hmm don't know if you have had a chance to look at modifying the updater yet dougg3, but i decided to have a dive into the updaters with resorcerer, more specifically looking at the data fork (not expecting to find anything, as i have never done this kind of modifiaction myself...), and near the end there is what seems to be a list of firmwares:

Code:
Apple iMac Open Firmware 3.0.f8 built on 08/06/98 at 12:04:16 Apple iMac Open Firmware 3.0.b2 built on 09/17/98 at 15:19:23Apple iMac Open Firmware 3.0.f3 built on 12/02/98 at 10:25:41
so i took a look in the 1.2 updater and sure enough near the end:

Code:
Apple iMac Open Firmware 3.0.f8 built on 08/06/98 at 12:04:16 Apple iMac Open Firmware 3.0.b2 built on 09/17/98 at 15:19:23 Apple iMac Open Firmware 3.0.f3 built on 12/02/98 at 10:25:41 Apple iMac Open Firmware 3.0.f9 built on 02/03/99 at 16:45:21 Apple iMac Open Firmware 3.0.f10 built on 03/05/99 at 21:14:19 Apple iMac Open Firmware 3.0.f1 built on 04/01/99 at 16:47:10
so presumabley that is the firmware whitelists? the thing that is throwing me is that firmware updater 1.0 has firmware 3.0.f3 in that list, which is firmware update 1.0?

or i could be compleatley wrong, as i say, i am no expert
