I've used !FileFind to search the /contents/ of all files in
!Boot for the string '!Internet'.  I'm looking for something like
'Run xxxxxxxx.!Internet' which would run the file you have been
examining and have eliminated as the crash error source.

There are 3 such files (here in RISC OS 4.39):

Boot.:Choices.Hardware.Disabled.Boot.PreDesk.SetUpNet
Boot:Choices.Hardware.ID_0.Boot.PreDesk.SetUpNet
Boot:Choices.Hardware.Blank.Boot.PreDesk.SetUpNet

The first of these has a file:

Boot:Choices.Hardware.Disabled.Boot.PreDesk.TimeSetup

immediately following, which should be called immediately the
!Internet.!Run has finished.  The other 2 SetUpNet's have nothing
following, so the action moves elsewhere: I'm not sure of the
sequence of events in the very early stages of booting.

My suspicion is on 'TimeSetup', the whose contents (here) are:

If "<Inet$NTPServer>"="" Then Set Inet$NTPServer ntp.demon.co.uk
|do rtime  -ntp

Which matches (I think) my setting in Date_&_Time in the main
config window (use the demon ntp server, don't get time on boot).
If you /do/ get network time on boot, the 'do rtime -ntp' line is
not REMmed out[1].  The getting of network time occurs during the
initial boot (slow it down with Ctrl+Shift) immediately after the
toolbox unplugging and SetUpNet.


Does all that rather dodgy stuff give any clue? Eg, the network
time setting is broken in RISC OS 6.14?

Brian.

[1] The setting/unsetting procedure is slightly broken: you have
to tick/untick the 'Get network time on boot' box /and/ actually
get the time by clicking 'Get' in order to make the setting.
