank you so much for your help in advance!

You can try the following:
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.

You must use the original grey system DVD disc that came with your iMac to run the Apple Hardware Test, the one that is marked with instructions for running the test on it. Depending on the version of OS X that shipped with your iMac, this could be either disc 1 or disc 2.
When you restart with this disc in the optical drive & the D key held down, you should not see a question mark icon or the leopard installer. If you do, it means that either you don't have the correct disc inserted, you waited too long to depress the D key, or you are releasing it too soon.
You don't say exactly which Core 2 Duo iMac model you have. If it is a Mid 2007 or later model, use the chart at Apple Hardware Test: iMac (Mid 2007) and later models to identify the AHT version you need. That version number should printed on the grey disc you need to use. You can't use the instructions there to start the test from the hidden HD partition if the HD is dead or damaged but the ones for running the test from the Install DVD should work fine.

PowerBook 145B shows pic of floppy disk with flashing question mark

I recently discovered a PowerBook 145B in my garage. When I turn it on, it makes the start-up sound but then goes to a blank screen with a picture of a floppy disk with a flashing question mark.
I don't have any of the original floppies that would have come with it. Is there anything I can do to make it work?

Hi,
The technical specifications for the PowerBook 145B can be found here.
Although the original operating system was 7.1 (not free), you could try System 7.0.1 instead (see KB article TA33972) instead. System 7.0.1 is available for download from Apple (for example, US and British versions). Access to another older Macintosh computer (with a built-in floppy drive) would normally be required in order to create properly sector-copied floppies from disk images. If absolutely necessary, the British version (which is provided as individual images) can even be used to produce the system disks on a PC (using a special technique).
System 7.5.3 is also available (e.g., US and British), but may not be ideal for a computer with a small hard drive and limited RAM. A boot floppy (use the Network Access Disk 7.5 here) is not included in the 7.5.3 download.

Help with FLASHING QUESTION mark when starting the mac

Hi All,
My mac just froze,i had to do force shut down,when i restarted it i had the flashing question mark.Did all the instruction that are given in the site:restarting with the installation CD and then using the *disc utility*-BUT i could not find the hard drive that i need to do the "repair disc " on.So i did what the document said and i reset the PRAM-still my hard drive does not show up in the disc utility.I also tried to reset the SMC but again -same result.
please please try and help me,is my HD doomed? is there anything else i should try?

I have the exact same problem.
Today, when I turned my macbook on, it was so slow, that I decided to restart it. When I turned it on again, I got the folder with a questionmark in it on the display. Tried to put the installer CD in, but it couldn't find the HDD. Ran the Disk Utility, which said: "Invalid node structure" and "Invalid record count".
I think the HDD is "destroyed", because it makes strange sounds. But how? And why?
The Macbook isn't even a year old.
Any help?

Help diagnos. flashing question mark on monitor, cannot boot from CD drive

Any ideas? This is an older G3 tower which was "souped Up" wtih USB and Firewire cards, memory
Mac froze in midst of work last week. Now only get flashing question mark supermimposed on image of a floppy drive.
Tried to re install system (OS9) but cannot get ANY CD to boot from CD drive. I reboot, hold down "C" Key with CD in tray ( and i can hear the CD drive working). But the tray opens and ejects/rejects the CD).
I now suspect the problem is NOT the OS but rather a hardware issue.
Am I correct in this assumption? what else could this be?
I am trying to help an older gentleman who has no backups and has some important documents on the HD.If I can boot up, might be able to retrieve those itesm. (and get a newer Mac!)

Not the answer,Dale (thanks anyway)
I read that article.
I cannot boot from any bootable CD.
Inserted the OS install disk as well as third party bootable CD.
with CD in the CD drive tray, I restarted and held down the C key.
Mac restarted but the CD tray popped open. Would not boot from the CD.
That is why I posted query
not only do we have the flashing question mark but bootable CDs are not booting this Mac. So I can do no diagnostics, no repair, not salvage of files.
I am trying to understand where the problem lies. am guessing Hard Drive failure but why should CD also not work?
