how did you "verify" that lilo wrote to the wrong disk
vs the scsi disk already having the mbr from prev installs
how do you know the "lilo stuff" you see on the screen is coming
from hda vs sda
- did you make the look-n-feel different on the different disks
so you know that the mbr you see on the lilo boot screen is
the one corresponding to each different disks
- label theboot kernel differently, explicitly for each
hard disk
- that is a trivial way to see which MBR is being booted
- it's NOT possible, or extreme slim chance, lilo writes to the wrong
boot=/dev/xxx divice

than you cannot claim there is abug if you cannot explicitly confirm it
and duplicate the error

not possible ... more likely that there;s something you forgot or
overlooked ... lilo does NOT write tothe wrong disk ... it does
NOT overwrite anything
- which version of lilo ...
- did you go to the lilo site to download the latest version
that was previously posted ...

bios boot order has NOTHING to do with "disk stanza" (presumably in lilo)
