how to use or enable PAE in 13.37 32bit?
 

hey
i dont know anything about PAE except that using it kernel can use more than 3gb ram in a 32bit system. but my slackware 13.37 32bit just tells that i have 2.9gb ram(but i have 4gb). so what should i do? or is it correct?

check the kernel .config

you need the above

It's not as easy as adding those options to the configuration... You need to recompile your own kernel with the option posted above.

The kernel in /testing has PAE enabled:

oh no! That testing kernel!
I tried that one before, i totally ruined my slack!
Can you tell me how to install new kernel? I dont use mbr for my bootloader but i use windows bootloader and easy bcd... The last time i used that kernel, i had to boot using slack dvd, because bootloader did not work. Because of that, now i know more but a guidance is indeed needed... How to add new kernel to lilo?
So what to do?

Best tutorial ever.

Upgrading the kernel isn't that hard...

If you want to use the /testing kernel, install it with these options:

upgradepkg --install-new *.t?z

That will remove the old kernel and modules packages (and anything else not included) , and install the new one. Also make sure you run:

lilo

...afterwards (or whatever bootloader auto-configure you have) to reset the boot loader to the new kernel. Also, make sure you rebuild any packages you have that build kernel modules.

I think it's safer to use installpkg rather than upgradepkg

when something goes wrong with the new kernel, you can still boot to the old kernel

+1!

so i should use installpkg then run lilo, so what about having old kernel? Will it just add the new kernel or it will replace it in boot menu?

if you use installpkg, it will install a new kernel alongside with the old one, so you basically have to add a new entry on your /etc/lilo.conf to point to the new kernel

thx all the guyz, the problem is solved.
using new kernel, i now have full ram.
marking thread as SOLVED.
