Try:

cat /boot/config-2.6.24-16-generic | grep CONFIG_EFS_FS

if it says:

CONFIG_EFS_FS=m

and

cat /boot/config-2.6.24-16-generic | grep CONFIG_SGI_PARTITION

says:

CONFIG_SGI_PARTITION=y

Then your system is able to mount efs disks. Use the following:

mount -t efs -o loop /dev/cdrom /cdrom

This works perfectly on Ubuntu. Change the /dev/cdrom to the appropriate according to your system.

Good luck, tschüss
