Hi all,
I have 4 Go Ram but I can only see 3, in the BIOS I can see 4096 Ram...
I have the Ubunto 12.10 32 bits and I have read the following:
You misunderstand PAE. It allows you to access more REAL RAM (on the motherboard). The 32-bit address space remains at 4 Gig - of which (usually) 1 Gig is kernel reserved."
If Correct how I can see if how much RAM is reserved for de Kernel, and hence is normal to see only 3Go RAM?
Another problem....
After this:
sudo apt-get install linux-generic-pae linux-headers-generic-pae sudo apt-get remove linux-generic linux-image-generic linux-headers-generic
and
dpkg -l | grep linux-image
ii linux-image-3.5.0-17-generic 3.5.0-17.28 i386 Linux kernel image for version 3.5.0 on 32 bit x86 SMP
ii linux-image-3.5.0-19-generic 3.5.0-19.30 i386 Linux kernel image for version 3.5.0 on 32 bit x86 SMP

well ok.... I Have found the following:
For permanent change you'll need to edit your /etc/default/grub file -- place a "#" symbol at the start of line GRUB_HIDDEN_TIMEOUT=0.
Save changes and run sudo update-grub to apply changes.
But nothing appears....
I know that my processor is compatible with PAE because:
I have run a script and this the result

Upgrade to the 32-bit kernel with PAE 'linux-generic-pae' to get access to more memory

Thanks for any suggestion!
Best regards.
