I use RH7.0 with all the latest patches on an AMD475 processor. The same thing works great under RH6.2 whenever I issue the following command: mount -t iso9660 -o ro,loop=/dev/loop0 7.0-i386-upgrade.iso /mnt/loop/ I get this output: ioctl: LOOP_SET_FD: Invalid argument Thank you in advance for your help Vince
Can't reproduce this... Maybe your loop0 device is already in use? Try letting the kernel choose: mount -tiso9660 -oro 7.0-i386-upgrade.iso /mnt/loop
