unless you have more than one sat lnb and are running them all through a diseqc switch to your box via a single cable then you can leave setting as it is, this should make it all clear as mud for you

DiSEqC = Digital Satellite Equipment Control, this was designed for FTA receivers.
DiSEqC switches come in 2 main flavors, Committed(1.0) and Uncommitted(1.1),
but also Committed 2-way(2.0) and UnCommitted 2-way(2.1).
Committed(1.0) switches are the most common and are what come with the receivers.
These switches require FACTORY software in your FTA to operate properly,
1.0 means your receiver can operate Committed switches ONLY,
1.1 means it can operate Committed AND UnCommitted switches,
1.2 means it can operate Committed and UnCommitted plus DiSEqC motor controls.
2.0 is the same as above,
2.0, 2.1, 2.2 but the receiver can also receive information back from the switch,
2.0 switches receive the pulse command from the receiver, then change ports,
they then send back a confirmation to the receiver, if a 2.0 receiver doesn't
receive the confirmation it will send the DiSEqC pulse again and again until the
switch confirms it is on the right port.
Putting 2 DiSEqC Committed switches on one cable is a no-no, which is why there are
Committed and UnCommitted types of switches, a Committed switch is placed first in
line (DiSEqC pulse comes from the receiver so first would be closest to the receiver),
then you can hookup an UnCommitted switch to the Committed switch, the Committed switch
will ignore the UnCommitted switches commands.
Committed 4x1 switches are about half price of UnCommitted 4x1 switches, so unless
you have to have 16 LNBs hooked up to one receiver stick with Committed switches.

Nice one, thanks, LraiZer- that explains that one perfectly. So it's an option for the experts, then? I'll leave well alone, LOL!

Back to head.ko now... The vital bit for the first time boot on a newly-compiled dm500 image appears to start here, at line #46 in the rcS of C12:

 
# check if /var/.init exist .. then no flash erase is needed .. this is new !
if [ ! -e /var/.init ]; then
# new /var/.init not found.. check if old /var/tmp/init exist.. 
# then not flash erase ist needed
    if [ -e /var/tmp/init ]; then
# ok old /var/tmp/init exist.. no create the new flash_erase detection file..
 touch /var/.init
# delete /var/tmp folder now..  
 rm -rf /var/tmp
# create link to /tmp <- this is mounted to RAM 
 ln -sf /tmp /var/tmp
    else
# flash erase is needed ...     
 init=1
    fi
fi
if [ $init -eq 1 ] ; then 
 cp -a /var_init/* /var
 touch /var/.init
 sync
 umount /var
 /bin/mount -t jffs2 /dev/mtdblock/1 /var
fi

Is it safe to delay the external call to init1 (and the head.ko load) until AFTER this point, or would this be doomed to fail, on account of other init1 related stuff being present prior to line #46, do you think?

Yes it is
just changed this

    touch /var/.init
    sync
    umount /var
    /bin/mount -t jffs2 /dev/mtdblock/1 /var
fi

ln -sf sound/dsp /dev/dsp

To this

#!/bin/sh

/bin/mount -n -t proc proc /proc
/bin/mount -n -t devpts devpts /dev/pts
export INSMOD="/sbin/insmod"
export RMMOD="/sbin/rmmod"

    fi

# do not mount jffs2 when not booting from flash
if [ ! -e /root/platform/kernel/bild ] ; then
    mount -t jffs2 /dev/mtdblock/1 /var

/bin/mount -t ramfs none /tmp
# /var/run links here

# flash erase is needed ...     
    init=1
    fi
fi

if [ $init -eq 1 ] ; then 
    cp -a /var_init/* /var
    touch /var/.init
    sync
    umount /var
    /bin/mount -t jffs2 /dev/mtdblock/1 /var
fi
#export TZ=CET-1CEST,M3.5.0/2,M10.5.0/3
/etc/init.d/init1

#set environment variables ( mID )
. /proc/bus/dbox.sh



ln -sf sound/dsp /dev/dsp

so just moved the

#export TZ=CET-1CEST,M3.5.0/2,M10.5.0/3
/etc/init.d/init1

#set environment variables ( mID )
. /proc/bus/dbox.sh

to after all the jffs mounting crud.

box boots fine.
now it needs a test with a commando image and a different head.ko file.

Will still need in the init1 file

if [ -f /lib/modules/$(uname -r)/.reload_modules ] ; then
    $RMMOD $MODDIR/extra/head.ko
    $RMMOD /var/driver/head.ko
fi
if [ -e /var/driver/head.ko ] ; then
$INSMOD /var/driver/head.ko
else
$INSMOD $MODDIR/extra/head.ko
fi

pointless moving the existing head.ko file.

[PaphosAL]

Disagree about the pointlessness of moving the existing head.ko from $MODDIR/extra - you haven't thought this through fully.

We need the new one in /var_init/driver to copy to the new /var/driver when it's first created, don't we? So why have two in squashfs root, when one will suffice?

Your earlier fall-back code to load from /var_init/driver looked flawless to me...

You havn't thought it out Al
If you leave the original where it's supposedto be then space is where it was.
If you put it into /var_init/etc/driver then on 1st boot it will be put into /var/etc/driver taking space from the jffs which isn't needed as it exists in the squashfs area.
Only people needing a different one need to lose the space in /var or do I take it space is no longer an issue ?
If you leave it where it is then there is no need for one in /var/etc/driver or /var_init/etc/driver unless the user needs to use the space in /var then they just put one into /var/etc/driver which will take precedence over the one in /lib/modules/2.6.9/extra which is why I did this bit of code

if [ -f /lib/modules/$(uname -r)/.reload_modules ] ; then
    $RMMOD $MODDIR/extra/head.ko
    $RMMOD /var/driver/head.ko
fi
if [ -e /var/driver/head.ko ] ; then
$INSMOD /var/driver/head.ko
else
$INSMOD $MODDIR/extra/head.ko
fi

In the init1 file

I don't understand your obsession with space but I tailored it to keep you happy and your trying to throw away 300kb of it
