Caution!

For the patch to work, the BIOS version is more important than the SCPH number.

It is only possible to inject the code via ISP!

|

For the patch to work, the BIOS version is more important than the SCPH number.
|

|

The delay in starting up caused by the bootloader of the Arduino cards prevents the injection of the BIOS patch within the delay,
|
||||
that's why you have to use the ISP which eliminates the bootloader.
