I'm looking for code in assembler (GNAT/DJGPP format) to 1) Draw a line in a memory area (linear addressing, 1 byte per pixel) 2) Copy a buffer from a memory area to VESA video memory with VESA 1.2 bank switching or using VESA 2.0 frame buffer ( Is it faster when 2.0 is emulated ? How to get the address of frame buffer ? ) 3) Swap the display between 2 video memory areas without moving images ( Is it possible ? Is there a reliable method to determine whether swapping is supported and has enough video memory ? ) Thanks in advance for bits of information or useful URL's ! -- Gautier -------- Homepage: http://www.unine.ch/math/Personnel/Assistants/Gautier/Montmollin.html Software: http://www.unine.ch/math/Personnel/Assistants/Gautier/Gaut_FTP.htm
