IMac 266 starts at firmware prompt

Good afternoon,
How do you boot from a cd when the iMac 266 starts at a firmware prompt? I'm trying to install OS 10.2
Thanks

I agree with Gran Maestro. I bet you are getting the yaboot prompt. Doesn't yaboot let you type x to get to Mac OS?
It is suggested that you install the latest firmware when running Linux on the machine and when running Mac OS 10.2 or 10l.3. You may need to be running Mac OS 8.x to install the firmware.
What firmware do you need?
http://docs.info.apple.com/article.html?artnum=86117
The iMac 266 will run up to and including Mac OS 10.3 if you have the latest firmware installed.
Your powering off the machine, holding down the c key, then powering on? You have a disc that you know will work in the machine. You need a disc that will work on all macs or a disc that came with the machine. Have you tried re-boot the Linux disc?

  • Another hard drive swap question - re: 8GB partition for OSX in iMac 266

    I have a Tangerine iMac 266 that I am setting up for a neighbor's son. The original 6GB hard drive was toast, so I swapped in an old 10GB drive that had previously been removed from an iMacDV 400. The 10GB "new" drive had OSX 10.3.1 and OS 9.1 on a single partition. I am aware that these early iMacs need OSX in a first partition of less than 8GB, so I expected that I would need to partition the "new" drive. However, while I was loading an install CD after powering up, the iMac booted fine into OSX, despite it NOT being located in a first partition of less than 8GB (and has continued operating well - booting multiple times in OS X and 9, surfing the net, etc...the only weirdness is a refusal of Word X to run).
    I thought this was impossible, and in researching this I found that the Apple support site says that, for this computer, "Mac OS X must be installed on a volume that is contained entirely within the first 8 GB of its ATA hard disk." see http://docs.info.apple.com/article.html?artnum=106235
    My Questions:
    Is the 8GB limit only related to iINSTALLING OSX on these machines (and not RUNNING OSX)?
    Will the machine run into problems later if a portion of the OS (i.e., during an update) gets installed outside of the first 8GB of the disk?
    One of the log files says that the driver is out of date for the RageproC, and Classic applications that require more than 4MB of VRAM say that I don't have enough VRAM to run, yet the iMac has 6MB of VRAM (2 on MB and 4 in slot as listing by the system profiler) - do I need to (or should I) reinstall the system software (I already tried loading the latest ATI drivers, but it did't help)?
    P.S. - to add more data points on the subject of RAM upgrades in these iMacs, my iMac 266 would not accept a 256MB PC-100 SO-DIMM that worked fine in an iBook and in the upper slot of a Rev. A iMac 233. Well, it accepted it, but only recognized the first 128MB.

    I believe Duane is correct. Even with Mac OS 9, you can run fine as long as all OS components used during startup are within the first 8GB of space. However, (even with Mac OS 9) as soon as something used during startup ends up beyond that limit, you will get open firmware or a gray screen at startup. The Mac OS X does not allow the installation target to exceed the limit as a preventative measure, not because it won't work at all.
    The best "non-technical" explanation I have heard as to why, is this... The IDE hardware (and its driver) can only "see" the first 8GB of space during the initial start up process before the OS is loaded. Once start up completes, control is handed to the OS, which can see the entire drive. Therefore, apps have no problem running from beyond the limit. Only components needed before the hand-off is constrained to the 8GB limit.
    FYI - On my iMac and 120GB drive, 7.78 GB (as shown in a Finder window) is the precise point where the Mac OS X Installer allows the volume to be the install target. "Precise" to with a few hundred MB's.

  • Imac 266 booting sequence

    I have an imac 266 with 160 MByte of memory, 20GB disk with 10.4.2 and the firmware 3.0 f3.
    Each time I boot, I enter in the openfirmware prompt.
    with printenv I can see the value of the nvram variable boot-command equal to "0 bootr".
    When I reset the firmware default with reset-nvram, I have for the value of boot-command : "mac-boot", it's the right value to boot to mac osx 10.4.2.
    Now if I enter the command reset-all the imac boots normaly and I have the 10.4.2 desktop.
    OK. Just fine.
    If I restart the computer, I enter in the openfirmware prompt and the nvram variable boot-command has a value of "0 bootr".
    It seems that somwhere in mac osx a conditional path go to a command writing the nvram with a bad value for the variable boot-command.
    Can anyone help me ?
    Thanks

    The 266 MHz IMacs are incompatible with Mac OSX 10.4.2 you are maybe right, but Mac OSX 10.4.2 runs perfectly on this old timer.
    I have also other Mac Computers (macmini, powerbook titanium, imac 400MHz etc ..) and many others computers (sun, PC etc.) and this one is for the fun.
    In 1980 I ran unix on a computer with a 8" floppy as swap partition and since this time I have learned that unix is very flexible and programable
    I plan to upgrade the memory to 512 MBytes, I have upgraded my disk with a old 20GB 7200 rpm
    The 266 MHz is a good configuration for browsing the web and have my email ( and I repeat it works very well for that).
    I have just the little problem with the boot sequence and I am shure It may be solved.
    best regards
    Pierre

  • My Imac doesnt start after de pasword, It continuos asking for it again and again, what can I do to start it?

