kernel panic when booting knoppix

I am getting this error when trying to boot knoppix.

kernel panic-not syncing:VFS:Unable to mount root fs on unknown-block (1,3)

I tried burning a disk at 1x speed, but am still having the same problem. Does anyone have any ideas on how to fix this?

Thanks for your help

It sounds like knoppix is unable to mount the root file system.

Since the initial root file system is a ramdisk, I am going to assume that you are having problems with your ram disk creation.

Maybe it will help if you specify the size of your computer's installed RAM.

At the boot prompt, type:

knoppix mem=512M

where "512" is the number of Megabytes of installed RAM on your system. 1GB of ram is equal to 1024 Megabytes.

Don't forget to use lowercase letters for "mem" and an uppercase letter for the "M" after the 512

Good Luck.
