1. The Problem -- The new lilo won't overwrite the old boot sector.

Lilo question --

Summary --

The Problem -- The new lilo won't overwrite the old boot sector.

First boot sector has a pre-21 LILO signature

Details --

I ran redhat 4.2 on a dual ppro for years.
The boot scheme was a small dos drive as /dev/hda (mounted as /dosc),
a CD as /dev/hdb, and the linux drive as /dev/hdc.  The boot
stuff was on /dosc.  

I added a new drive /dev/hdd and put linux 6.0 on it.  I used LILO under 4.2
to add the new rh6.0 kernel.  This works, but is a) inconvenient, and
b) I can't get my home-made kernel to boot.  I want to solve a).

Here's some of lilo.conf
===========
# Start LILO global section
boot=/dev/hda
install=/dosc/linboot/boot.b
map=/dosc/linboot/map
# 990627 try to add the smp kernel.
#compact        # faster, but won't work on all systems.
delay = 300
vga = normal    # force sane state
ramdisk = 0     # paranoia setting
# End LILO global section
# Linux bootable partition config begins
# Rearrange 971228
# Rearrange 971229 -- replace hdb with hdd, add hdd=chs lines, delete
# all refrences to hdc.
# Sat Oct 16 05:26:49 EDT 1999 use old lilo to get around
# "pre 21 signature problem".  Add smp22120
#
# End LILO global section
# Linux bootable partition config begins

# here's the old 4.2 kernel, with the old /root
image = /dosc/linboot/lin2034
  label=pprosmp
  append="ether=eth0,7,0x280  hdc=638,255,63  hda=989,12,35"
  root = /dev/hdc3

# the uniprocessor rh6.0 with the new /root
image = /dosc/linboot/lin22515
  label=rh6.0
  append="ether=eth0,7,0x280  hdc=638,255,63  hda=989,12,35"
  root = /dev/hdd1

# the distributed SMP kernel from 6.0
image = /dosc/linboot/smp22515
  label=rh6smp
  append="ether=eth0,7,0x280  hdc=638,255,63  hda=989,12,35"
  root = /dev/hdd1

# my home-built kernel
image = /dosc/linboot/smp22120
  label=smp22120
  append="ether=eth0,7,0x280  hdc=638,255,63  hda=989,12,35"
  root = /dev/hdd1

I've tried lilo -u under 4.2 and 6.0, and dos fdisk/r.
