1.) Insert the jumper block into the DATA-position on your EF3
2.) Turn on your C64 with EF3 (black screen)
3.) After that hold the C=key (hold it pressed)
4.) Press the middle button on your EF3 and release it.
5.) Thats it, now you are in Basic.
6.) Load Easyprog from Disk or SD2IEC and select <Menu> <Write CRT to flash> <System Area> and choose "ef3-init-1.x.x.crt" and flash it.
I have done the above and everything worked perfect until i tried to copy the ef3-init file to floppy, it doesn't fit. Any suggestion would be apriciated.
