How to make kernel recognize 4GB of RAM
by Claudio Miranda
Hi, How to make the kernel recognizes 4 GB of RAM memory ?
It is a Lenovo T400 Laptop.
Fedora 12
2.6.32.11-99.fc12.i686 #1 SMP Mon Apr 5 16:32:08 EDT 2010 i686 i686
i386 GNU/Linux
$ head -1 /proc/meminfo
MemTotal: 3057360 kB
dmesg shows
total RAM covered: 3998M
The BIOS shows 4 GB of RAM memory
Looks like the kernel initially recognizes the 4 GB, but is unable to
use it, is that right ?
I read elsewhere that if there are more than 4 GB of RAM, the
kernel-pae is necessary, but my laptop doesn't have more than 4 GB.
So, is it possible to have the kernel recognizes the 4 GB ? With or
without the kernel-pae ?
Thanks

Power management on a Macbook Pro
by john maclean
I have 15" MBP and it's all gravy. No matter how much I try to get used
to this OS I still yearn for a "proper *nix system" and put F12 onto a
partition on this laptop. So I'm dual booting with Snow Leopard and f12
and cannot help wondering why the power management is so different
between the two systems.
1 - OS X. Boot up and mouse over on the power icon. Tells me that I have
3.x hours of battery life remaining.
2 - F12. Boot up and mouse over on the power icon. Tells me that I have
1.x hours of battery power remaining.
How/why could these stats be so different? Is there any way to find out
myself? I know that OS X does not have a /proc/ dir so I will not be
able to compare /proc/APCI/blah/de/blah.
How do others find using F12/F13 beta with an MBP?

such as the macbook pro?
