Knoppix 6 with boot code "knoppix" boots to a black screen, empty but for a movable mouse cursor, on my old desktop that has worked fine with the last few Knoppix versions. ctl-alt-backspace resulted in the brief appearance of some log files, then automatic shutdown.

The md5sum for the boot disk (after burning) is correct.

You have to be fast to enter the boot code in the short interval provided, and on my display the first three characters of the "boot:" prompt are offscreen. A new user might not get past this point.

A method to change the default boot code that depends on booting from USB does not help those of us with a BIOS that is not capable of booting from USB.

I realize 6.0 is essentially a beta version. This is a report, not a complaint. 5.3.1 works fine.
