Hi all

I am having a difficulty to pxe boot a KNOPPIX from Solaris grub.
I downloaded knoppix 6.2 and configured all , the client machine try to pxe boot but goes to shell with the following error:

14 914951 cloop disagrees about version of symbol module_layout
insmod: error inserting '/mnt-system/KNOPPIX/modules/cloop.ko': -1 Invalid module format." : Exec format error

couldnot mount /mnt-system/KNOPPIX/KNOPPIX

Any help appreciated.
