LiLO doesn't need/use this real_root= convention. It knows that
/dev/sdb2 is /dev/sdb2. So, according to your fdisk and /etc/fstab output,
I think this /etc/lilo.conf should work for you:
[code]
# Faster, but won't work on all systems:
compact
# Should work for most systems, and does not have the sector limit:
lba32
# If lba32 does not work, use linear:
#linear
vga=773
# MBR to install LILO to:
boot = /dev/sda
map = /boot/.map
default = Windows
install = /boot/boot-menu.b # Note that for lilo-22.5.5 or later you
# do not need boot-{text,menu,bmp}.b in
# /boot, as they are linked into the lilo
