320 This support changes various eCos semantics such as the encoding
321 of diagnostic output, or the overriding of hardware interrupt
323 Firstly there is \"Generic\" support which prevents the HAL
324 from overriding the hardware vectors that it does not use, to
325 instead allow an installed ROM monitor to handle them. This is
326 the most basic support which is likely to be common to most
327 implementations of ROM monitor.
