Install Wheezy on cpu non pae?

Postby TKZ911 » 2013-06-24 11:37

Hi all

I tried install Wheezy on laptop with cpu non-pae!

The message warning that cpu not pae, and fails install.

My question:

Is possible install Wheezy on cpu non-pae with kernel 686-non-pae? :(

Thanks :)

Regards :D

Try with linux-image-3.2.0-4-486

Description: Linux 3.2 for older PCs
The Linux kernel 3.2 and modules for use on PCs with a single processor not supporting PAE

With Squeeze I was kernel 686-non-pae, but if I want install Wheezy choice kernel 486!

Why will kernel 486 if with Squeeze I was kernel 686? :shock: :roll: : :)

All CPU are now supporting PAE.
Then, old/486 now means non-PAE !

My cpu is Intel Centrino Dothan 32bit.

Once upon a time there was a 686 kernel - it was dropped, so now users who had to use 686 now need the 486 kernel. (If you really want a 686 kernel you could build one.)

My memory is fuzzy on this (so I welcome correction/clarification), but the 486 kernel builds are for any CPU's which were not "pentium pro class" (P6 (Pentium Pro/II/III)), i.e. lacking the cmov instruction (e.g. the AMD K5/K6 CPUs and earlier P5 (original pentium) which are 586 class).

686 was for any CPU, pentium pro class and upwards, which does not support PAE/NX bit.

686-pae is for all newer 32 bit CPUs (or "amd64" (all modern intel/amd CPU's with the exception of IA64) CPUs if you still want to run a 32 bit kernel).

According to wikipedia, not all models of the Dothan support PAE/NX: https://en.wikipedia.org/wiki/List_of_I ... 2890_nm.29

A bad day at the Big Box stores, so here I am!

I dug out my 10 year old Gateway laptop which does contain a Centrino Pentium M Dothan processor.

I then proceeded to install 686 and 686-PAE kernels in addition to the already present 486.

All three work for me.

All my kernels are Towo's so maybe it's his magic.

Where did you find a Wheezy with kernel not-pae?

Thanks :)
