Re: [9fans] booting options for brand new installation

howdy,

i've installed plan9 on a separate partition of my hard drive alongside
debian linux.

i'm not 100% clear on what boot option is best for a setting like this.

i want to boot plan9 using grub.

if that's not doable, can anyone please suggest an alternative way of
doing it.

My /boot/grub/menu.lst includes these lines:

title       Plan 9
root        (hd0,1)
chainloader +1

and the corresponding partition has /386/pbslba as a boot block --
see format(8).

thanks for the tip, Richard, but i found that debian squeeze doesn't
have /boot/grub/menu.lst anymore.
i tried googling for instructions on how to add alternative systems to
grub2, but so far haven't found anything substantial;
the only thing i did try was i added this to /etc/grub.d/40_custom:
menuentry "Plan9 from Bell Labs" {
     insmod chain
     insmod fat16
     set root=(hd0,1)
     chainloader +1
}

then i ran update-grub as root and rebooted the system;

this time "Plan9 from Bell Labs" did appear in the grub menu; i selected
it and got an error: message: error: invalid signature

the right way of doing it isn't immediately obvious to me;

any input would be appreciated;

i found what the problem was...
my plan9 partition is /dev/sda3, so the following entry in the
/etc/grub.d/40_custom file should read:
menuentry "Plan9 from Bell Labs" {
     insmod chain
     insmod fat16
     set root=(hd0,3) #not set root=(hd0,1)
     chainloader +1
}
it should be followed by running update-grub and rebooting the system;

the instructions above are confirmed to have worked on my system;
