Hi,

I have recently bought a VGA card and use it with the XT bridge board.
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 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.
