Hi!
I have a Densitron mainboard with onboard video card.
It is a Chips controller with 2MB integrated video, and is set to 640x480 resolution.
The mainboard has 4 jumpers for 16 possible configurations for the LCD panel. However, the mainboard's BIOS table of available configs is filled with the same 640x480. Changing jumpers won't change anything on the LCD port.
Do you think it's possible to add some entries in the mainboard's LCD table?

Another question : is it possible to hack a VGA card's BIOS such that it would behave like a laptop's VGA adapter? I mean I want to set it's DVI port to a certain LCD panel's specs. Then make a DVI receiver card that will feed directly TTL inputs of a TFT flat panel.

Thank you!
