Panther to Tiger Problems

[5stargeek]

Ok, so bare with me i may get confusing here...

years ago i got 10.4 Tiger to upgrade my emac and it installed fine with no problems. For compatibility issues with software i had at the time i needed to reinstall back to 10.3 Panther. However due to gaining new software im now in a position where i can now upgrade to Tiger once again!

Unfortunity even though I have exactly the same installer discs and emac i had before its now decided not to work.

When i restart with the installer disc it now Kernal Panics with a message that begins with the sentence 'Unable to find driver for this platform:"PowerMac4,4"

Any ideas what could have happened over the years to cause this?

was this your only mac ever since or did you have another eMac in between
as i would just say you are using the wrong discs , as i know it happens when you use the grey installer disc from a powermac 6.4 (thats the 1.25 or 1.42 ghz eMac) and you try to install on a powermac 4.4 (thats the 700,800,1ghz eMac),

it even happens if you try it with the powermac 4.4 discs on a 800mhz ati model if you have the disc for the 800mhz nvidia model or the other way round

Nope same Mac, same discs... which is why im so confused

maybe firmware update ? resetting pram?, thats the only things i could think of at the moment as i never had this problem before ,
and i have done the same on my eMac and on my iMac g3 several times to see which one is best tiger or panther for my Mac`s (eMac running tiger and iMac g3 running panther now )
so as it worked without problem , i can only have a rough guess what could cause it
but one thing i never did update from one to the other os i always did a clean install and i have the retail disc`s for each os , but that should not make a difference
