Hi.
When you are writing to a portion of video memory that is =
completely at a different location of where the visual page is, does it =
still slow down the access time? For example, in mode 320x200x256, when =
you are write to Video Page # 0 and the visual page is also # 0, the =
transfer speed will be very SLOW. But if you are writing on Page #1 and =
the visual page is #0, does it still slow down? Thanks.

Probably not - but it would be highly dependent on the particulars of the
hardware on your video card.
