Forcepae for future releases?

[chrispop99]

I've just been testing Linux Mint 17 Xfce 32 RC. You can append 'forcepae' to the boot arguments to allow the non-pae disk to boot on older machines where pae support is not available. I just tried it on an IBM Thinkpad T23, with a P3 CPU, and it worked fine.

Is this something that could be done in future versions of MX-xx, or would it be an issue with the CD space constraints?

It is a kernel patch. As long as we are rolling our own kernels (and there aren't any conflicts) then we should be able to include this feature without taking up any extra space. If we are using a kernel made elsewhere then we are reliant on them to include the patch.

Doesn't the non-pae MX-14 disk already boot on a machine where pae support is not available, even without the 'forcepae' option?

Yes, that sounds backwards--it's probably having the pae disk boot on a non-pae machine.

Yes, that's what he meant. Mint has one ISO. If it detects a proc that doesn't support pae OOTB, it tells you to use the 'forcepae' cheat to boot the live disk. I ran into that myself recently when I was just playing around with an old lappy and the new Mint Mate.

Doing this would mean there wouldn't have to be two ISOs offered and maintained.

That would certainly be worth testing.

The Debian backports kernel used in MX-14 doesn't have that forcepae patch it seems.

[Stevo]

From reading the patch headers here: http://marc.info/?l=linux-kernel&m=139419246804442

it seems that the patch actually turn PAE back on for Pentium M chipsets on which Intel disabled the feature.

From the time frame, it seems it's for the 3.14 kernel.

It also appears it appears in the Ubuntu kernel for their 14.04 release. That's using the 3.13 kernel.

There is already reply, but I repeat it, too.

"forcepae" is boot option of Ubuntu (base) only.
MX-14 is Debian base, and there cannot be the thing that it is added soon.
There is "non-PAE version" in MX-14. It is not in this way necessary to mind "forcepae".

Keep it Simple. Whichever way is less work for the devs.
