From what I understand, none of the files provided by Sonnet are 'drivers'.
They are not additional software added to the OS to run the card.
Again, from what I understand, which may be incorrect, the Sonnet card was manufactured without a 'ROM' on the card - the Sonnet software copies the ROM from the original Apple CPU and then writes that to the Sonnet card, making it bootable/workable.
Therefore, there should be no drivers/extensions involved here.
Since this process has already been performed in the past by a previous owner of this upgrade, it should not require anything new and should work (which it technically does - including firewire) - and also does not allow me to run the software again, since it is a one time operation.
And yet - it's benchmarking, and performing, like a G3/300 and acting weird.
