First I upgraded qcontrol to get support for the TS[12]19:
	a) added the following line to /etc/apt/sources.list
		deb http://people.debian.org/~tbm/orion lenny main
	b) updated and upgraged
		image was also upgraded to 2.6.30-1
Second I created a new mtd2 as described later by Martin

Then created my backups of the current fs and the mtdblocks of the new
hardware TS219P.

The system seemed to boot normally, but I couldn't reach it on the
network.

I put the disks in the original hardware and took a look at dmesg.1.gz
and quickly saw what is going wrong:
	[42949385.390000] udev: renamed network interface eth0 to eth1

Searching /etc for instances of eth0 I found
/etc/udev/rules.d/70-persistent-net.rules containing two rules:

# Unknown net device (/class/net/eth0) (mv643xx_eth_port)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="yy:yy:yy:yy:yy:yy", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth0"

# Unknown net device (/devices/platform/mv643xx_eth_port.0/net/eth0)
(mv643xx_eth_port)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="xx:xx:xx:xx:xx:xx", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth1"

Where 'yy:yy:...' and 'xx:xx:...' are the mac addresses of the two
different machines.

Can I simply comment the above two lines to get things to work as
normally, or can I change the reference to eth1 to eth0? Perhaps,
someone has a better idea?

I do want to be able to boot from the original hardware using the same
disks as well as from the new...


Thanx in advance,


John Holland
