@David, I replaced all -pae packages. So, I guess I also got the kernel headers replaced. Recompressing the initrd can save some bytes and save me from changing isolinux conf.
I tested multiple squash options but the best was the one that is in wiki (https://help.ubuntu.com/community/LiveCDCustomization): sudo mksquashfs edit extract-cd/casper/filesystem.squashfs -b 1048576 The original ISO was very close to the 700MB CD limit. So, I tried hard to get, at least, the previous size. I tested in a vbox machine and, as the kernel was always nonpae, during and after the installation, it considered it good to go (even running on a pae machine). You can test this way. After that I tested in a real machine but if you got some problem, it might appear even in pae processors. BTW, bandwitdh limit of my dropbox is over again :-) It says it blocks for 3 days but it was back in less than that. Sorry, I'm a free dropbox user. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/930447 Title: Unable to Install Ubuntu 12.04 on Pentium M x86 Laptop due to PAE kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/930447/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
