In doing a fresh install of OS X Tiger on my emac, can it be done by a disk image of Tiger or do I have to use the CDs? Reason being the CD thingy is not working.

Or, do I have to sacrifice the fresh install and use a USB Drive to upgrade it?
 
I believe you need to use a CD as there is no way to keep the disk image mounted throughout the installation process.

The CD has to be used, how should the eMac read from the .dmg anyway without an OS.

Try Target Disk Mode with one of your other Macs and try to have access to the other Mac's DVD drive.

That is if I do a clean install right? But, can I mount a disk image to the current OS X in my eMac and upgrade from there?

In any case, I like the Target Disk Mode suggestion.
 
No, as the Mac OS X has to restart and boot into the installer.

To use TDM, it would be best to use the iMac or MBP in TDM and use the optical drives in there.
If you use the eMac in TDM the iMac and MBP will not boot from an old Tiger DVD.

Understood...thanks...so in other words, using TDM, my iMac's drive will function as the eMac's drive correct?
