rockstar-plus Level 1 (5 points)

I picked up a used eMac a couple weeks ago, but as it used to belong to a school, it has a lot of junk on the HD. To clear it out, I thought I would use FireWire TDM. It runs Panther 10.3.9, but for some reason, WILL NOT boot into FireWire Target Disk Mode. It has a wired keyboard, and I can boot into Single User Mode, Verbose, Safe boot etc, but not TDM.

eMac, Mac OS X (10.3.x)

    Do you have any other Firewire Devices connected?


    Some USB devices can intergere alo.

  • rockstar-plus Level 1 (5 points)

    No other FireWire devices, only USB mouse/keyboard.

    Just noticed the 10.3.x


    So we know more about it...


    At the Apple Icon at top left>About this Mac, then click on More Info, then click on Hardware> and report this upto but not including the Serial#...

    Hmmm, I find no Firmware updtes needed for eMacs which is one thing that can prevent Target mode...



    Have you done a PRAM reset, CMD+Option+p+r...



    Does it boot into Open  Firmware with CMD+Option+o+f ?



    reset-nvram (press Enter)

    set-defaults (press Enter)

    reset-all (press Enter)


    Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...


  • rockstar-plus Level 1 (5 points)

    I have never done a Firmware update, as when I bought it, ran Software Update, all updates for Panther/eMac had already been installed.
    I'm not quite sure about PRAM battery, as I live in New Zealand and am not really sure where to get them here. Pressing either of those key combos does nothing, the Mac loads Panther as if nothing happened.

    Recap on start keys:

    FireWire TDM: NO

    Verbose: YES

    Single-User: YES

    Safe Boot: YES

    PRAM Reset: NO

    Open Firmware: NO

    All key combos that don't work simply result in the eMac ignoring the key combos and standard-booting Mac OS X.

    Is this a USB or Wireless KB?


    Well, ifyou can' find them there, though I'm certain many places must have them, OWC does ship worldwide.


    Click on that link, add to Basket, Estimate shiiping charges & choose New Zealand & your Postal Coce.

    As described in original question, it is a wired keyboard.

    I would, however, like to make sure that it is PRAM battery at fault.

    There isn't a way to check the level in the battery is there? I don't want to replace a perfectly good battery, and for all I know, it could have been replaced last month, I only bought the thing 3 weeks ago.

  • BDAqua Level 10 (122,227 points)

    Well, besides it being about the cheapest thing to try, if you have a voltmeter you can check it with a 1K Ohm load & see what VDC it records.

  • rockstar-plus Level 1 (5 points)

    I'm sure that would work if I actually HAD a voltmeter.


    As from what I have read in Time, volume, startup disk, DVD drive region code, Console info etc. don't change upon reboot, so something tells me it isn't the battery. Even after I left it unplugged for 2 hours when I cleaned the case down (schoolkids!)

  • BDAqua Level 10 (122,227 points)

    Another way to tell is in SystemPreferences>Date & Time, uncheck set Date &Time automatically, Shutdown, wait, restart... what does Date &Time say it is?

  • rockstar-plus Level 1 (5 points)

    Upon going to try this, I have discovered it was already unchecked. And I must restart the eMac three times a day sometimes. Every time, it shows correct time, date, time zone etc. I don't always restart it with connected internet anyway, as the eMac doesn't have an AirPort Extreme card installed.

  • BDAqua Level 10 (122,227 points)

    Likely not the problem then... but how does it connect, Ethernet?

  • rockstar-plus Level 1 (5 points)

    When it's in the living room, when I shift it into the family room to let the kids use it, it's offline. My primary computer is a early 2011 i7 MacBook Pro 13". (Obviously has Airport Extreme built in).
