Crystal clear!<br>thank youuuu..!!<br><br>Though another Q if possible..<br><br>i've done the following:<br><br>yum install kernel-pae<br><br>vim /etc/grub.conf<br>#outputs the following:<br><br># grub.conf generated by anaconda<br>#<br># Note that you do not have to rerun grub after making changes to this file<br># NOTICE: You have a /boot partition.
