I don't see how this can void your warranty since you are not modifying
the
hardware in anyway that runs it beyond what it was designed for. What
you are doing is simply changing 4 bytes in the driver which then just
skips the card ID check and just provides access to everything the Card
states that it is capable of doing. You are not even flashing the bios
on the card, hence there is no way NVIDIA could know what has been done
hence you would still be covered under warranty. Besides, at less than
$100 does it really matter if the card goes wrong?
As regards pirating of drivers you are not doing this, you are simply
replacing 4 bytes from one of the DLL's and hence from what I can tell
by reading the Licence you are not in breach. The person who originally
reverse engineered them is breaking the law but that is a different
point entirely. I am not responsible for that.
As regards the ethics of it I don't see a problem at all. Nvidia is a
business selling a product, I am the customer, I bought their product
thus it belongs to me and I am free to modify it to my hearts content as
long as I don't want their technical support and don't sell it on in a
way that breaches their patent. This is a free market and all is fair in
love and war. If you are really worried about the ethics then by all
means spend 5 times more than you need to, I will sleep more soundly at
night knowing that I didn't waste $400 when I didn't need to.
Yours Sincerely
Ross
