Yup.  Byte 446 starts the primary partitions.

But usually one would run some sort of bootloader command immediately
after which would have restored the MBR.  My guess is that you
rebooted instead.  This is why it's a good idea to back up your MBR
before making changes to it.

I'm curious why you just didn't set up grub to boot xandros since it
was already working.  I had no idea anyone still used lilo.

As for "Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(3,1) " I think you could have run rdev to tell the
kernel where root was.
