Kernel panic when I insert and restart OSX tiger CD

Question

I have a slot loading imac PowerPC G3 DVD-ROM drive, 256MB RAM and 10GB HD, which shipped with OS9
I have been using it like this since I bought it, but in recent months it had slowed, crashed a lot etc and I thought it was time to get it up to scratch.
I wanted to upgrade it to OS X tiger, but having done little to maintain my imac over the years thought I better get into good shape before I tried.
Disk first aid had identified a problem with the startup disk which I could only seem to resolve be reinitializing the startup disk from my original CDs. So did this.
I also erased and restored OS9 from the original software restore CD.
I tried to upgrade to tiger straight from OS9 and got into terrible trouble losing image on screen. (attached a borrowed monitor to do repairs)
I then downloaded from the apple site OS9.1 OS9.2 and OS 9.2.2 and installed in order (because I didn’t have CDs I just opened the downloads and installed from there)
I also downloaded new Firmware 4.9.1 and upgraded this.
Screen problem resolved, but now trying to upgrade to tiger from OS 9.2.2 encountering a different problem
Insert tiger CD – big X appears and a button to restart – press this and imac begins to restart – grey screen appears and dark grey apple then stops and a kernel panic (white in black) appears saying
Panic (cpu0 caller ox002de020) unable to find drivers for this platform “power Mac 2,1”
Loads of other text/numbers appear including “backtrace” etc
Until it comes to
Panic: we are hanging here
Everything freezes at this point and I have to restart the computer from the restart button and forcibly eject the CD with a paperclip in the force eject button.
Having deleted everything early on I now have no other software installed on the computer other than supplied with above.
And I detached all peripheries before trying to upgrade
Been working on this for days and am getting nowhere, can anyone help?

Hi Rod
Have you tried running Disk First Aid again (from your original Software install CD) since erasing the drive?
to do this should I boot to the CD by holding down the C key and run disk first aid from the utilities folder on the CD? Am I alright to do this from the OS 9 CD even though I've upgraded through the downloads to OS 9.2.2?
defective, damaged or dirty Tiger DVD
How could I test this? I do have an ibook running Panther but I'm reluctant to get that involved as its working fine and storing a lot of my files while I sort out the imac.
or a DVD drive that needs cleaning
It could be this, how do I clean the DVD drive?
Is there any possibility that an "open firmware password" is set on this computer?
Not sure, I don't think I've set one, how would I check?
I recently bought the Tiger DVD new from Amazon and the RAM is all original Apple RAM.
thanks for your help
