Thanks for the tip. I'll check for Direct Framebuffer in the BIOS. What is MTRR? I catted /proc/mtrr and see the entries below but have no idea what they mean. [EMAIL PROTECTED]:~$ cat /proc/mtrr reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1 reg01: base=0x20000000 ( 512MB), size= 256MB: write-back, count=1 reg02: base=0x30000000 ( 768MB), size= 128MB: write-back, count=1 reg03: base=0xa0000000 (2560MB), size= 128MB: write-combining, count=1 [EMAIL PROTECTED]:~$ Thanks. _______________________________________________ openchrome-users mailing list [email protected] http://wiki.openchrome.org/mailman/listinfo/openchrome-users Main page: http://www.openchrome.org Wiki: http://wiki.openchrome.org User Forum: http://wiki.openchrome.org/tikiwiki/tiki-view_forum.php?forumId=1
