Problem between Utopia bootdisc & Performance VGA adapter

Has anybody encountered this problem?

Utopia bootdiscs do not work with Performance VGA adapter, I got a message says the game doesn't support the AV cable when I boot up with either 1.1 or 1.2 discs and with the adapter plugged in.

If anybody has a remedy for this or has any information regarding this please please post it up or email me...

Appreciate it.
