Burning Eprom for A2000 with kickstart switch

Hi, i have my A2000 with a kickstart switch 1.3-3.0, but this switcher has 2 separated Eprom low and high for 3.0 kickstart version and the socket for original 1.3 kickstart.
Now i need to upgrade with the 3.1 or 3.1.4 version but i don't know the procedure to burn the two new Eprom with a file of 3.1 version (probably i need to split this file in low and high, but i don't know what is the software or method for this operation).
The Eprom now installed are both AM27C020-150ns.
Please help me.
Thanks

I have compiled the file .cpp on mi macbook with the command and the file split are in teh folder, now if i launch this command only one abnormal file is writed and the name is xaa.
I have launched with this command on terminal:
split kickstartromfile.rom
But i don't know if the split tool need any arguments before file name.

Ah you are running split the system command.. not the command you just compiled.
Call it like ./split <filename>

No use the A500/600/2000 3.1 rom. It will boot but i think the A1200 rom expects AGA.
