To my knowledge there are no special ROMs in an
InfoServer other than
the standard MV3100 console ROM, and it's what lives on its boot disk
that makes it an InfoServer.
I know that InfoServer code can be booted on either a uV3100 or
a VS3100 (or maybe both, I forget the exact details) but there's
some setting of bits that needs to be done at the console (I've
forgotten these details too ...). Without the bit setting, the
code will not run on a non-InfoServer box.
So I suspect that the ROMs are different (at least to the extent
of having a different SIDEX burned in there) since that would be
the easiest way of detecting the box type.
Later InfoServers moved away from the KA41/KA42 platform, so
things may be different on later software versions.
