bootloader setup

Hi people,

I've compiled a new kernel (I need IP forwarding) and then
I want to boot it. 
I've read about mkbootimage and I want to be sure about
what I'm going to do, 
so I don't have to reinstall from zero again.

I've created  a boot image.

/usr/mdec/mkbootimage -b /usr/mdec/boot_com0 -k /netbsd -s
boot.fs


Now, what's the next step? Should I dd it to /dev/sd0? 



Thanks in advance,

Pilla

Your disklabel should have a "boot" partition,
like so:

#        size    offset     fstype [fsize bsize cpg/sgs]
 a:   8540700      9863     4.2BSD   2048 16384 27304  #
(Cyl.      9*-   8143*)
 b:    263307   8550563       swap                     #
(Cyl.   8143*-   8394*)
 c:   8813870         0     unused      0     0        #
(Cyl.      0 -   8394*)
 e:      9800        63       boot                     #
(Cyl.      0*-      9*)

So, in my case, I would:
dd if=boot.fs of=/dev/rsd0e bs=512 conv=sync

Allways write the new kernel to the boot partition.  Don't
put it anywhere
else.

You should be able to enable IP forwarding with
sysctl -w net.inet.ip.forwarding=1
on a GENERIC kernel at runtime.

You can edit /etc/sysctl.conf to enable it at boottime.

Good thing I asked before exploding my disk! 
Rebooted with the new kernel 
and it's working.

Yes, I had it on but I did a mistake on the ipnat.conf file
(which I fixed 
now), so it wouldn't work and thus I blamed the kernel.

I'm more used to Linux, thus I still have a lot of things
to learn on netbsd.

Thanks,

Pilla

Yeah.. I'd really like to put together a FAQ for prep, I
just haven't had the
time yet.
