Right ...

Done.
Now NX protection is active.

Thank you both for your input. 8^D

Best,

You can uninstall the non-pae kernel after you reboot into the new one.

I was fiddling with the install and ended up installing both.
Seems the metapackage is the best/most convenient option.

Should I uninstall the version specific package?
It's taking up space.

TIA,

Install linux-image-686-pae if you want the metapackage (so you get updated kernels with your regular package upgrades). Or else you could install linux-image--686-pae for a specific kernel.

Hello:

Today I put a spare HDD on my 1000HE to try and see how devuan_beowulf_3.0.0_i386 does there, hardware limitations and all.

Downloaded the netinstall *.iso here: https://files.devuan.org/devuan_beowulf/installer-iso/

groucho@eee-dev3:~$ uname -a
Linux eee-dev3 4.19.0-12-686 #1 SMP Debian 4.19.152-1 (2020-10-18) i686 GNU/Linux
groucho@eee-dev3:~$

A line in dmesg caught my attention:

[    0.000000] Notice: NX (Execute Disable) protection cannot be enabled: non-PAE kernel!

But the Intel Atom N280 inside is PAE able.

groucho@eee-dev3:~$ cat /proc/cpuinfo | grep flags | grep pae
flags		: fpu vme de pse tsc msr *pae* mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc arch_perfmon pebs bts cpuid aperfmperf pni dtes64 monitor ds_cpl est tm2 ssse3 xtpr pdcm movbe lahf_lm dtherm
groucho@eee-dev3:~$

It seems I may have installed the wrong kernel?
Can this get fixed without reinstalling?

TIA,
