Progress in understanding the issue but no solution -
after proper install of kernel 2.6.22 and initrd, the kernel cannot find /dev/root.
googled that for some reason the new libata calls sdx hdx - okay
I did:
edit lilo to append to the .22 entry root=/dev/hda4
now, the system booted, but since the kernel saw the dev as hda, dma was enabled, and so on, meaning that the hdd was slow, as in langsam or noch langsamer.
cat /proc/scsi/scsi revealed only the dvd device was scsi.
Now, I need to have the kernel direct read my sata drive - as in my mission critical grml, d h
