Is it possible there are firmware updates to be applied to the 3rd iMac? I would be inclined to check this and then run Bootcamp's first stage again. I believe the first stage changes some information either in EFI or the boot sector - you may find that deleting the Windows partition & recreating it performs this "magic". > as for the 2 macpros, both hang when the installer asks me to > confirm that i really want to install windows xp. the keyboard > doesn't respond, and the "caps lock" light turns on on the keyboard. Not using bluetooth keyboards, by any chance, are you? In any case, generic USB keyboards can be bought for very few pounds - it might be worth a go trying to install with one of those, just in case they make a difference. Finally, for both the 3rd imac and for the MacPros you should unplug as much additional hardware as possible during the bootcamp process. Any additional USB devices should be disconnected and PCI cards removed from the Pros. Stroller.
