Subject: Why does my VGA card stop my AT from booting from its hard disk?

I'm trying to get a Trident VGA card (16 bit 512K memory) to work with my
AT clone (12 MHz, 2MB memory, DTK bios).  The problem is whenever I put
the card in the machine and set the appropriate jumper to indicate "colour"
monitor the machine just won't boot from the hard disc.  It *will* boot from
a floppy though.

There are other problems too:  Sometimes the BIOS on the VGA card says it
has 256K memory and other times it says it has 512K memory.  Occasionally 
the screen goes blank and the machine hangs, and at other times all I 
see are vertical green lines.

Any advice you can give much appreciated,

Stuart
