<BR>
<P><FONT SIZE=2>you can use the verify /md5 command (it may be just verify in older code).</FONT>
<BR><FONT SIZE=2>this will compute a md5 hash which you can check against the md5 hash</FONT>
<BR><FONT SIZE=2>stored on CCO at the software download section. if the hash values match,</FONT>
<BR><FONT SIZE=2>the image is good. if it doesn't match, it got corrupted in transit or</FONT>
