Hi:
   Go to the htdocs/docs-latest directory and open index.html with a browser.
This is the index (the topmost file) for the latest docs available. Since all 
the liniks in the htdocs are relative browsing should be no problem. On Linux 
the docs are browseable using any browser as they should be on Win using 
MSIE.

Hi
  Yes, You can add a new directory to packages/hal. But better, if You can use 
an existing one (copy/rename), that allready suits Your needs, at least 
partially .

 The src files are normal c files, which You can edit freely, but you must 
preserve the original entry points and function returns.
 The syntax for the cdl files is very similar to tcl programming syntax ( eg 
cdl seems to be a tcl extension).

 Once You've created Your hal directory with corresponding cdl files, You must 
add the target into the packages/ecos.db file, which is also esentially a cdl 
file. (Just copy the original target definition , rename it to your target 
and modify the packages/hal directory in there. (Targets used to be defined 
somewhere near the end of ecos.db)

  But befor doing that You must obtain the most recent eCos documentation, 
which is also available from the cvs server. Just do

%mkdir htdocs
%cd htdocs
%cvs -d :pserver:anoncvs@sources.redhat.com:/cvs/ecos login
  You will be prompted for a password which is anoncvs.
%cvs -d :pserver:anoncvs@sources.redhat.com:/cvs/ecos -z 6 co -P htdocs

That's the way how I obtained the most recent eCos htdocs (it checks out in 
the docs_latest directory).

There's an eCos porting guide in there, too.
