Try to update the iMac G5 DMG 10.5

I have an old iMac G5 with 10.4.11 on it. He has a bad CD drive and can't seem to even a superdrive Apple CD/DVD, when connected by USB. So I a. My 10.5 installation disk DMG file. First I tried to copy it to a Firewire hard drive, but the iMac won't even see the drive (FW tab in everything it sees Mac nothing), although two other Mac (Intel), he can see very well.   I also put on a USB key, but when I run the update to 10.5, it is said to 'restart to start' and then just restarts in its 10.4 normal on the internal drive. What Miss me - how this DMG to upgrade my iMac 10.4? I also see that the iMac can start on the network; is there a way I can get one of my other Macs to serve the 10.5 update via network to begin out of that? Or, can I do the USB drive (32 GB) a real startup disk and start the iMac that?

Most of the PowerPC Macs can start up of external hard drives, FireWire (not USB).  Former ports USB2.0 (even if) may not provide enough power for a USB optical drive, if it is powered type current by USB (not its own power supply).  And it would not work for this purpose, because it is USB, no FireWire.  This is why the USB flash drive does not either, at the start of the iMac.

It may have to this external FireWire drive.  What type of disk external drive FireWIre is?  Is this a record 2.5 inches which is powered by the FireWire port, or a 3.5-inch disk addition which has its own power supply?  The type with its own power supply is better, don't count is not on the port for power.  Is it directly connected to the FireWire port on the iMac?  If you have more than one FireWire cable, have you tried more than one (to rule out a defective cable)?  FireWire 400 (older type) or FireWire 800 (new type)?  Either should work, as long as you have the right cable.  What type of port the iMac FireWire has?

If you can get it recognized by the Mac, you can use disk utility to 'restore' the .dmg to the FireWire drive file.  The FireWire drive should be cleared to have the Map of Partition Apple partition scheme and format Mac OS extended (journaled), be bootable with a PowerPC Mac.
