  I'm trying to revive an older Lenovo.  It has worked in the past.
Here is the kernel panic error (3 lines)...

VFS: Cannot open device "801" or unknown-block (8,1): error -6
Please append a correct "root=" boot option: here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root on unknown-block (8,1)

  I've pulled in a working configuration from an old backup, so it
should work.  I'm also listing "fdisk -l", "ll /boot", and
/etc/lilo.conf  (the machine is too old for UEFI).  Any ideas?
