Dealing with PAE

New to me. Good post and links.

In the CF-18, CF-19 line which "mark"/processor/version crosses the PAE barrier?

[kode-niner]

Well in the CF-19 line the MK1 is the only 32 bit processor, and I'm quite sure that the Core Duo U2400 doesn't have PAE flag issues.

When given a choice of a Linux Flavour iso that is "non-PAE" or "PAE" on an older toughbook, what's the best way to decide which one to use before burning and trying it out?

[SHEEPMAN!]

I did some reading this a.m.

How about installing a LiveCD in the older machine and

Code: Select all

cat /proc/cpuinfo

Look for the PAE flag. It sounds like some PAE capable machines will do PAE but do not show the flag. For our purposes if it shows no PAE under the flag section I would use the non-PAE OS. Sort out the odd-balls later.

I have loaded PAE in CF-29MK4/5 and then used it in non-PAE MK1 but it's a little slow. MK1 would be happier with a less sophisticated system.

Thanks! I did the unthinkable: Re-installed over a perfectly working CF-28MK3 using Navigatrix 0.4 with a non-PAE Debian system. Loaded but then did NOT work. Then Nav0.4 would NOT load either. Now it's working fine with Mint9XFCE, whew! No more testing on the CF-28 until I get another caddy to play with. On another note, I found this from the Debian site:
https://www.debian.org/CD/live/
Live install images
A “live install” image contains a Debian system that can boot without modifying any files on the hard drive and also allows installation of Debian from the contents of the image.
Is a live image suitable for me? Here are some things to consider that will help you decide.
•Launcher: In addition to text and GUI install options in the boot menu, the desktop flavors contain a launcher on the desktop that can be used to install while running the live image.
•Flavors: The live images come in "flavors", four providing the desktop environments GNOME, KDE, LXDE and Xfce, and two text console flavors: rescue and standard. Many users will find these initial package selections suitable, installing any additional packages they need from the network afterwards.
•Architecture: Only images for the two most popular architectures, 32-bit PC (i386) and 64-bit PC (amd64), are currently provided.
•Size: Each image is much smaller than the full set of CD/DVD images, but larger than the network install media. If you are installing from optical media, the standard and rescue images will fit on a CD, whereas the others require a DVD. If you are installing from a USB key, only LXDE, Xfce, standard and rescue will fit on a 1G device, whereas the others require a larger key.
•Languages: The images do not contain a complete set of language support packages. If you need input methods, fonts and supplemental language packages for your language, you'll need to install these afterwards.
More to follow -:)

I may have a caddy.

I checked in Device Manager and the PAE kernal was not being loaded. I ran

Code: Select all

cat /proc/cpuinfo

and the pae flag was there, so I loaded the PAE enabled kernal from Device Manager and rebooted.
The unit seems a bit quicker loading programs and web pages.
Thanks for the information.

Then again you don't need the live install if you're intent on installing Debian either way. All the non-live install flavors fit on a CD:
http://cdimage.debian.org/debian-cd/7.6.0/i386/iso-cd/
http://cdimage.debian.org/debian-cd/7.6.0/amd64/iso-cd/

Can you elaborate on what didn't work with the non-PAE Debian system?

Trying to understand "flags" as mentioned above.
