"Instructions for Installing the Firmware
I seem to have forgotten one important part of this website. How to actually install the firmware!
Download the firmware you wish to install. All versions are based on the OEM Canon 1.1.1 version. The instructions for upgrading the 300D firmware are identical to those required to install a modified firmware.
Instead of the .fir file you download from Canon, use the .fir file from the mod site. All steps are the same.
Be sure that you do not attempt to write a compressed version of the firmware, such as .rar or .zip, You will need to uncompress and extract the .fir file first!"
Basically its a firmware update. you download to an CF Card, put in your camera, boot it up, and it says "UPDATE FIRMWARE" Yes / No... you update it and keep playing.
if your unhappy, you can roll it back
PS. "30D Firmware Hacked to Run on 20D!"
