I've been trying to restore an old 233Mhz g3 (wallstreet, I believe), and I've been running into problems booting to the install cd. I'm successfully able to get into open firmware, but I don't know how it is refering to my CD drive. Can anyone help?
Also, I don't have an OS 9 or OSX cd, although I may be able to find one. But because of this, it would be best if any cd boot solutions did not involve any operating system (this computer also has a clean drive)

Thanks,
trekkie

    Trekkie,

    The original Powerbook G3 Series (Wallstreet) install CD had a green label and was named so; the Wallstreets came with either a special MacOS 8.1 or a general-release MacOS 8.5.1. Any general-release, retail MacOS 8.5 > 9.2.2 is supported as is OSX up to 10.2.8. Press the 'c' key to boot to CD.

    A few questions and comments...

    -Do you hear the startup chime?

    -Does the Wallstreet automatically boot into Open Firmware or are you pressing the 'command-option-O-F' keys at startup? If the former, reset the PRAM and see if it will boot normally. Wait for two startup chimes before releasing key.
    http://docs.info.apple.com/article.html?artnum=2238

    -If you still boot into Open Firmware after resetting the PRAM, try resetting parameters in OF:

    Boot into Open Firmware by holding down the 'Command-Option-O-F' keys from a cold start while the chime is being played. You will see a command-line screen...enter these commands:

    1. At the Open Firmware prompt, type: reset-nvram
    2. Press Return.
    3. At the Open Firmware prompt, type: reset-all
    4. Press Return.
    Example:
    0 > reset-nvram
    Press Return
    0 > reset-all
    Press Return

    The reset-all command should cause the computer to restart. If this occurs, you have successfully reset the Open Firmware settings.

    -If still having problems and you have two RAM modules installed (upper and lower slot), test each one individually. Bad memory may cause a boot into OF.

    -A working Wallstreet will start in this manner: power on > startup chime > depending on amount of RAM installed, 10 - 45 seconds of memory check > display lights up and HD spins up > OS starts to load.

    Let's see your results before making any other suggestions.

    One of the problems with the wallstreet is that the rom disk drive software can address only 8GB. If our are using OS9 or earlier this makes no difference because the first thing the OS does is load the disk driver from the HD And there are versions of that driver which will handle any size drive. Any other OS you install must install a driver before accessing anything not in the first 8 GB. This may include determining the size of the drive. The way OSX handles that is to require that the first partition is totally in the first 8GB. How some other OS would handle it I don't know,

    Trekkie,

    The Wallstreet never had any firmware updates so that would not be an issue. I understand you are not trying to install a Mac OS but I thought I would mention the different OSes the Wallstreet supports just to see if you could get it to boot from the optical drive.

    Even though your Wallstreet booted to OS 9.1 before the HD swap, corrupted PRAM can prevent a boot to CD, thus the suggestion to reset the PRAM.

    If you cannot boot the original software install CD, you may have corrupted PRAM or a bad optical drive or a bad CD or possibly just a dirty lens in the optical drive.

    Your Wallstreet should boot to the original install CD even without an HD installed; in fact startup will proceed as usual sans HD and you will see the blinking '?' as it looks for a bootable volume. This might be one test to see if your replacement HD is causing a problem.

    There are a few HDs made specifically for a PC laptop that will not boot a Mac due to firmware; Toshiba made one such HD.

    Your other points regarding Open Firmware commands and netbooting are beyond my knowledge. All I can suggest at this point is take a stab at the Unix Forums at Apple and see if you can get any help.

    Trekkie,

    The older optical drives such as the one in the Wallstreet can read and usually boot CD-Rs but not CD-RWs, plus your observation of using 650MB instead of 700MB is valid. I have burned bootable 9.x CD-Rs on my MBP and they will boot my Wallstreet.

    Correction: burned 9.x CD-Rs on my iBook, not MBP.
