Sounds to me that you dont quite know what this device is for?
It lets you change between two kickstart chips by pressing ctrl-a-a for more than 5secs, so you can for example have both 1.3 and 3.1 kickstart and shift between those. There is no need to modify the kickstart roms.
Misunderstood what I meant. (I do know what the Kickstart switcher does, switches Kickstarts.

)
On Rev 5 motherboards, if you're putting a Kickstart (I believer greater than 1.3) you need to short a couple pins, and rewire another for compatibility.
I was wondering if the same had to be applied to the Kickstart ROM switcher, or would shorting the jumper on the lowerleft corner of it, make the changes so I wouldn't have to rewire the Kickstart ROM.
