I have put onto the PCB "Kickstart 1.3" for ROM1 and "Kickstart 2.0/3.1" for ROM2.
But, you can use the Kickstart Switcher like this:
- ROM1: KS1.3 or KS2.0X & ROM2: KS1.3 or KS2.0X or KS3.1
The only restriction is for KS3.1 which must be onto ROM2 with jumper JP1 closed.
But, it's not a problem, because the Kickstart switcher allows to choose onto which ROM (1 or 2) you want to boot by default by using JP3-1 (Priority Selector).
The jumper JP2 is used to select the reset time to swap between kickstarts (3 or 10 seconds).
