I am running ver 4.0.2 on a PIII 1GHz machine. I am not able to have my persistent image detected on startup. I am using a 80GB USB HD with 6 total partitions on it. The image file gets created on logical partition /mnt/sda7 (ext2) without error. I create a few files in the /home/knoppix folder to verify that I am able to write to the partition after the image is created. Now after I restart, the contents of my /home gets blown away with none of my files present. During the boot process, I get no prompt asking me if the persistent image file found should be loaded like the wiki stated. I also read somewhere that during bootup, I should see a message to the effect of "Mounting /mnt/sda7/knoppix.img as /home/.... I have never seen this message. I have also tried the following cheatcodes without success:

knoppix home=/dev/sda7
knoppix home=/mnt/sda7
knoppix home=scan

So what am I missing?

Everything that I have read about the persistent image says it should just work.
