Title: Internal/External PH ROMs on Token Ring products
Date:  6/87

Summary:

TokenLink PLUS (3C605) boards and Token Connection for
3Servers (3C1060) come from the factory with the "PH" ROM
jumper set for Internal, not External.  The manuals indicate
in the pictures that the boards are preset for External,
though they mention it could be either.  IT IS OK THAT THEY
ARE SET FOR INTERNAL.

Details:

The original TI chip set needed 2 ROMs in external
sockets, so the PH ROM jumper was set for external.  The
latest revision of the chip set includes this code in the PH
chip, so it is unnecessary to add the 2 external ROMs, so the
jumper is set for internal.  On both boards you can now see
the empty sockets where there used to be chips.  We knew in
advance that this would happen, so we made it possible to use
the board either way. TokenLinks do not have the sockets because we
knew we had the  new version of the TI chip set.
