Boot error about PAE and will not boot. How to fix!

Post by bigpup »

This is usually on older computers that are not setup to or cannot use PAE.

Most Puppy versions have PAE enabled.

You can still use them, but you have to add an option to the boot loader entry.

Code: Select all

forcepae acpi=off

You can add it when you see the boot menu and select to edit.

Just as you see the boot menu with selections for booting.
Use arrow keys to move off of first entry. This stops auto selection of default entry.
You probably do need to use the first entry, so go back to it using the arrow keys.
When the entry is highlighted.

This is how to edit it and use the edit to boot.

Press e key on keyboard.

A screen will show the complete contents of the commands used by this entry.

To add the boot option
Navigate with the arrows keys of the keyboard to the end of the line that starts with linux. ...
At the end of the Linux line.
Add space and then forcepae acpi=off

Press Ctrl+X, F10, or Fn+F10 to start

Example edit for Bionicpup32 boot entry:
linux /vmlinuz pmedia=cd forcepae acpi=off
initrd /initrd.gz

If this works.
Booting from a Live CD will require you to do this each time you boot.
There is no way to edit the menu entry that is written to the CD. It is read only.

If it was booting from a Live USB install.
You could make a edit of what is on the USB in the boot menu config file. It is read/write.

The things you do not tell us, are usually the clue to fixing the problem.
When I was a kid, I wanted to be older.
This is not what I expected :o

I confirm @bigpup advice works.

My Dell laptop (model 8600 - year 2005) would not boot until the mod described below was added.
This laptop runs the Pentium-M CPU.

собака

собака --> это Русский --> a dog
"c" -- say "s" - as in "see" or "scent" or "sob".
