<pre class="k9mail"><div dir="auto">Hi Jon - it looks like it is OBP 3 on this machine so the MKP prompt appeared to work. If I reset (rather than power down) the mac values are displayed in the title screen.

I tried the watch-clock command and that worked as expected (the second timer showing)<br><br>Hi Peter - you mentioned a M48T58 - although this is definitely fitted with a M48T59. I wonder if the chip has been replaced previously with the wrong type? I've ordered a new M48T58 so will see if that works.<br><br>Thanks for the help all, much appreciated.<br><br>- Ian<hr>rescue list - <a href="http://sunhelp.org/mailman/listinfo/rescue_sunhelp.org">http://sunhelp.org/mailman/listinfo/rescue_sunhelp.org</a><br></div></pre></blockquote></div></body></html>
