We used Unetbootin to write a Xubuntu 16.04 .ISO file to a 16 GB USB memstick to make a live system. When we start the live system the error appears...
“WARNING: PAE disabled. Use parameter ‘forcepae’ to enable at your own risk! (...) This kernel requires the following features not present on the CPU: pae.” Almost all solutions suggest selecting Advanced Options or F6 on the menu but we found neither menu option shown; instead our boot menu screen shows... * Default * Help * Try Xubuntu without installing * Install Xubuntu * Check disc for defects * Test memory * Boot from first hard disk Sysinfo tells us we have a Pentium(R) M processor (as in the Bug description) so is suitable to use forcepae as other solutions say. Although not listed in our boot menu we found we could cheat and press F6 then Tab to get a command line that could be appended to. However we would prefer a menu system that worked especially if the 'live memstick' is to be used more than once. A solution is to mount the 'live memstick' into a working Xubuntu system and edit it, for example... sudo mousepad extlinux.conf For every line starting "append initrd=" append " forcepae -- forcepae" An example for menu option "Try Xubuntu without installing": BEFORE: append initrd=/casper/initrd.lz file=/cdrom/preseed/xubuntu.seed boot=casper quiet splash --- persistent AFTER: append initrd=/casper/initrd.lz file=/cdrom/preseed/xubuntu.seed boot=casper quiet splash --- persistent forcepae -- forcepae Booting from the edited live USB memstick showed the PAE error replaced by an advisory that the PAE test is being bypassed and normal menu operation takes place. Asides: * The result of choosing Default in the above boot menu is not described however we can see the 'command line' this option is associated with in extlinux.conf and note it does not re-appear in any of the other options presented. * The command line that appears under 'the cheat' above has an unknown action. * Although our command line included "--- persistent" and a file of expected size named casper-rw is generated we have yet to see signs that this Unetbootin feature is working. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1586748 Title: Lubuntu 16.04 does not install on a non-pae processor Status in linux package in Ubuntu: Invalid Bug description: I have Acer Aspire 1410 notebook with Pentium M processor.I tried to install Lubuntu 16.04. When I used forcepae option two times in boot menu options installation begin. After a while installation stops always to: [drm:intel_set_cpu_fifo_underrun_reporting[i915] Error Pipe A unknown] And acerhdf unknown.
