Identifying a mod

A600 motherboard shot at BBOAH

Could anyone identify what's the mod connecting a switch to both the RAM upgrade and a kickstart ROM leg?

I assume it's a mod for switching between "1MB chip RAM+kick 1.3" and "2MB chip RAM+kick 3.1".. Or something like that.
I guess there's either an EPROM or kick 2.04 under the kick 1.3 chip that you can see on the picture.

Thanks 8bitbusy. I'm keeping an eye open on any A600 mod out there as I'm working on mine...
