Well, I have a setup where NT stays on my 1st HD and linux on the 2nd
hard disk.
(both are 540 MB hds).

What I essentially did is the reverse thing with respect to
what you are trying to do.
I had LILO take over the MBR on the Windows NT disk (no problem to NT),
and with Lilo I can fire off NTLDR. From what I understood it seems that
NTLDR stays on the disc partition, not on the MBR (good thing for LILO
to manage!).

In case you are interested, here is my lilo.conf

# Boots Linux and NT from LILO
#
# Start LILO global section
boot = /dev/hda
install=/boot/boot.b
#compact # faster, but won't work on all systems.
prompt
vga = normal # force sane state
ramdisk = 0 # paranoia setting
# End LILO global section
image = /vmlinuz.1.3.98
root = /dev/hdb1
label = Linux1.3.98
read-only # Non-UMSDOS filesystems should be mounted read-only for
checking
image = /vmlinuz.1.3.97
root = /dev/hdb1
label = Linux1.3.97
read-only # Non-UMSDOS filesystems should be mounted read-only for
checking
image = /vmlinuz.1.2
root = /dev/hdb1
label = Linux1.2
append = "sbpcd=0x230,SoundBlaster"
read-only # Non-UMSDOS filesystems should be mounted read-only for
checking
image = /vmlinuz
root = /dev/hdb1
label = Precompiled
read-only # Non-UMSDOS filesystems should be mounted read-only for
checking
other = /dev/hda1
label = NT
table = /dev/hda

When I choose NT from LILO, the NTLDR comes immediately out.

And, of course, you can have it as your default. In this way no LILO
diskette is
necessary.

Hope this helps!

Ciao, Paolo
