lenovo b50-80 laptop i3-5010u/broadwell(hd5500)/4gb ram
on various x86 distros i have ~2.4gb ram usable (antix,slitaz)
on x86_64 distros i have ~3.8gb ram usable (antix,manjaro)
this happens on live boot as well as on installed distro
i suspect it must be somewhow related to the integrated gpu hd5500 but cant figure it out
never encountered this before, i have no idea where to start
ive been wondering for almost 24 hours, please help
no offense, but i dont think thats the problem
on other machines, same distro i see over 3.5gb ram without pae
even on windows xp i saw 3.2-3.8 from 4gb depending on machine
but not 2.4gb, i cant believe this
