I have Dell OptiPlex GX620, intel Pentium 3.2 GHz 2MB L2 cache, 945G Chipset, 1 gig DDR2 Ram and 160 GB Sata hard drive.

When I try to boot Linux Knoppix 3.9, I get the error

"Kernel Panic: Unable to mount..." etc.

I tried setting the SATA drive to combination but even then it doesn't work although the same error doesn't show up.

Please help
