What is Zeus?
Zeus is a Mac GPU Flashing Tool. It can write a new firmware on to your graphic card.
But it can do much more then that. You can patch your drivers to add support for excotic cards,
install injectors by Netkas, and save the firmware from your Nvidia card.
Zeus is the replacement for ATI Flashing Tool.
New Features in Zeus:
Modify 4870 / 4890 firmware to add EFI
Disable Power Warning
Overclock some Nvidia cards

My thanks to specially, Netkas, Rominator and Pipomolo for providing with key elements in creation of this app.
My even more special thanks to Donaters, for without them the app would have stayed at ATI Flashing Tool 1.0
You can donate to Zeus and it makes me very happy.
