Re: Boot linux from two linux partition

Sorry for this silly question. I am new to both Debian
and Linux.
My disk has following partions:
/dev/hda1 DOS
/dev/hda2 extended partion
/dev/hda3 swap
/dev/hda4 Red Hat linux
/dev/hda5 Debian 1.3
By installing debian, my computer starts from /dev/hda2
and boot /dev/hda5. Can someone tell me how to setup
lilo so that I can also /dev/hda4 ? I know there are doc
about it, but I can not find them. :( Here is /etc/lilo.conf
-------------------------
boot=/dev/hda2
root=/dev/hda5
compact
install=/boot/boot.b
map=/boot/map
vga=normal
image=/vmlinuz
label="Debian Linux"
read-only
other=/dev/hda1
label="Windows 95"

Hmmm. I'm not exactly new to Linux, though I feel like it sometimes, and I had
trouble with almost this exact problem. I was trying to do Debian 1.2 and
Debian 1.3 rather than Red Hat and Debian 1.3, and I was using separate
physical drives, but I think the problem is the same. The only solution I've
found (I would be *very* happy to hear from someone who had a better solution)
was to install LILO twice. The first copy of LILO is almost exactly the same
as your setup above, with the addition of
other=/dev/hda4
label="Red Hat Linux"
loader=/boot/chain.b
The second copy of LILO is installed in the boot block of /dev/hda4 (NOT in the
MBR), and just boots by default into whatever setup that copy of Linux uses.
Since I experiment with new kernel versions from time to time (part of the
hazards of owning a dual processor machine), I also like to keep two kernel
versions available in /etc/lilo.conf, so that there is always an old, working
kernel available, no matter what sort of disaster^H^H^H^H^H^H^H^H jdevelopment
kernel I try. That complicates the scenario, but not by much (just an
additional entry in each lilo.conf).
email if you'd like copies of my two lilo.conf files.
