http://www.vesa.org As you can see, there are many VESA standards: http://en.wikipedia.org/wiki/VESA The one you are probably interested in is: http://en.wikipedia.org/wiki/VESA_BIOS_Extensions If you go to this page: http://www.vesa.org/Standards/summaries.htm you can click on the link in "Please click for a list of standards that are available in PDF format for immediate download". Just feed the form some garbage data -- you are going to use a standard dummy email address and password to get into the real download page. What you want there is probably vbe3.pdf. > I'm interested in 2D graphics rendering and thought about experimenting > with X server drivers (i'm familiar with X server internals). http://www.faqs.org/faqs/pc-hardware-faq/supervga-programming/ > Are PCs running linux still limited to doing all the video memory > accessing through one 64k window like vga? No! VESA introduced a protected mode interface a long time ago with VBE 2.0. That allowed pretty much any program to access a flat frame buffer on any machine as long as it used a DOS extender. This was back in the early nineties. Borland was one of the suppliers of easy programming environments that came with DOS extenders. VBE 3.0 has a protocol that gives applications access to the some of the acceleration functions that often were in the SVGA cards of the late nineties. I don't think it was ever widely implemented. -Peter _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
