No, the "traget" is no problem for me, since SoftICE freezes as soon as it would normally show its window. This means when I start SoftICE, it normally pops up for something like 0.3 seconds to execute the "INIT" commands and return to Windows. But my computer simply freezes (no BSOD or similar) when I start it.

And if I'm running a SLI configuration than it's unlikely that I have a GeForce4 Ti 4200, right?