    My Imac doesnt start after de pasword, It continuos asking for it again and again, what can I do to start it?

    First, make sure caps lock is not on.
    Another reason why your password might not be recognized is that the keyboard layout (input source) has been switched without your realizing it. At the login screen, you can cycle through the available layouts by pressing the key combination   command-space or command-option-space. See this support article.
    If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
    Otherwise*, start up in Recovery mode. When the OS X Utilities window appears, select
              Utilities ▹ Terminal
    from the menu bar at the top of the screen—not from any of the items in the OS X Utilities window.
    In the window that opens, type this:
    res
    Press the tab key. The partial command you typed will automatically be completed to this:
    resetpassword
    Press return. A Reset Password window opens. Close the Terminal window to get it out of the way.
    Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
    Select
               ▹ Restart
    from the menu bar.
    You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.
    *Note: If you've activated FileVault, this procedure doesn't apply. Follow instead these instructions.

  • Intel imac wont start after changing permission

    intel imac wont start after i changed my hard drive permission to let me read and write, then i clicked apply to all enclosed files.i turned it off no problem. then it never started up again in os x. the grey screen with apple logo appears,then after a minute it restarts, and will keep doing that if i let it. i can start up in windows xp, but i dont know how to do anything in windows xp that will affect os x. i can use the hard drive in target mode, but i cant figure out how that can help me. i use a macbook to view target disk. ive spent hours looking through help and support. finally i do not have the os install disks. PLEASE HELP!

    My apologies for the inept instructions.
    Restart normally. Open Terminal in the Utilities folder. Paste the commands in the Terminal application to avoid typos:
    sudo su
    Press RETURN. Enter your admin password when prompted.  It will not be echoed to the screen. Press RETURN again. Now paste each of the following at the prompt and press RETURN after each.
    chown root:admin /Applications
    chmod 0775 /Applications
    chown root:admin /Library
    chmod 1775 /Library
    chown root:admin /System
    chmod 0775 /System
    chown root:admin /Users
    chmod 0775 /Users
    chmod -R -N /Applications
    chown -R :admin /Applications/*
    Again, my apologies.

  • Bondi Blue iMac 266 wont turn on at all.

    OK, WELLLLLLL, i know you guys probably see this kind of thing everyday. i looked around the forum through all those "imac wont start" pages and none help. mine seems to be a different problem. ill try to give as much info as possible.
    ok, i push the main power button, it chimes, HD spins up, everything seems just fine then click click click, and the whole thing goes off (no it doesnt boot up and monitor is just off, the whole thing goes off). if i remember correctly, the power light never turned green, and if it did it was for a short time. after it does this, pressing the power button does NOTHING, no noise at all.
    i have 2 other identical macs so ive done a little experimenting (the other two work flawlessly) first i tried just swapping the computer out (not the board, the whole slide out thing, cdrom, hd logic board and all) that didnt work. while i had it out, i tried the computer part from the problem mac, in the other case (the one i knew worked) it worked, but when i installed some updates and restarted, it wouldnt come back on. it did the same as the other the power button did nothing, no noise whatsoever.
    so im confused as ever. seems like both parts are broken haha, the crt part AND the computer.
    blah, im gonna fiddle around with it a little more see what i can do.
    any ideas??? (ALSO, it says 10.2 but honestly i have no idea what os this imac has, but im pretty sure its 9.1)
    iMac G3 (CRT) 266 MHz / 512K Cache/32 MB/ 6GB HD/24x CD-ROM/ RAGE PRO / 6MB SGRAM/ modem   Mac OS X (10.2.x)   Bondi Blue/Green W/E it is haha

    ok well just to clarify it a little bit, i just took the board out unhooked it all removed battery memory, etc (not cpu though), put it back in, plugged it back up, hit the power button. it chimes, hard drive spins up, the light is orange the whole time, then right as the light turns solid green i hear a click and the whole thing goes off and wont turn back on. also, i tested the battery and i think its dead. would a dead battery cause all of this????

