passing forcepae option to *buntu fails

#1 Post by LeSanglier » Mon Mar 16, 2015 4:01 am

Hello UBCD-community,

first: thanks for UBCD & this forum!
I'm using UBCD for many years now and I 'm really grateful for you guys doing this. This is the first time I've come across something I can't sort out myself. Here it is:

I'm using UBCD 5.33 on a Debian-pure-blend-mostly-based-on-wheezy-OS (therefore changed from mkisofs to genisoimage), currently trying to create a multiboot DVD with several *buntu-Versions. All other OSs are standard stuff and work fine. The forcepae-Version of Xubuntu looks like that:

Code: Select all

MENU LABEL Xubuntu 14.04.2 LTS live
 Xubuntu LiveOS
LINUX /xubuntu/vmlinuz
INITRD /xubuntu/initrd.lz 
APPEND file=/cdrom/preseed/xubuntu.seed boot=casper iso-scan/filename=/xubuntu/xubuntu-14.04.2-desktop-i386.iso quiet splash forcepae -- forcepae 
// ubcd/menus/syslinux/main.cfg

...and does not work.
The forcepae option seems to be completely ignored. Any ideas? It's probably just a minor issue but I'd really appreciate help with this one.

Stupid me! This does (probably) work. Explanation:

"Many Pentium M systems disable PAE but may have a functionally usable PAE
implementation. This adds the "forcepae" parameter which bypasses the boot
check for PAE, and sets the CPU as being PAE capable..."

found here: ... 03075.html

Just when I switch off pae/nx on the virtual machine it is indeed switched off.

however, thanks for reading, keep going guys!
