If your KNOPPIX CD makes strange noises during boot, or you see frequent errors like "cloop: read error", or programs on your KDE desktop keep crashing randomly, then your CD image is probably defective or incomplete, or your CD-burner created a defective CD due to wrong writing speed or bad media. This is the most common error reported. Please boot with "knoppix testcd" to check if the CD is OK, and/or even better, verify the MD5 checksums that are present on the mirrors before writing the CD. Also, please read the KNOPPIX-FAQ.
- In case of a failing hardware autodetection, try booting with any of the "no-" options as shown in the table above, like in knoppix noagp noddc noapm noapic nodma nopcmcia noscsi nousb to skip some critical parts of the autodetection system.
- The "noswap" option is useful for a forensic analysis without touching existing swap partitions.
- Some Boards apparently don't pass the proper memory size to the linux-kernel. It may cause the message "Panic: cannot mount root file system" and the system hangs. Use "knoppix mem=128M" to solve that problem if your system has 128MByte memory for example (caution: you MUST use a capital "M" here).
- Try "knoppix pci=irqmask=0x0e98" if (you have a notebook and) your PS/2 mouse doesn't work. (Possibly caused by a BIOS-flaw on your board.)
