I'm a newbie with knoppix, so I think I cannot yet help others. I can boot from a
v3.4 CD-ROM when I use an old-fashioned, read-only Compact-Disc reader device.
Then all is OK.

But when I try to boot from a CD-RW Mitsumi CR487-ETE, the boot sequence
ends with a message: " Knoppix File system not found. Sorry! " I'm using the same
disc (v3.4) in each case. The CD-RW read-write device is correctly recognized
during boot as hdd:

After the "not found" message, Knoppix puts me into a very limited shell.
Can I somehow command
1) the KNOPPIX filesystem to be mounted from device hdd,
and
2) the knoppix/KDE to continue initialization ?
