What kind of issues ? Is it VGA BIOS,or driver issues. I'm surprised the your Cirrus Logic card is failing, they're one of the > better > documented card series. Maybe the code has just bitrotted. I checked this card in Windows . It works if it is taken as primary display. if it is taken as secondary then the driver initialization is failing. May be this card is old and may not work as secondary VGA. Just kidding !!!!! (Showing VGA BIOS 2005). I have checked linux cirrusfb driver and it is directly accessing the Legacy VGA Range. (drivers/video/cirrusfb.c) This implies to me that this card can never be supported as Secondary VGA with this linux driver.(I dont know how X Server act on it) Please correct me. Regards Rupesh
