I was installing RH 5.2 on a dual-boot system with a Western
Digital Hard Drive that needs it's own proprietary drivers
loaded at start-up (the drive is only used under Windows).

When I got to the step in installation to determine the
method of booting (where would you like LILO?), I chose
'Skip' (I already made my boot floppy).  It still managed to
overwrite the master boot record, so I had to rewrite the
MBR with the western digital junk.

Not a big deal for me, but I know there are plenty that
would have been dead in the water at that point.

Otherwise, wow!  Linux that can talk to my printer & sound
card!  I love it!  (Maybe I can convince my wife we don't
need the Windows boot!)
