toRAM simply copies the entire KNOPPIX file
(695MB) to a RAMDISK.

then what's left will be your system memory.

so 768MB is not that much RAM. still no explanation to as why it
would not load for you.

for DVDs, use the FROMDVD option to only copy files from the Knoppix directory to ramdisk, and not the entire DVD
(you'll run out of space on the ramdisk then..)
