Hi (...again for those who read comp.sys.amiga),

I have recently bought a VGA card and use it with the XT BridgeBoard.
It works OK in EGA, CGA and other modes but I have some problems with
high resolution VGA graphics modes - the PC screen freezes and I cannot
access my hard disc card from amiga side anymore. I think that maybe
the video memory (512KB on the VGA card) addresses collide with Janus 
dual port memory but I have no documentation on that.

Can some jumpers on the bridge change that address ?
What the RAM address option in the pc-prefs is for ? (when I change the
default address and reboot the amiga cannot do a djmount...)

All hints welcome.

Thanks.

  Jarek Baryeka.
