'As appropriate' how? In the text of ecos.db?  In the existing files
associated with the VRC4375, in which case should I replicate these up at
some point in the tree as for 21143 on pc?

If there is something in the documentation that covers the procedure for
adding hardware support - and thus describes what I need to do - then please
point me at it.

I've replicated pc_giga as pc_tulip with the 21143 driver specified.  Now in
configtool I can do tools>templates and select that template, then generate
the build tree. However, I get a 'Hardware selection warning' that
CYGPKG_DEVS_ETH_I386_PC_I21143 is not present in the component repository.
How does one put it there?

I guess I'm in need of a step-by-step description of how to add hardware
configs, something like :-

    (1) edit ecos.db like so...
    (2) replicate/edit some files like so...
    (3) run such a tool with such a commandline and take these actions...

Cheers,

Mike
