Zeus Flashing Tool
Zeus is no longer developed and supported, use at own risk
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.
Thanks
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

ATI:

HOW TO MAKE 4870 / 4890 ROM:

With the ati card inside, and drivers installed in windows
