PAE
If a 32-bit Trisquel installation won't proceed because "PAE is disabled", it may be the case that your hardware is capable of using the newer technology even though it was shipped with it turned off. Note that this is less common than PAE simply being unavailable, in which case a special kernel must be used. Examples of computers where Forcing PAE works include the ThinkPad T42, which has a Pentium M processor.
Trisquel 6 and 7 support an option ("forcepae") to enable PAE on Pentium M CPUs (where it is disabled by default). To enable it:
Boot the 32-bit Trisquel installer (not the net installer, unfortunately)
"Choose your language" popup appears. Use the cursor keys and hit the Enter key to choose your language
Press F6, a grey menu will popup with some boot options
Press escape to close the window
You will now see a line that says:
Boot Options file=/cdrom/preseed/trisquel.seed boot=casper initrd=/casper/initrd.lz quiet splash --
Edit this line and add the forcepae parameter with spaces twice around the -- at the end:
Boot Options file=/cdrom/preseed/trisquel.seed boot=casper initrd=/casper/initrd.lz quiet splash forcepae -- forcepae
forcepae -- forcepae note:
forcepae is required twice because it sets the boot parameters for two different kernel boots - the kernel that runs as part of the installer (left of --), and the kernel that runs on the installed system (right of --).
The text at the end should be -- forcepae not --forcepae. There is a space between -- and forcepae
Hit the Enter key, hopefully Trisquel will boot and the rest of your install will be successful.
