2nd nic for island network

Microsoft Windows vista ultimate w/ sp1...

Specs: Windows Vista
I have added a second nic into my PC which I would like to use for 2nd island network to connect to a machine controler board.
I do not like to have any traffic other my communication to this machine board on this nic, and I do not like to have lots of broadcast/multicast communication on this line as I like to have full bandwith and some kind of realtime behaivor.
Additionally I would like to have a fixed IP addresses here (like 10.0.0.1 and the board 10.0.0.2) so there is nothing to configure about it. The second nic is for the PCs internet and intranet so there i will use DHCP or what ever some user might want.

Is there a way to do this and keep that island network configuration hardcoded configured ?

Easy.
Crossover cable between pc nic and board nic
statically assign the ips on both with no gateway

ok sounds easy but what about IP adresses.
is it possible to use 10.0.0.1 without knowlegde of destination network topology (I mean it could be a used address at customer site) or are the addresses of 2nd nic + board automaticaly not visible in the intranet of the PC if I remove the gateway ?
I have read somewhere that windows Vista always does some kind of routing between 2 nics and I read somewhere else that this routing is disabled if network class (subnet mask) do not match ?
Has someone informations regarding this ?

Forget what you read. It's configurable but not automatic. You can use ANY subnet plan EXCEPT the one that is used on the other nic. Your 10.x.x.x. should be fine.
