RE: [eepro100] Sleep Mode Enabled

["David Peavey" <dpeavey@Kromos.COM>]

Hi Kallol,
Thanks for your help.  I will use the utility to turn off the bit.  However,
I am most curious about this because this may explain some of the problems
we are having.  I did a quick search of Intel's web site and was unable to
locate any mention of this.  Can you point me to the URL on Intel's web page
that discusses this?
Thanks in advance,
David

David,
   I was the person who found the problem while working in a HP lab.
The problem is well documented now and the description is available on
intel's page.

The mode has to be turned off, otherwise on high stress a read to ISR
registers results in master abort.

You could use Donald's eepro100-diag utility.
