--- Comment #4 from j.fikar@gmail.com 2012-03-14 14:46:30 --- for 256MB, 512MB and 1024MB I get
[ 6.301475] [drm] CONFIG_MEMSIZE: 0xffffffff
also I need a cold restart when changing UMA size in bios, otherwise it's not changed.
so is it a bios problem? should I try to complain to Asus? Is there an easy workaround? Like using manually vramlimit?
