Just my bit of knowledge. When VESA 1.2 was around that was when manufacturers (
i guess ) started implementing support for linear buffers.
So while VESA had no software support for it ( or very little ) the hardware
was capable of this. My windows 3.1 driver for the Trident 9400 was doing
this and virtual screen (too bad I cant get a Win95 driver that does this.)
Anyone out there have a Trident 9400 with 2 Megs and can tell me what chips
to populate the second Meg with?
