Basically the title. I have a G4 MDD that I have been trying to figure out how to use. I have come to like that I can clone my installs between machines, and use target disk mode pretty often, as well as firewire in general.

Is it just not in the firmware? I read that for some other models they just didn't have it, but I'm sort of confused by that. If so, is there a way I can get the current iboot image (2013) to install over the apple OFW? (2003)

I can take a drive out of another machine and put it in this one and have it boot, and I can boot by CD/DVD, but nothing else works.

thx

I'm not real clear on the issue you are having, or what you are trying to do?

Please be more specific on the exact steps you are taking, and what/when it fails.

I don't know what an "iboot image" is, but you say "2013". That would be an Intel Mac?

You can't use a disk made for an Intel Mac on PowerPC, unless you are using a dual Binary that is made for x86 and PPC.( Mac OS X Server 10.4.6 Install Disc or Mac OS X 10.5.x Leopard Install Disc )

If you connect a 2013 Mac in Target Disk Mode to a MDD and try and boot from one of the HDD's with the Mac OS installed on the 2013 Mac, that is NOT GOING TO WORK.

First PPC Macs like the MDD can't read the partition map( table ) of a disk formatted for an Intel Mac.

Next only two versions of the Mac OS are compatible with PPC( PowerPC ) and
x86( Intel ). That would be Mac OS X Tiger( Server ) and Mac OS X Leopard. YOU CAN NOT INSTALL either of these two versions on a Intel Mac as new as 2013.

Generally you can use TDM( Target Disk Mode ) form in Intel Mac with a DVD drive. So if you insert the Mac OS X Tiger Install DVD or Mac OS X Leopard Install DVD( retail not OEM copies ), into the DVD drive of the 2013 Mac then you boot it into TDM that install disk should show up in the Boot Picker of your MDD and you should be able to install from it.

There are edge cases, but you're going to have to be specific about what Mac OS X version you want to install, what hardware you have, and how/why you need to use TDM to do it?????????


The MMD generally supports Mac OS 9.2.2, Mac OS X Jaguar 10.2.x, Mac OS X Panther 10.3.x, Mac OS X Tiger 10.4.x, and Mac OS X Leopard 10.5.x ).

Some configurations of the MDD didn't support booting Mac OS 9, but there are work arounds that will allow them to boot it and install it.

Some configurations of the MDD may need versions of Mac OS X Jaguar newer than some retail install disks. I.E. if you have a Mac OS X Jaguar 10.2.0 install disk, you may need a newer one such as 10.2.3 ).
 
I wantr to CCC my powerbook to my G4 MDD. I turn the MDD on, hold T, MDD turns off
 
This usually happens if you have your drives hooked up to something other than the built-in IDE bus. If you load target mode from Open Firmware then it will compain that it connot find a device right before powering down.

Hmmm......

From what I have seen, holding the "T" key to enable multi-boot( Boot Picker ) normally invokes the Boot Picker even when no disks are present. It should scan for a while, and it may have a "shutdown" timeout after some specified time, I don't think I ever waited long enough to test that.

I think after a while with no input Open Firmware on some Mac's has a specified "shutdown" time, but all I can recall is when using telnet in two machine mode with Open Firmware the target Mac will stop responding after a while if there is no input in the telnet session, however the target Mac does not power down.

Also, an improper Master/Slave/Cable-select setting on the IDE buses can have unexpected results.........
