P.S.
I’m new in this forum, and even after reading all “HDD Install” section I’ve not found answer for my problem.

I’d like to add than copied to HD Knoppix-3.3 works good (with some restrictions as vmlinuz-2.4.22-xfs modules are not loaded) after booting in other kernels as from floppy or HD lilo, or by linld.exe, but vmlinuz-2.4.22-xfs led to “kernel panic, cannot mount root ...”

In HDD Install I met in lilo:

initrd=/boot/initrd.gz

What is this initrd.gz ?? Where to get it??

initrd=/miniroot.gz placed on HD from Knoppix CD led to the same result , i.e., Sorry, cannot find Knoppix.
