I'm trying to speed up some scrolling speed in Text mode 2 of the Geneve. Current code right now does a read of something like 24 x 80 lines, then does the standard scroll up. I know in Graphics mode, you can change the pointer by writing to a register and change the display position without the extra reading/writing. I have done that before and made some really FAST scrolling GIF graphics.
Is there something similar available in Text Mode 2? I know there are display pages, just wondering if I can change a pointer and "instant" scroll.
I know I can also tweek the VMBR and VMBW code to do repetitive reads/writes without looping as another option. Just trying to find the fastest way to scroll without thinking too hard this early in the morning. Up too late last night watching a ball game and brain is slow this morning.
