For the first time I tried to install Xubuntu 12.04 on my computer using the Grub4dos way. However, it stuck and showed "This kernel requires the following features not present on the CPU : PAE". I therefore checked my device and found that my CPU is Dothan, which is quite old and without PAE. So I wonder if I can solve the problem by choosing another kernel that does not require PAE. Thx 4 ur help.
Try the non-pae mini cd. It will boot into netboot, and download the needed files
This is a simple iso file for the kernel and the drivers. You just boot this as you would a normal iso, but it has a text based installer. You nearly just press enter all the time. You have to give once the username and then password. At partitioning you just select the the guided one (without LVM) and on the package selection you select Xubuntu desktop.
A few weeks ago I installed Ubuntu 12.04 Alpha 1 on a laptop which I'm pretty sure does not support PAE without any problems. I suspect this PAE requirement may be a mis-feature (bug) of the current Xubuntu installer.
Xubuntu 12.04 was using the PAE kernel - the newer builds have reverted to the non PAE kenel now.