  • Imac 266- getting past login trouble

    OK so I found this Imac on the side of the road. To my surprise when I got it home it boots right up. It appears to be from a college and a sticker on it says login 9 Password 9.
    Silly me I believed the sticker and went ahead and bought a keyboard for it. Keyboard is brand new made for OS X. Anyway the password doesn't work so I'm still stuck at the login screen. My only option that doesn't require a password is to shut down.
    Since I don't have another mac or mac software I decided the easiest way to go is to download a copy of yellowdog Linux and go with that and keep my investment low. After all, I just want this thing for my kids to mess around with. Its a handy package. I attempted to boot to the YD CD by holding down the C key but no dice.
    The CD drive appears to be working as it sounds like it accesses the CD while booting but still boots to the HD. I looked up some of the boot commands and tried them to force it to boot from CD but no love. One site I visited posited that tray loading Imacs cannot boot from CDRs. This seems to be the case but I further could not get it to boot to anything other than the HD despite any of the keyboard boot commands I tried. I could get it to boot without extensions but that got me no further than the log in screen.
    I'm now assuming that that it cannot boot from a CD-R and went ahead and ordered an original 9.1 install disk from new world computing.
    Now between the keyboard ($30) and the OS ($40) I am now into this "free" machine for $70 and there are nicer ones available online for $100 shipped.
    OK enough babbling on to my questions:
    Is it possible that the new keyboard is not entirely compatible explaining why I can't seem to do much with boot commands?
    Can anyone confirm that tray loading Imacs cannot boot from CDRs? I'm really afraid that the OS9 disk is going to arrive just to find out that the problem was a faulty CDROM all along...
    I'm really inexperienced with macs- Is there something obvious I'm overlooking in trying to get this thing going?
    Thanks in advance for any tips/advice
    Imac 266   Mac OS 9.0.x  

    The disk arrived today and I was actually able to boot with the cd and delete some extensions/files so that I could boot directly into OS 8.x.
    Installation of 9 required a firmware update that went without a hitch. Now that I've gotten 9.1 in I'm having terrible trouble getting it to update to 9.21. Everytime I try it gives me an error 127.
    I looked up this error and it seems that initializing the disk with a fresh install should solve the problem but it doesnt. Disk Utility says the disk is good.
    This error comes when I try to install the north american English update. Is it possible the disk I have was international and this is causing the error? The only other thing I can think of is a bad ram chip - but I only get an error on this one update- everything els has been smooth. Any suggestions appreciated

  • Install 10.3 on iMac 266 Stops at spinning circle after "Preparing Install"

    I have an iMac 266. I'm trying to install OS X 10.3 on it.
    I got it with 32MB of RAM. I tossed in some memory I had around and got it up to 256MB. (Two 128's.)
    Boot from OS X 10.3 disc 1.
    Grey Apple logo appears with spinning circle thing under it on white background.
    It waits about 2 minutes.
    System spins up CD-ROM drive and screen turns to blue background with mouse arrow. A box saying "Mac OS X: Preparing Installation" appears with a progress bar. (There is still a mouse arrow.)
    That box disappears and is replaced by another spinning circle thing near the bottom-center of the screen. The mouse arrow disappears with the box.
    The system stays that way. The spinning circle thing animates and does nothing further. I've switched CD-ROM drives as well.
    I've also tried installing various Linux (for PPC) operating systems to see if they can point to any problems for me.
    -SuSe 9.2 PPC
    -Mandriva LE2005 PPC
    -Yellow Dog v4.01
    The only one that installed was Yellow Dog.
    I would rather have OS X.
    What is the deal here? I've spent 3 days on this so far...
    I'm actually also a Mac newbie at this point. It's been years since I messed with my last Mac.
    Be gentle. LOL
    iMac 266   Mac OS 9.2.x   256MB Memory, 6MB VRAM

    You can install OS X on a 6GB drive, but it's really too small. Unfortunately, the iMac you have requires OS X be installed in a partition or drive less than 8 GBs. One particular reason why the iMac you have is not that well-suited for OS X. It's too slow, doesn't have the video horsepower, and OS X can't be installed on a volume larger than 8 GBs. However, if all you want to do is play with it you certainly can.
    Do the following:
    1. Boot from your OS X Installer Disk. Insert the OS X installer disc in the optical drive, restart the computer. As soon as you hear the chime press and hold down the "C" key until the computer starts up from the CD. After the installer loads select Disk Utility from the Installer menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Set the number of partitions from the dropdown menu to one (1). Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
    After the above is completed quit DU and return to the installer. Now proceed with the OS X installation.
    Regarding the hard drive jumpers, they should be set for MASTER. The iMac only supports one internal hard drive.

    How much free space do you have on your hard disk? And have you ever performed a backup & clean install after an OS X upgrade?

    Just the other day my iMac has started doing something very annoying: It starts up with a white screen and a gray progress bar, and it takes a long time to start. It does this each time I start it now. I have not added any new hardware/software. Any ideas?

    That usually only happens if you had to manually force shut it down. See http://support.apple.com/kb/ht3964 for details.

    To close them all quickly, hold down the Option key while clicking the close button (red bubble) i one of the windows.
    Make sure they are all closed before quitting Numbers.
    Quit Numbers before shutting down or restarting your Mac.
