Thanks alot for your follow-up !
I had a chance to test this just recently and
the results were as follows.

netconfig & hw |pg confirmed that the hw & network values
are similir on both machines.

The script did not seem to work for me on this laptop,
I ran it in a Unix window from SCO and it either just stood
working for a while and then a new #prompt came up.
Or it went into > mode.

But I tried to swap the harddisks just to see if
we might have any HW issues and this did not solve the problem,
so it might not be HW related after all.

I am npw trying to figure out exactly what the boot floppy in
the ticketing machine is supposed to fetch from the SCO laptop,
I am also curious about the processes (Procs) that are not running
on the cloned machine.

These were :

routed
snmpd
strerr
inetd (sorry, not initd indeed)

Might these be related and how can I start them manually ?

thanks again & cheers,
