I just bought an IBM/AT clone with a Paradise VGA card. (I beleive 
it is PVGA-16.) The card clearly has the maximum 512K (I see the 
chips), but all of my program says, that it has only 256K. I 
checked that the jumper, which selects the memory size, is setted 
correctly, so now I don't know what's the problem.
I have the suspicion that the video memory start address is 
setted incorrectly. Norton 5.0 Sysinfo says that it starts at 
0xB800, however the card's manual says it should start at 0xA000.
Is this really a possible problem? 
If yes, how can I change it in the CMOS? I have AMI BIOS '89, but 
the setup system doesn't support the change of the video memory 
start address. Is there any program which can do this? 
If not, what do you think, what can be the problem?

I hope somebody can answer my question.

Thanks in advance.
