<DIV><FONT face=Arial size=2>Guys I need help / advice, </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have a problem with <EM>"</EM><FONT size=1><FONT
size=2><EM>General Protection Exception"</EM> on XO 1 it seems to be related to
overclocking:</FONT></FONT></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We have 30 XO from Peter (UK firends of OLPC) - no
problem with those, after introducing DevKey and disabling-security we can flash
XO with our version of Dex3/143 that includes overclocking and it
works.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Surprisingly 10 XO we got thanks to Urs from OLPC
Switzerland after flashing - crash with "<FONT size=1><FONT size=2><EM>General
Protection Exception" </EM>notice. It seems to be related to overclocking. (as
once turned off all works fine)</FONT></FONT></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any idea whether there is some more security we can
turn off? (apart form Devkey / disable-security)</FONT></DIV>
