The cd gives the error-

Could not mount disk to /mnt/system. Starting debugging shell.
sh: can't access tty; Job control turned off.

using knoppix debug -b 3; It stops on 0.247245 Simple boot flag at 0x3a set to 0x1

failsafe debug -b 3; [0.1532171] platform rtc_cmos: registered platform RTC device (no PNP device found)
I've tried the cheatcode; knoppix vga=0 and acpi=off, pnpbios=off.

What am I missing?
