I'm not sure all these links are still good, but there is some public info about the atombios. The AtomBIOS disassembler is available at : http://cgit.freedesktop.org/~mhopf/AtomDis/ Matthias' blog post with instructions is at : http://emmes.livejournal.com/3678.html The most current atombios.h file version is usually the one in the kernel driver maintainer's drm-radeon-testing tree, which is at : http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=tree;f=drivers/gpu/drm/radeon;h=6630bf487791774dce32f62bc4c34516363ed7a4;hb=refs/heads/drm-radeon-testing > >> Thanks, >> >> Wolfgang >> >> >> >> _______________________________________________ >> SeaBIOS mailing list >> [email protected] >> http://www.seabios.org/mailman/listinfo/seabios > > _______________________________________________ > SeaBIOS mailing list > [email protected] > http://www.seabios.org/mailman/listinfo/seabios > -- http://se-eng.com _______________________________________________ SeaBIOS mailing list [email protected] http://www.seabios.org/mailman/listinfo/seabios
