Hey guys ...

 

my G4 eMac has a flashing question(?) mark.. so i tryed to reinstall mac osx and i did..

 

i place the install DVD in a NON-Mac DVD-RW Drive (Could this be the problem?) and i hold/press "C" and wait nothing happens.. just gose back to

the flashing question mark... but if you are going to tell me to do these..

 

1) Hold "OPTION" = Just a purple back ground with 2 Button "Refresh&Arrow'

2)Hold "C' = NOTHING HAPPENS

3) reset nvram = computer resets and gose back to the flashing ?

 

SO I have TRYED them ALL..

 

AND finaly i try OPEN FIRMWARE....

 

i try to boot the cd by typing ...

 

0 > boot cd:,\\tbxi Cant OPEN: cd:,\\tbxi.

 

and another way

 

0 > boot cd:9,\\:System\Library\CoreServices\BootX can't OPEN: cd:9\\:System\Library\CoreServices\BootX

Can't open device or file

 

and some thing else

( if you really need to know ask me..)

 

 

 

so from them above is there problem with the DVD-RW or something else

    i place the install DVD in a NON-Mac DVD-RW Drive (Could this be the problem?

    It could be, not all external drive are bootable, is it Firewire or USB?

     

    boot cd:,\\tbxi Cant OPEN: cd:,\\tbxi.

    If you go into open firmware and type: devalias

     

    What does that report?

     

    "OPTION" = Just a purple back ground with 2 Button

    That generally means the Hard Drive has died or is royally messed up.

     

    Restart your computer, hold down Command-s and type in the following:

     

    /sbin/fsck -fy Enter

     

    /sbin/mount -uaw Enter

     

    Any action at all?

  • kithusan Level 1 Level 1 (0 points)

    Thank you SO much for you reply..

     

     

    *Well here are the results for the things you told me to do?*

     

     

    1) is it Firewire or USB? =  None.. its a built in one...

     

    *Details About the DVR-RW

    *Brand  : NU  < (click NU for the picture)

     

     

    i change it to this DVD-RW because the install DVD is a DVD (daa)

    but the mac did have a CD-R in it before i change it with the DVD-RW

    Details:

    Brand : LG CD-ROM ( and has apple logo on it)

      

    2) Open firmware and type: devalias? = ( only some of the important ones are here).

       

        *CD : /pci@2000000/mac-io@17/ata-3@20000/disk@0 

        *HD : /pci@2000000/mac-io@17/ata-3@20000/disk@0 

        *USB0 : /pic@f2000000/usb@18

        *USB1 : /pic@f2000000/usb@19

     

     

    3)Single user mode... dose NOT work. the computer just gose to the flashing question mark

        (is there a way to get to single user mode using open firmware?)

     

     

    Thank you 4 your time

  • BDAqua Level 10 Level 10 (120,940 points)

    My guess is that the DVD drive needs a Junper change & is the whole problem since both the HDD & CD report ata-3@20000/disk@0

     

    If the CD.DVD is jumpered Master, then try Slave...

    Yeah, jumpers could be it.

     

    I am also curious as to what version of Mac OS X you are trying to install, and what the specs are on the eMac. From your other post, it sounds like you might be using an intel only install, which won't work, or Mac OS X 10.5 Leopard which requires minimum specs that your eMac might not meet (but it should likely boot to some point).

    thanks you for you reply..

     

    Yes!! i am trying a DVD with virsion 10.6.4 .... but if i can get it to boot then.. i try some thing else

     

     

    BUT how do i change it to slave (only option i have is open firmware) and i dont have a jumper wire connected to the dvd ?? (Could this be the BIG problem)

  • kithusan Level 1 Level 1 (0 points)

    thank you also...

  • Elite Expert of all Knowledge Level 1 Level 1 (40 points)

    Yes, 10.6.4 will not boot on your eMac. It will not install. It will not run.

     

    You will need 10.4 or 10.5 (might work with even earlier versions depending on the model). If you do try 10.4 or 10.5, then you need to also make sure you meet the minimum requirements for RAM and CPU speed. 10.4 requires 256MB to run, and 10.5 requires 512MB and 867MHz or faster processor. The earlier eMacs were 700 and 800MHz, so won't run 10.5 without some jiggery pokery.

     

    As for the jumpers, these are on the back of the DVD drive near the ATA cable. Changing these on the internal drive means taking apart the eMac.

     

    Alternatively, you could install Mac OS X 10.4 or 10.5 on an external firewire drive, plug that into the eMac, and boot from it. This means you could install on a different Mac.

    Thank you...

    so now i will get mac osx 10.4.11 for the mac.

    and Not sure about the jumpers...So the DVD-RW i have has no Jumpers...

    So your telling me is i should put one if i dont have one......

     


  • BDAqua Level 10 Level 10 (120,940 points)

    Do you see the jumper pins on the CD/DVD drive next to the IDE cable connector? Are there any jumpers on it now?

     

    Is there a label on the CD/DVD drive showing Jumper settings?

  • kithusan Level 1 Level 1 (0 points)

    Here are the thing on the back of DVD-RW...

     

    *Power

    *IDE Interface Connector

    *CSM SLA

     

    Audio. Digital & Analog

     

     

    is the jumper wire CMS SLA ( and if it is the one it has no wire going to the mac)

     

    and also where in the motherboard dose the wire plug into

     

    & Thank you

  • MichelPM Level 6 Level 6 (10,110 points)

    It's NOT a jumper wire, but a small, plastic block that acts is an isolator on certain pins located next to the long IDE connector.Is there a block there and is configured to cover certain pins?

    There should be a diagram on the drive, somewhere, that shows where to put this plastic jumper block to cover certain pins that tell the computer that the drive is acting either as a master or slave drive.

    If the block is missing, you'll need to find one, get one.

  • BDAqua Level 10 Level 10 (120,940 points)

    There are no wires involved, just a little jumper block that shorts out two pins...

    like you told me i look at the back of DVD and there was one of this (<the gray block).... and also i haved old DVD-RW and got 3 more of them (the gray blocks)...

     

    at the back of the dvd-rw there a three pins... so should i block all of them.. or just one or two

  • BDAqua Level 10 Level 10 (120,940 points)

    You normally use just one jumper across two pins vertically, right below SLA or whatever it says for slave.

     

    : : : [:] :

     

    Though to complicate things, some dries use no jumper to indicate Slave.
